Analysis on reasons of low boiler efficiency of a 300 MW unit

Abstract

Abstract:

Abstract:aiming at the problem of lower efficiency of a 300 mw boiler, some experiments were carried out, which include the boiler efficiency test, the draft fan efficiency test,he experiment of air leakage rate of the air preheater, the oxygen meter calibration test and the oxygen fileld calibration test.finally, the reason of lower boiler efficiency is that the indicated value of the oxygen meter in inlet of the air preheater was lower than the true value. The operation oxygen was reduced to 1. 14 % ,the boiler operation efficiency raised by 0. 52 percentage, the house power consumption rate reduced by 0. 34 percentage, and the coal consumption rate reduced by 2. 7 g/( kw· h) .
