Power plant is the main source of smoke dust, Synthetic Organism and atmospheric impurity. And the desulfuration, denitration and dust extraction becomes the public attention question because it relates our living environment.
Sulphuris the detrimental impurity in coal. Although it does not affect burning itself, it has a serious pollution to environment and corrosion to device if it is of high content. So the sulphur content should not be too high in coal which is used for burning in power plant.
So far, the world desulfuration installed capacity has overcome 5 billion KW with 85% heat-electric engine has installed the desulfuration devices. 90% of them are installed in the recent 5 year with 30-40 year’s lifespan. Owning to its high rising price of coal and the quality of electric coal become poor, the sulfur content is rising high, which causes the pollution of sulfur content in the air. In recently years, the world has formulates a series of laws and regulation, technical policy and planning, which has make a higher requirement of the pollution waste emission control.
The world has a stronger support to the electric power environmental protection industry with the flue gas denitration industry at a high speed development. Liming Heavy Industry absorbs European advanced technology and combines with its many years grinding mill design concept and market demand, and designs all kinds of mill such as Raymond mill, LM vertical mill, super-pressure trapezium mill, high-pressure suspension mill, three-ring medium-speed mill, etc. The high efficient and environment mill satisfy the demand of social development, which win the consistent high praise in the heavy industry. Vertical mill is specially for desulfuration in electric plant with high efficient grinding, low consumption of metal and simple craft flow.
