three factors affect limestone desulfurization efficiency

three factors affect limestone desulfurization efficiency

In the desulfurization process of powder plant, limestone powder is the most commonly used desulfurizing agent. The limestone desulfurization efficiency will directly affect the quality and efficiency of powder production process. And there are several factors that affect limestone desulfurization efficiency in powder plant. In this article, we mainly introduce these factors.

Generally, the content of calcium carbonate in limestone should be above 85%. If the calcium carbonate content is too low, it will cause some problems for the desulfurization because of the impurities in limestone, leading to the increase of absorbent consumption and transportation cost. The quality of limestone is decided by the content of CaO. The higher the purity of limestone, the higher the desulfurization efficiency will be. While designing the desulfurization process, the technique designer should not only calculate the chemical component of limestone, but also should know its physical properties.

The calcium oxide in the prime limestone should be between 48%~54%. But for the calcium oxide in limestone is not like the higher the better. For limestone with calcium oxide content above 54%, it will marbleize because of the high purity. Besides, it is hard to be ground and has stable chemical properties, which makes it not suitable to be used as desulfurizing agent.

The fineness of limestone powder is a very important factor that affects the desulfurization efficiency. In desulfurization process, to a large extend, the contact area decides the speed of chemical reaction. The finer of the limestone powder size, the larger the superficial area will be, so does the contact area of chemical reaction for per unit weight. Since the reaction rate of limestone is in proportion with its surficial area, so finer limestone particles has better ablation performance. In this case, the related reaction speed is also relatively higher, so does the desulfurization efficiency and use rate of limestone.

As desulfurizing agent, the properties of limestone include not only its chemical components but also its reactivity. The reactivity of limestone affects its solubility and dissolution rate. Under same use rate, limestone with higher reactivity has higher desulfurization efficiency to remove the SO2. Besides, when the reactivity of limestone is high, the use rate of limestone will also be high.

In order to solve such problems as low production efficiency and difficult installation and maintenance, ZENITH developed a new generation of jaw crusher--- C6X Series Jaw Crusher. It is the most ideal coarse crushing equipment on current market because a

As the new generation of crusher, PEW Series Jaw Crusher is born with innovative significance. The unique design concept makes this crusher achieve perfect combination between crushing efficiency and operating cost.

mobile stone crusher in india, portable crushing machine for mining plant

India has the potential to produce $400-500 billion worth of oil and gas, gold, silver, iron ore, copper, coal, calcium, rock phosphate and others. It is bound to generate substantial revenues for the government, which will be helpful in developing infrastructure for the country.

This will also create employment for 10-15 crore people, by setting up over thousands of new large, medium and small scale industries for processing natural resources. The GDP will improve and the current account deficit will come down, making it a win-win situation for all.

India is blessed with iron ore reserves, like Australia and Brazil, but the difference in production and outlook is immeasurable. Except iron ore, India also has abundant many other types of minerals, such as coal, bauxite, copper, limestone etc. Mining is the only sector with the true potential to make India an economic powerhouse.

Mining operation involves many different operations, including drilling, blasting, extraction, quarrying, crushing, grinding, screening, conveying, separation, processing etc. Crushing is the primary and integral operation in mining industry. Stone crushing can be operated in three stages according to production requirements. SBM provides complete range of crushing machine for mining plant and mobile stone crusher in India.

In stone crushing operation, the feeder or screens separate largeboulders from finer rocks that do not require primary crushing, thus reducing the load to theprimary crusher.The stone that is too large to pass through the top deck ofthe scalping screen is processed in the secondary crusher. Cone crushers are commonly used forsecondary crushing. Tertiary crushing is usually performed using cone crushers or other types of impactcrushers. Stationary crusher machine is gradually replaced by portable crushing machine due to its truly flexibility and mobility for various crushing applications.

Mobile Jaw Crusher Plant The mobile or portable jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials.Mobil jaw crusher is designed to crush all rock types from the hardest granites to abrasive ones and recycle materials.
