Apr 10, 1990· A method according to claim 2, including detecting the mass flow of moisture in the coal entering the pulverizer and the wet coal mass flow at a feeder for feeding the coal to the pulverizer and calculating the moisture in the coal as a function of the mass flow of the moisture in the coal during the pulverizer and the wet coal mass flow at the feeder.
Dec 13, 2011· A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.
When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output. The higher the moisture, the lower the output.
Pulverized coal fired boilers use coal of several tens of micrometers in size and then fire such pulverized coal in a suspended state inside the boiler furnace. Roller mills are commonly used as pulverizers due to their low power consumption. They pulverize coal between a roller and a rotating pulverizing table. To meet society's needs for
