The waste heat power generation technology is introduced in detail

Waste heat is the heat emitted by the fuel combustion process after the completion of a certain process. Waste heat power generation is the ability to convert excess heat energy in the production process into electricity. Waste heat power generation is not only energy saving, but also conducive to environmental protection. In steel, petrochemical, building materials, cement, sugar and other professions.

It has a lot of low-grade waste heat (generally below 500 ° C), including low-grade flue gas, steam and hot water. At present, the waste heat power generation skills that have been put into operation or project research mainly include the following occupations: cement occupational kiln waste heat power generation skills, coke oven tail gas waste heat recovery power generation skills, iron and steel occupation sintering waste heat power generation skills and dry quenching waste heat power generation skills, building materials occupation float glass line waste heat power generation skills, petrochemical occupation waste heat power generation skills.

Because waste heat power generation is only a small part of the entire industrial production system, and then different from conventional thermal power plants, it must meet the needs of the entire production process, production equipment, and then has the following characteristics: to heat power. Because the entire system heat load is unstable, for example: some production is periodic.

Some high-temperature products and slag emissions are intermittent, and some process production is continuous and stable, but the heat provided by the heat source will also shake with the production of wavering, so waste heat power generation needs to be based on the residual pressure of the production of heat or the residual heat generated in the production process to determine the power generation.
