Abstract:

Abstract:In a power plant, the exhaust gas teperature was higher than designed value by 40℃. Aiming at this problem, the practical coal quality, the air leakage, the combustion situation and the cleanliness of the heating surface were analyzed. The control measures for reducing the exhaust gas temperature were proposed, and the efficiency and economy of the boiler were improved effectively.
