Heat Recovery Power Generation

In the context of global energy crisis and increasing environmental pressure, the energy efficiency and environmental protection of coal-fired power plants are particularly prominent. Waste heat recovery and utilization technology is a key means to improve energy efficiency, reduce energy waste and reduce environmental pollution in coal-fired power plants. A large amount of waste heat is generated in the operation of coal-fired power plants, which mainly includes smoke exhaust waste heat, cooling water waste heat, slag waste heat and steam turbine cold end waste heat. These waste heat has high temperature, large flow, stable and reliable, and has high recycling value.The waste heat recovery and utilization technologies of coal-fired power plants mainly include cogeneration technology, heat pump technology and organic Rankine cycle technology. Cogeneration technology through the installation of turbine generator set, the use of exhaust heat and cooling water waste heat to generate steam, drive steam turbine to generate electricity, to achieve the joint production of heat and electric energy. Heat pump technology can use a small amount of electric energy to absorb heat from the low temperature heat source and transport it to the high temperature heat source, so as to recover the waste heat of cooling water and slag. Organic Rankine cycle technology uses organic working medium instead of traditional water vapor working medium to produce steam at lower temperatures to drive turbines and generate electricity.
