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.

Journal of Physics: Conference Series PAPER OPEN ACCESS

First the coal from the stock yard is sent to mill to pulverize into powder. The pulverized coal is carried into boiler through the pulverized coal pipe by the primary air and a blower is used to blow the heated air. The combustion takes place and a fireball forms due to the tangential firing of coal and fuel oil at four different corners.

Coal pipeline Wikipedia

Coal pipelines are pipelines used to transport coal from where it is mined to where it is consumed. For very short distances, large trucks are used to transport coal, but trains and barges are preferred for long distances. In some cases it is more economical to move the coal by pipeline than by train or barge.

Coal mill pulverizer in thermal power plants

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 loss and
