热电联产的供能方式是节约能源、减少环境污染的有效方式,在最大经济供热半径范围内,比冷凝式火电厂供电、分散小型锅炉房供热的热电分供方式具有优越的经济性,其原因在于它的热电总能量在满足用户要求的条件下,成本少。热电厂将燃料的化学能转换成两种不同质的能量,即热能和电能供给用户,确 The cogeneration mode of energy supply is an effective way to save energy and reduce environmental pollution. Within the scope of the maximum economic heat supply radius, it is superior to the power supply of the condensing thermal power plant and the disperse heating of the small boiler room. The reason for this is that the total energy of its thermoelectricity meets the requirements of the user and the cost is low. The thermal power plant converts the chemical energy of the fuel into two different kinds of energy, that is, thermal energy and electric energy supply users.
