Effect of moisture in coal on station heat rate and fuel

The effects of moisture in coal on the power block (boiler-turbine-generator unit) are decreased in boiler efficiency (Figure 7), decreased overall unit efficiency (increase in heat rate) (Figure 8) and decrease in unit load.. The boiler efficiency decreases due to increase in moisture and the unit heat rate increases. This results in increased cost of generation.

Moisture Correction for Coal Analysis Bright Hub

2020-7-13  The moisture in Coal consists of two parts. One is the moisture held within the molecular structure of the coal called “inherent moisture.” Removal takes place only at temperatures greater than 100 deg C. The second part is the moisture that is on the surface of the coal. This is normally due to the conditions and locations of the mines.

2015-8-15  Figure 1 shows the boiler efficiency with the GCV of the coal. As the coal used with higher GCV, efficiency is increased. Lignite coal with 4300 kcal/kg gives a 77.51% in this boiler, while semi bituminous coal with 5800 kcal/kg gives 80.20% efficiency in this boiler. So as the higher grade coal is used, efficiency will be increase.
