8. Cogeneration(废热发电,热电联产 Cogeneration (also combined heat and power, CHP)is the use of a heat engine to simultaneously generate both electricity and useful heat The operation of a heat engine for any purpose is necessarily accompanied by the rejection of heat energy, often in large amounts The waste heat is generally dissipated into the atmosphere or an adjacent body of water with possible negative environmental effects A simple example of beneficial use of waste heat energy is using the heater in an automobile A cogeneration plant uses the rejected heat energy from electricity generator for space heating in cIties A cogeneration plant is usually a small, decentralized electric generating plants near the point of use, even right in the middle of a university campus.8. Cogeneration (废热发电，热电联产) Cogeneration (also combined heat and power, CHP) is the use of a heat engine to simultaneously generate both electricity and useful heat. • The operation of a heat engine for any purpose is necessarily accompanied by the rejection of heat energy, often in large amounts. • The waste heat is generally dissipated into the atmosphere or an adjacent body of water with possible negative environmental effects. • A simple example of beneficial use of waste heat energy is using the heater in an automobile. • A cogeneration plant uses the rejected heat energy from electricity generator for space heating in cities. • A cogeneration plant is usually a small, decentralized electric generating plants near the point of use, even right in the middle of a university campus
