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.

Retrofitting coal‐fired power plants with biomass co

It can be seen that small power plants (no. 1–5) are more suitable for biomass‐coal co‐firing. For 700 MW power plants, no. 8 and no. 9 are more suitable for retrofitting than no. 6 and no. 7 power plants. With the increase of installed capacity, CCS technology can achieve better emission reduction benefits and economy of scale.
