Research and application of an adaptive temperature wind energy saving technology of 300 MW coal burning boiler

Abstract

Abstract:

Abstract:In order to reduce the exhaust gases temperature of the No.7 boiler of the Huadian International Shiliquan Power Plant,to improve the thermal efficiency of the boiler,the modification technology of inputting cool air into the pulverized coal system ,which made the No.7 boiler unit save energy, automatically adjust the rate of the cooling air input quantity according to the power load, coal quality and other factors.With these technology reform, the input quantity of the cool air was great reduced,the temperature of the flue gases exhausted was decreased,which saves the energy,improve the boiler unit economic.
