Coal Quality Correction Method of Boiler Efficiency for Economic Comparison of Different Running States of Boiler
The coal quality of boilers of thermal power units generally changes greatly.When comparing the economy of different running states of boiler,it is necessary to modify boiler efficiency by the coal quality.Based on the differential deviation method,this paper deduces the coal quality correction calculation formula of boiler efficiency,puts forward the method of using the arithmetic average of coal quality of all compared running states of boiler as the reference value of boiler efficiency coal quality correction,and gives a practical application example.The example results show that the coal quality correction of boiler efficiency should be paid full attention to in the economic comparison of running states of boiler.If the boiler efficiency is simply corrected to the design coal quality,a wrong conclusion may be drawn.
