Coal Mill an overview ScienceDirect Topics

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.

31/7/2020· Due to shorter retention time of coal dust in the mill, needs a little higher temp at mill outlet than in lab oven. At the same time mill outlet temp to maintain 20 0C above the dew point temp and for bituminous coal dew point temp is found to be 33–35 0C. Secondly the speed of combustion is increased with reaction surface of coal particles and the temp. The surface is increased by grinding

17/11/2012· 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% mean higher carbon

Coal-mill optimisation in coal-fired power stations aids

The fineness of the coal powder and the uniformity of the coal flow sent to the burners are crucial parameters to achieve an effective combustion in coal-fired power plants. Coal pulverisers or coal mills are the heart of a PCF boiler. Often, the root causes of non-optimised combustion lie with the pulverisers. Capacity, reliability, and environmental issues such as slagging, fouling, and
