Waste thermal energy production refers to the technology that uses excess thermal energy in the production process to convert it into electrical energy.
Waste heat is the use of energy that is not used in production under certain technical conditions, i.e. redundant and wasted energy. It includes seven types: waste heat of high temperature waste gas, waste heat of cooling medium, waste heat of steam and wastewater, waste heat of high temperature products and slag, waste heat of chemical reactions, waste heat of combustible waste gases and waste. .
For example, the technology of high temperature flue gas recovery and power generation of steel industry heating furnaces can recover all costs in that year and increase the rate of 'usewe heat 5-10%. The production of waste thermal energy not only saves energy, but also benefits environmental protection.
