Engineering test of energy saving effect and flue gas purification for the flue gas condensation heat recovery device

Based on an energy saving reconstruction project of smoke exhaust waste heat utilization for the boiler room and simulation of power plant operation conditions, tests the energy saving effect and flue gas purification of the device in conditions of different excess air coefficient. The result shows that the device improves the gas utilization thermal efficiency with a considerable recovered rate of the flue gas condensation water and improves the flue gas purification effect markedly. The flue gas condensation water shows strong acidity therefore the anti-corrosion treatment of the device is necessary.
