The grinder mill or pulverizer machine has a wide range of application in electric power industry, and one of the important area is coal desulfurization system of coal-fired power plants.
Power plant desulphurization system mainly refers to using a set of complete process to control sulfur dioxide emissions in the process of power generation coal burning to achieve the requirements of environmental protection. At present, environmental protection in our country is getting more and more serious, and the so2 content in city air is rising, so as the main body of the coal consumption and emission, the sulfur dioxide emission of coal fire power plant accounts most of the whole society. Therefore, controlling the discharge of sulfur dioxide coal is China's control key of sulfur dioxide pollution, among which the most important is gradually controlling the sulfur dioxide emission of power plant.
At present, coal washing technology, clean coal combustion technology, and using low sulphur coal and flue gas desulfurization technology are the main ways to reduce sulfur dioxide emission of power plant. But currently, coal washing and screening has not had effective removal techniques for the organic sulfur coal, and coal organic sulfur composition is higher in the high sulphur coal production area in our country, therefore, this method has great limitations. Clean coal combustion technology although has been mature commercial technology in international, but single capacity is not large, and the technology has requirements of big investment and high technical, so it is difficult to be widely used in China in a short time. And compared to see, flue gas desulfurization technology is more mature. Therefore, at present, the key and effective means to control sulfur dioxide emission of power plant in our country is flue gas desulfurization
