Abstract:

Abstract:The calculation formula for optimum ventilation in fired power plants pulverzer are “computing power plants milling system technical
requirements” in accordance with DL/T 5145—2002.The accurate operation guidance can not be given as a result of imports ventilation measuring points and blending Blending Hardness of mill. The formula for calculating the above criteria is simplified and the milling system effectively reduces the loss on the basis of accuracy.A comprehensive and simplified error analysis are conducted.

Key words: Keywords:ball mill, optimum ventilation, HGI hardness, coal fineness
