coal mill in thermal power plant - digital-dynamicsin. Coal mill pulverizer in thermal power plants - SlideShare 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,
2020-7-7The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.
2015-10-5The Gravimetric Feeder compensates for the variation in bulk density by feeding a fixed weight of coal in response to a boiler demand. This ability to accurately weigh the coal on an as-fired basis provides significant improvement over volumetric feeders in terms of matching the BTU delivered by the feeder

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 Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber furnace.. The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
