Resource-Saving System of Heat and Cold Supply in Power Complex of the Metallurgical Plant

Abstract:

This paper deals with the problem of energy efficiency improvement of the power supply system at the metallurgical plant. It is known, that up to 50-60% of metallurgical costs of production are energy costs, and there is a significant amount of thermal secondary energy resources, which can be used for heat supply in winter and cold supply in summer. For the organization of the system of waste heat utilization, it is proposed to use an absorption heat transformer, which operates in accordance with the scheme of absorption heat exchanger in winter, and in accordance with the scheme of absorption refrigerating machine in summer.
