Utilization of Waste Heat of Circulating Cooling Water in Hot-Stamping Power System

Abstract:

This paper studies the possibility of using heat pump instead of cooling tower to decrease temperature and recover waste heat of circulating cooling water of power system. Making use of heat transfer theory the paper carried on analysis and calculation about recoverable waste heat of circulating cooling water in hot-stamping power system which includes hot-stamping, closing in and extrusion intermediate frequency induction furnace. The results show that the whole process can recover calories which is 2.642×106kJ per hour.Using the recycled calories can make 15.82 tons hot water per hour which is 60°C. This research shows that using heat pump to recover the waste heat of circulating cooling water is effectual.
