Thermal secondary energy resources (SER)in metallurgical production can be divided into
high-temperature and low-potential energy sources (with temperatures below 50 C). We have
considered the ways of using low-potential thermal SER of a metallurgical plant. According to the traditional scheme, the circulating water is cooled in a cooling tower with the return of the heat of cooling to the environment.We propose to use a heat pump driven by a heat engine instead of a cooling tower. The scheme consists of a compression heat pump with a heat output of 4200 kW, a working agent R 600, a source of low-potential heat-circulating water: a 460 kW gas engine. The proposed scheme showed high efficiency of power supply of the town in comparison with the gas boiler
