Background

A thermal power plant, referred to as a thermal power plant, is a plant that produces electric energy using a combustible (e.g., coal) as a fuel. The basic production process is as follows: when the fuel is burnt, water is heated to generate steam, chemical energy of the fuel is converted into heat energy, the steam pressure pushes a steam turbine to rotate, the heat energy is converted into mechanical energy, and then the steam turbine drives a generator to rotate, so that the mechanical energy is converted into electric energy.

The prime mover is typically a steam or gas turbine, and in some smaller power plants, it is also possible to use an internal combustion engine. They generate electricity by taking advantage of the pressure drop during the conversion of high temperature, high pressure steam or gas through a turbine to low pressure air or condensate.

And the thermal power plant produces a large amount of waste gas during operation, wherein the waste gas refers to toxic and harmful gas discharged by human beings in the production and living processes. Especially chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the discharged waste gas has large odor, seriously pollutes the environment and affects the human health.
