High energy-consuming enterprises refer to some large energy-consuming enterprises in steel, chemical industry, building materials and other industries.
These usually use various industrial furnaces that consume a lot of fuel, such as blast furnace, converter, sintering furnace in steel mills, coking furnace in coking plants, various smelting furnaces in non-ferrous metal plants, rotary kiln in cement plants, tank kiln in glass plants, tunnel kiln in ceramic plants, chemical plants, sulfuric acid reactors in pesticide plant and so on.
All kinds of high-temperature industrial kilns will emit flue gas, which can be divided into high temperature, medium temperature and low temperature according to the flue gas temperature. The higher the temperature, the more high-grade energy, the more recyclable energy and the greater the power generation.
The process flow of waste heat power generation is that the flue gas passes through the waste heat boiler to exchange heat, and the boiler generates steam, which is input into the steam turbine to drive the generator to run.
The technical core of waste heat power generation is high efficiency heat exchanger and high efficiency steam turbine.
Construction process of waste heat power generation: design scheme, equipment procurement, civil engineering, installation, commissioning and operation.
The construction contents include: boiler installation, turbine generator set installation, civil engineering of main workshop and circulating water pool, electrical system and its connection.
Three main engines: waste heat boiler, steam turbine and generator.
Pure low-temperature waste heat power generation is to use the energy of low-temperature flue gas without replenishing fuel.
Number of personnel in waste heat power station: generally greater than 14.
Installed capacity of waste heat power station: generally 3MW-20MW.
Construction period of waste heat power station: 9 months to 18 months.
Investment scale of waste heat power station: tens of millions to hundreds of millions.
