In recent years, the load following capability of thermal power plants has been actively researched, as power system interconnection unavoidably brings about complicated load variations. The key to improving the load following capability is the control of the fuel supply to the burner, which is provided by the coal mill. The conventional method of controlling the coal mill is by a PID system ...

Investigation of mercury release from lignite in power plant mills. At two power plants, lignite samples (Lignite A and Lignite B) were taken simultaneously at the feeder before entering the coal mill and from the dust line after the coal mill. Afterwards, the raw lignite and the ground lignite were analyzed for mercury concentration.

The fixed carbon content of the coal is the carbon found in the material which is left after volatile materials are driven off. This differs from the ultimate carbon content of the coal because some carbon is lost in hydrocarbons with the volatiles. Fixed carbon is used as an estimate of the amount of coke that will be yielded from a sample of ...

Torrefaction is a thermal conversion method of biomass used to produce a highquality solid biofuel that can be used for combustion, gasification, and additional nonenergyrelated applications. Torrefied biomass has numerous advantages above today's standard biomass fuels like log wood, wood chips, and white wood pellets (WWPs). This is known and promoted for long, and has been proven in ...

Fineness is an indicator of the quality of the pulverizer action. 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% ...

Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh ( mm) and 99 % will pass through 50 mesh ( mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.
