A waste thermal power generation project refers to an engineering project that uses sensible or latent heat from waste gases, wastewater, waste residues and other media generated in industrial production to convert thermal energy into electrical energy via appropriate equipment. For example, waste thermal energy can be used to heat water to generate steam to drive a turbine-generator unit to produce electricity, such as: waste thermal energy generation project of cement kiln, steel sintering cooler waste thermal energy generation project and waste; is burned to generate steam to drive a steam turbine or use gas-steam combined cycle method to generate electricity, such as steel blast furnace gas power generation, thermal power generation residual ofcoalbed methane, etc.
Does the cement-based thermal power plant use a lot of water treatment chemicals to circulate the water?
Yes.
In the waste thermal power generation process, pure water is pumped from the feed water pump to the hot water well of the condenser, merged with the steam worn after work and pumped into the bottom-outlet collector of flash evaporator under pressure and outlet by Convergence condensate pump.
The water injection tank supporting the 450 square meter sintering waste thermal power generation steam turbine is used to supply cooling water to the sintering pump. water in order to maintain the condenser operating in a high vacuum state and to better improve it. the efficiency of the steam turbine, it is necessary The cooling water in the water injection tank must be constantly rlocated.
Circulating water agents are not widely used in cement-based waste thermal energy production. After all, the installed capacity of residual thermal power generation is not very large, usually around 3 MW. Therefore, the circulating water volume of the circulation. The water system is relatively large. According to “Xingerui” “Judging from the experience of the past two decades, the amount of circulating water treatment chemicals used in cement waste thermal energy production is about 10W, or even less .
