Why does wet coal burn better?
When high moisture coals are burned in utility boilers, about 7 percent of the fuel heat input is used to evaporate fuel moisture. This results in higher fuel flow, higher stack flue gas flow, higher parasitic power, lower plant efficiency, and higher mill maintenance costs compared to low- moisture coals.
Why do they keep coal wet?
“Due to the heat in the boiler, the coal particles combust and burn to generate heat to turn water into steam.” … When the coal is removed from the mills through a blast of hot air, if the coal is too wet, the drying out is ineffective and has a negative effect on the combustion of coal.
Do you need to keep coal dry?
Although coal is not as susceptible to moisture as firewood is, it is still important to ensure that it remains dry. After all, wet coal is notoriously difficult to burn because it struggles to hold a flame and the excess moisture means that the fire output is very low in quality because a lot of energy is wasted.
Does wet coal burn better?

Can you burn coal if it’s wet?
