Abstract :
The heat in waste gas is emitted into the atmosphere during power plant boiler operating, from the energy point of view, which has great potential of waste heat resources. Especially for the power plant boiler, if the exhaust gas temperature was decreased by 15~20°C, the boiler thermal efficiency will be increased about 1%. This paper takes a thermal power plant boiler´s rear flue for example, a waste heat exchanger was added, so that large number of waste heat in waste gas was recycled.
