Abstract
Disclosed is a heat recovery system of a plant using a heat pump that absorbs some heat energy wasted from a condenser of the plant. The heat recovery system is constructed such that water condensed by the condenser is supplied to a service water heater via condensate pumps. A heat pump is installed between the condensate pumps and the service water heater for receiving the condensed water and the coolant. Some of the condensed water and the coolant, having passed through the heat pump, are supplied to a coolant inlet port of the condenser, and the remaining portions are supplied to the service water heater. The condensed water supplied to the service water heater is heated by a three way valve through which service water heating steam is supplied. Some of the steam is directly recovered to the condenser via a combustion air heater.
