Analyze the method of waste heat power generation in detail

The skill of using the residual heat energy in the industrial production process to convert it into electricity is called waste heat power generation skill. The important equipment of the waste heat power generation system is the waste heat boiler, which uses the heat or combustible substances in the working medium such as waste gas and waste liquid as a heat source to produce steam for power generation. The general waste heat power generation system can be divided into two methods according to the use of waste heat resources.

It is a waste heat power generation system that uses the heat energy released in the industrial production process with a temperature lower than 230 ° C to directly drive low-grade thermal steam turbine to generate electricity. It is a waste heat power generation system that uses waste heat boiler to absorb the waste heat and produce steam in the industrial production to drive the turbine to generate electricity. The important equipment of waste heat power generation is waste heat boiler, also known as waste heat boiler.

It uses the heat or combustible substance in various working substances such as waste gas and waste liquid as a heat source to heat the working medium to produce steam. If only waste heat is used, no combustion equipment is required; If combustible materials are used, special combustion equipment is required. In the design of waste heat boiler, the heating surface is usually arranged reasonably according to the characteristics of the working medium and process and the characteristics of the exhaust gas (including flow rate, temperature, composition, ash content, pressure and other parameters).
