The effects of coal moisture content on unit performance are presented in Figures 1 to 3. Figure 1 shows the reduction in total air, flue gas and coal flow rates as fuel moisture content is reduced. Corresponding reductions in fan and mill power are presented in Figure 2.
Preparation of materials: The coal was sundried for three days to reduce its moisture content and was broken into small particles using hammer. It was then ground into fine powder using electric milling machine and sieved to obtain coal of particle size of 1 mm in diameter.
Testing also yields important information about the size reduction process such as particle size distribution before and after crushing, moisture content (which changes during crushing, affecting the material's handling characteristics), power consumption, and estimated wear cost (in terms of how frequently metal parts must be replaced).
Moisture content is determined by heating an airdried coal sample at 105–110 °C (221–230 °F) under specified conditions until a constant weight is obtained. In general, the moisture content increases with decreasing rank and ranges from 1 to 40 percent for the various ranks of coal.
