The Power of Hot Water: Electricity From Low-Temperature Waste Heat (Room 320)

Around 10% of the primary energy input to a reheating furnace is lost to skid cooling water. The low temperatures usually observed in the cooling loop result in this stream being overlooked as a useful source of heat. However, with only minor modifications, the temperature of the cooling loop can be raised with no adverse effect on the cooling process. When raised to 90-100°C, the water is sufficiently hot to drive novel low-temperature energy conversion systems that produce electricity while reducing the cooling duty on the furnace.
