rotary kiln incinerator - design and manufacture

The rotary kiln incinerator is manufactured with a rotating combustion chamber that keeps waste moving, thereby allowing it to vaporize for easier burning. Types of waste treated in a rotary kiln incinerator

The picture"photo 1"gives a schematic overvieuw of the systemmanufactured totreat the waste in a rotating drum, we use a counter current rotary kiln. There are 2 different types of rotary kiln, co-current rotary kilns and counter current rotary kilns. Read here more about the different types of rotary kiln.

Energy recovery is always an individual design, and very attractive is electricity. But electricity is also the most complicated and less economical profitable for small installations ( the min. capacity is 3 ton/h of waste). If heat can be used in another process on site, for example in a dryer. It has to be taken into consideration that a connection between incinerator and the production process (dryer) can be the most efficient solution. The disadvantage can be if there is a production stop of the incinerator, the process (dryer) can not always stop at the same time.

For example : We produce steam as energy recovery, also for electricity production. The post combustion is strictly vertical and the boiler also has a vertical design for evacuation of dust. Our design is made for continuous operation of a steam boiler. The next drawing gives a possible set up of the installation. This is our set-up, created by people with operation experience with incinerators, and it results in this lay-out.

Depending on the amount of Chlorine, S, N or other chemicals in the waste stream there is a wet or/and dry scrubbing system available for the flue gas treatment. Flue gas treatment systems are standard systems, and normal chemical reaction. So, for correct flue gas treatment we need to take care for:

rotary kiln incinerators on the rise in waste management

rotary kiln incinerators on the rise in waste management

Incineration has become an essential tool in managing industrial and municipal wastes more sustainably, as long-landfilled materials such as hazardous medical wastes, petrochemicals, ammunitions, and more, have proven detrimental to the environment.

While many types of incineration equipment exist, the rotary kiln, a diverse and flexible thermal processing machine, continues to gain market share as the preferred method of incineration for a number of reasons.

While an increasing focus on sustainability has improved waste generation and recycling, many wastes are simply not suitable for reuse or recycling. When recycling or reuse is not a viable option, incineration provides a much-needed outlet for wastes that cannot be recycled economically, or because of concerns over hazardous or toxic components.

Incineration significantly reduces the volume of waste by converting it to ash. This reduction in volume is a major environmental benefit, decreasing the amount of space the material will take up in a landfill and ultimately contributing to a declining need for landfills. A reduced volume also makes transportation more efficient (and more economical) because less hauling is required.

When disposed of, hazardous components pose environmental threats to soil, air, water, and human and animal life. Through thermal decomposition, incineration eliminates hazardous components from the waste, taking them out of the environment completely and preventing any potential associated environmental degradation.

Rotary kilns are used to carry out physical changes and chemical reactions in a variety of industrial settings. They are often chosen for their high-capacity and continuous production. When it comes to incineration, however, they are selected for one simple reason: flexibility.

The ability to simultaneously handle multiple waste streams has become essential in todays waste processing market. At one time, it was not uncommon for large manufacturers to have their own in-house incineration facility to handle the waste they produced, but as waste management became more complex, the industry moved to outsourcing incineration needs to avoid managing on-site facilities and the many complexities that accompany the task.

This developed into waste handling companies that collect waste from multiple sources and process it for a fee, which has since become the industry norm. In this type of business model, the rotary kiln provides the ideal processing solution, as waste processors need something that can handle the diverse range of waste streams they collect. If not for the rotary kiln, these processors would require multiple different types of systems to manage these waste streams.

The rotary kiln is also capable accepting feedstocks of varying moisture content and particle sizes, reducing the need for pre-treatment in many cases; from barrels to material fines, shredded waste, and everything in between, rotary kiln incinerators accept it all.

In addition to the industry as a whole changing, the make-up of the waste itself is changing as well. While advancements in technology are producing more sophisticated products than ever before, they are also yielding more complex waste streams.

The process parameters of incineration may vary depending on the types of wastes being handled. In general, however, incineration employs controlled temperature profiles in order to volatilize organic components in the waste, thus eliminating hazardous compounds.

Though indirect-fired kilns are available, almost all rotary kiln incinerator systems utilize a direct-fired rotary kiln, where the products of combustion are in direct contact with the waste being processed. Material and combustion gases are fed into the rotating drum, which is sealed at both ends to maintain the required temperature profile within the kiln.

Most incinerators are configured with a co-current air flow, meaning the material and products of combustion flow parallel to each other in the kiln (i.e., the waste material and combustion products are fed into the kiln at the same end).

Although these components are available separately, they are best purchased as a complete system from a single-source provider, as there are many integrated components and regulatory requirements that can be difficult to manage independently.

Incineration provides a valuable opportunity to manage both non-hazardous or hazardous wastes that are otherwise not economical or practical to recycle or reuse. As the incineration industry evolves to handle more complex and diverse waste streams, rotary kiln incinerators are becoming increasingly more widespread.

rotary kiln incinerator for sludge incineration

rotary kiln incinerator for sludge incineration

Sludge is a common solid waste in daily life, which is commonly found in sewer pipe networks and sewage treatment plants. The amount of sludge waste produced in the industry is huge each year, among which electroplating sludge, leather sludge, pickling sludge, oily sludge, sewage sludge, and other types of sludge discharge are increasing day by day.

The sludge waste contains a lot of harmful substances, including heavy metals, bacteria, pathogens, etc. If it is not treated, it will inevitably have a greater impact on the environment and human health. Sludge treatment came into being under such circumstances. Sludge treatment is the reduction, stabilization, and harmless processing of various types of sludge such as concentration, conditioning, dehydration, stabilization, drying, or incineration.

There are roughly four methods for sludge treatment in the world, namely reclamation, landfill, incineration, and land use. Most landfills are open-air sites. After the rain, a large amount of sludge containing oil that is difficult to degrade organic matter, heavy metals, and pathogenic microorganisms will corrode and penetrate the land, posing safety hazards to the soil, and causing new pollution to the surrounding environment of the city. In Europe, the treatment of sludge through sludge incineration has become a very important way. Due to stricter restrictions on sludge accumulation, incineration of sludge may become the only way to treat sludge.

The sludge incineration process needs to be carried out in a sludge rotary kiln. Sludge waste rotary kiln is a kind of hazardous waste rotary kiln incinerator, which is specially used to treat sludge waste. It is a rotary kiln calcining equipment integrating drying, heating, and calcination. During the sludge incineration process, all germs and pathogens are completely killed by the high temperature in the sludge rotary kiln, and the toxic and harmful organic residues are decomposed by thermal oxidation. The sludge is incinerated through the sludge rotary kiln to achieve the greatest reduction in volume, and the final product incineration ash is obtained. Incineration ash can be used as a raw material for cement production to fix heavy metals in the concrete to prevent them from re-entering the environment.

The internal temperature in the sludge rotary kiln incinerator is generally between 1350-1650, or even higher. The materials in the kiln are in a highly turbulent fluidization state during the incineration of sludge. Therefore, the harmful organic matter in the sludge in the kiln can be fully burned, and the incineration rate can reach 99.999%. Even stable organic matter such as dioxins can be completely decomposed.

Since the feeding point of the dried sludge is in a decomposition furnace higher than 850C, the furnace has a large heat capacity and a stable temperature, which effectively inhibits the formation of dioxin precursors. The practice of disposing of toxic and hazardous wastes in cement kilns at home and abroad shows that the concentration of dioxin emissions produced by waste incineration is far below the emission limit.

The waste gas and dust discharged from calcination are collected by the bag filter at the end of the kiln as cement raw materials and then enter the kiln for calcination. No hazardous waste fly ash is generated.

The refractory bricks, raw materials, kiln skin, and clinker in the sludge waste rotary kiln are all alkaline, which can absorb SO2, thereby inhibiting its emission. In the process of cement firing, the heavy metals in the sludge and slag can be fixed in the structure of the cement clinker. So as to achieve the role of being cured.

Through the treatment of the rotary kiln incinerator, the organic and inorganic components in the sludge can be fully utilized, and the resource utilization efficiency is high. The sludge contains some organic matter (above 55%) and combustible components, which will generate heat when calcined in the rotary kiln. The low calorific value of sludge is about 11MJ/kg, which is equivalent to lean coal in the sense of calorific value. Lean coal contains 55% ash and 10%-15% volatile matter and has a calorific value of 10-12.5MJ/kg.

The sludge rotary kiln incinerator has higher treatment efficiency, the incineration products can be used as cement raw materials, and the heat produced by incineration can be used for power generation, with significant economic benefits. It has become the first choice of incineration equipment for many sewage treatment plants and industrial solid waste treatment enterprises.

hazardous waste incineration in a rotary kiln: a review | springerlink

Hazardous waste output in the world is increasing every year. To achieve higher efficiency and lower pollution, the incineration technology for hazardous waste needs to be studied further. This study mainly reviews the research progress in incineration, slagging, and pollutant emission in the rotary kiln in China and abroad in the last 10years, and conducts a comprehensive analysis and evaluation of the research. Considering that there are many variables involved in the incineration process, the incineration law cannot be validated in a limited timeframe by experiments. Researchers often use computer simulations to predict and verify the incineration process through experiments and to provide reference opinions for commercial operations. Through the analysis of the research progress in rotary kilns, it is observed that the basic research in rotary kilns is becoming mature. The latest research trend in rotary kilns is interdisciplinary and mixed research. From a new perspective, further research should be focused on a comparative analysis of the rotary kiln and the cement kiln, full life cycle assessment of the impact factors of rotary kiln on the environment, the impact of the factory treatment process on the workers health, etc. The research direction of rotary kiln in China and abroad for the future has been predicted reasonably.

extending refractory lifetime in rotary kilns for hazardous waste incineration - sciencedirect

extending refractory lifetime in rotary kilns for hazardous waste incineration - sciencedirect

The main costs for modern rotary kiln incinerators are refractory brick maintenance. Every 13 years, parts or the entire brick lining has to be renewed due to refractory wear and tear. Often, the blame is laid on thermo-chemical corrosion. To reassess this prevailing dogma, a comprehensive wear mechanism was elaborated that includes the impact of bottom ash characteristics at operating temperatures. Thermodynamic calculations were employed as well as a post-mortem analysis of refractory bricks from three rotary kilns. Changes in chemical and mineralogical composition and microstructure were examined. Surprisingly, results show that there is no significant thermo-chemical reaction between refractory material and the molten bottom ash. In fact, the melt penetrates open pores by capillary action up to 5mm in depth. Under this infiltrated zone, serious cracks are systematically visible in all type of bricks. We suspect a mismatch of thermal expansion coefficients to be the cause of crack initiation. These cracks lead finally to spalling of degraded refractory layers. Therefore, refractory materials used nowadays are not optimal. To conclude, experimental based guidelines are provided that may help operators extend the lifetime of the refractory bricks and reduce maintenance cost significantly.

thermal co-treatment of combustible hazardous waste and waste incineration fly ash in a rotary kiln - sciencedirect

thermal co-treatment of combustible hazardous waste and waste incineration fly ash in a rotary kiln - sciencedirect

Fly ash was treated together with combustible hazardous waste in a rotary kiln.At least 90% of inserted fly ash were transferred to the bottom ash.The quality of bottom ash was not impaired.Heavy metals were immobilised by thermal treatment.Continuous operation of the rotary kiln was not impaired.

As current disposal practices for municipal solid waste incineration (MSWI) fly ash are either associated with significant costs or negative environmental impacts, an alternative treatment was investigated in a field scale experiment. Thereto, two rotary kilns were fed with hazardous waste, and moistened MSWI fly ash (water content of 23%) was added to the fuel of one kiln with a ratio of 169kg/Mg hazardous waste for 54h and 300kg/Mg hazardous waste for 48h while the other kiln was used as a reference. It was shown that the vast majority (>90%) of the inserted MSWI fly ash was transferred to the bottom ash of the rotary kiln. This bottom ash complied with the legal limits for non-hazardous waste landfills, thereby demonstrating the potential of the investigated method to transfer hazardous waste (MSWI fly ash) into non-hazardous waste (bottom ash). The results of a simple mixing test (MSWI fly ash and rotary kiln bottom ash have been mixed accordingly without thermal treatment) revealed that the observed transformation of hazardous MSWI fly ash into non-hazardous bottom ash during thermal co-treatment cannot be referred to dilution, as the mixture did not comply with legal limits for non-hazardous waste landfills. For the newly generated fly ash of the kiln, an increase in the concentration of Cd, K and Pb by 54%, 57% and 22%, respectively, was observed. In general, the operation of the rotary kiln was not impaired by the MSWI fly ash addition.

hazardous waste incineration plant is the most efficient way

hazardous waste incineration plant is the most efficient way

Hazardous waste incineration plant is a good way to handle hazardous waste. Hazardous waste is generated in several activities and businesses, like hospitals, chemical manufacturing, dry cleaners, hospitals, and others. Even light bulbs, phones, televisions, garden pesticides, and computers can become hazardous if they are dumped in landfills. Try this hazardous waste incinerator. Get the egg tray machine China right now.

In earlier times, most hazardous wastes were dumped in landfills and this resulted in their seeping into the ground and polluting water sources. Today, most of this dangerous waste is destroyed in incinerators at high temperatures and this not only renders them harmless but also allows the generation of energy from the gases that are released during this process. Using incinerators to destroy hazardous waste has been considered the best demonstrated available technology, as it eliminates toxic constituents from it, and greatly helps in the reduction of the volume of waste. Besides, the MSW sorting equipment is also a good machine for recycling waste. The sewage sludge carbonizing machine can process sewage sludge well.

Incineration of hazardous waste coverts it into ash, flue gas and higher temperatures. The ash that is produced comes from the inorganic waste and can be as particulates or solid lumps that are carried by the produced flue gases. Flue gases can be discharged into the atmosphere after they are cleaned of any pollutants, gaseous or solid. Where the waste produces high temperatures, this heat can be used in the generation of electric power.

During the incineration of this waste, its solid mass reduces by up to 85 percent and its volume by 95 percent. Thus, there is no complete elimination of the need to use landfills, but the high reduction in volumes can prove advantageous. Incineration has been found very useful when it is used to destroy clinical waste that contains a high amount of pathogens and toxins, and here the high temperatures lead to their being destroyed and the waste made harmless.

Most hazardous waste incinerators have a rotary kiln, an afterburner, and a system for controlling any air pollution. Both solid and liquid wastes are introduced into these rotary kilns, and temperatures are maintained above 1800 degrees Fahrenheit. To maintain these high temperatures use is made of the heat content of any liquid wastes or through the use of supplemental fuels. Natural gas is often used for this. The rotation of the kilns is slow so that all sides of the solid waste are exposed to the high temperatures that are in the kiln. Combustion efficiency is increased through the use of mechanical ventilation that increases the air in the kiln. If you wanna sort waste into different types, try garbage recycling machine. Then use charcoal making machine to make wood charcoal. Read details https://bestonmachinery.com/pellet-machine-for-sale/wood/.

Any vapor from the incineration process in the kiln goes to a secondary chamber, where it is then oxidized for a few seconds at 2600 degrees Fahrenheit. This vapor is then cooled and passed through a heat exchanger that reduces its temperature considerably down to 700 degrees. The vapor is then quenched and scrubbed as part of the air pollution control process.

High-temperature incineration of hazardous waste destroys it at a cost-effective price. Any energy recovered helps to reduce costs. It decreases the load on landfills while going a long way in preventing dangerous materials from leaching out and polluting water sources. It is a process that is both safe and efficient. Look at this reputable company Beston Company.

rotary kilns

rotary kilns

The three rotary kilns in Antwerp provide thermal treatment for industrial and hazardous waste that is not eligible for recycling. One of these is MediPower, which treats medical waste in a safe and sustainable manner. Indaver uses the steam released by incineration to heat its own buildings. After conversion, the electricity is used for its own installations or supplied to the grid.

Most waste is delivered in bulk. Thedriver empties the contents of the truck into the bunker, where grippers are used to pick up the waste and deposit it into the filling shaft and on into the rotary drum. Barrels containing mainly hazardous waste are stored separately and, depending on their contents, are emptied, shredded or placed immediately in the kiln.

Liquid waste is delivered via the tank park, where it is pumped into the kiln via aboveground pipelines. In 2012 the tank park was expanded to guarantee the safe treatment of liquid waste; this way Indaver ensures a buffer. Viscose waste that cannot be pumped is brought into a paste tank; liquid waste that should be minimally manipulated can be injected into the kiln via direct injection.

Waste is incinerated in rotary kilns at temperatures between 1,000C and 1,200C. From the rotary kilns the waste is sent to the post-combustion chamber where hazardous waste can be completely incinerated.

The flue gases are dedusted in an electro filter, in a four-step wet gas washing with various chemical flows, and finally led through a dioxin filter and released via a chimney. The gasescomply with the strictest environmental standards.

The three installations serve as each others back-up facility. The Indaver rotary kilns in Germany can also be used as back-up. If necessary, the waste can be transported directly to one of the other installations; so long-term storage or transfer to third parties is redundant. This way Indavercan guarantee an efficient, safe and completely reliable solution for its industrial customers.

Indaver uses the steam generated during thermal treatment for its own buildings and processes (such as solvent recycling) or for neighbouring companies, such as Amoras, the dewatering installation in Port of Antwerp. A powerful turbine also converts the steam into electricity for the grid. The heat we recover at the Antwerp site can supply energy to 9,000 households.

The MediPower installation treats hazardous waste, also known as Regulated Medical Waste (RMW), other packaged waste from the pharmaceutical and chemical sectors and liquid waste. Indavers MediPower is one of the largest and most modern facilities in the world for treating this type of waste, with a very high degree of energy recovery.

Safety is foremost at Indaver. After the initial check for processing, the RMW is kept in a separate acceptance hall on pallets fully wrapped in foil. The packaged hazardous medical waste is brought to the kiln via an automatic feeding system on conveyor belts, pushers or lifts so that the employees cannot be contaminated or wounded by sharp objects.

Incineration in the rotary kilns at high temperatures guarantees as complete as possible destruction of all contaminates, such as bacteria and potentially infected material. During gasification in the rotary kiln, Indaver safely treats hazardous elements, such as mercury and cytostatics (cancer drugs).

Indaver tries to recover as many materials as possible from waste for the purpose of recycling and reuse. However, certain waste flows, including critical and sensitive waste from the chemical and pharmaceutical industries, require thermal treatment to prevent hazardous substances from finding their way into the material or food chain. For that purpose, we have rotary kilns.These completely destroy hazardous components through a combination of high temperature, intensive mixing and time, resulting in homogeneous and complete combustion. This makes the rotary kilnsimportant links in the circular economy for Indaver, because they help keep the product and material chains clean and safe.
