Why 'wet coal' Causes Problems for Power Generation . · The problem is when coal arrives at the mill as mud, it cannot be moved by the blowers, much like a blocked fuel injector on a modern-day car engine which has to atomise the fuel before it can combust and create power.
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. "In other words, if the total moisture content becomes too high, the amount of heat energy required to evaporate the moisture is greater than the boiler design allows.
Wet coal and other materials can create complications when being transported or processed. Although they may appear to be minor nuisances, the problems, can slow down production and lead to revenue loss. The ability to process coal to produce electricity is dependent upon proper flow of material, which can be restricted by wet coal.
