Oct 07, 2019· Along with moisture and ash contents, the percentage of volatile matter in a coal sample is needed to calculate the fixedcarbon content of a coal. Many electric utilities prefer coals within a narrow range of volatile matter (25 to 35 percent) for optimal flame stability in the boiler (Thomas, 1992). Highvolatile matter may also be associated ...
Nov 01, 2009· The velocity is a function of coal piping geometry, coal type, moisture content, coal fineness and more. The value is important because at lower velocities, coal flow cannot be sustained and coal ...
Calculations are performed for short periods of time ( 1 h), provided that it is possible to change the fineness of the coal by controlling the angle of the classifier guide vanes. Therefore, the optimum value, adapted to the current parameters, may be easily set. A program was created in MS Excel to perform the optimization calculations.

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also ...
