Jan 23, 2018· This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Coal mill, which is also known as coal grinding mill or coal milling machine, is used to pulverize and dry coal before it is blown into the power plant furnace in the coal-fired power plants. Coal mill is an important auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding.

Nov 17, 2012· Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower than 70%
