The types of waste heat power generation are introduced in detail

High temperature waste heat generation using dry hollow kiln tail 900? 1000 degrees of hot gas to generate electricity. It has been withdrawn from the historical stage with the screening of hollow kilns. Medium and low temperature waste heat power generation uses the low temperature gas discharged from the cement pre-differentiation kiln and the high temperature gas fired from the secondary combustion boiler to mix into medium and low temperature gas for power generation.

High pressure saturated steam and high temperature hot water are produced first, and the steam volume, steam pressure and steam temperature are adjusted to the parameters required by the turbine to generate electricity through the secondary combustion boiler (which requires part of the fuel consumption). In the 1990s, this type of power generation was selected, and now it is not advocated to promote medium-low temperature waste heat power generation.

Pure low temperature waste heat power generation using cement pre-differentiation kiln tail discharge of 300? 400 degrees and cooling machine 150? The low temperature gas of 200 degrees is used to promote the low parameter turbine unit to do power generation, and the power generation system has no external heat source. The Chinese government initiates and encourages the use of low-temperature waste heat power generation. Low temperature waste heat power generation has become the first measure for cement companies to reduce costs and reduce emissions, and it also meets the world's requirements for carbon reduction technology.
