The type of bottom ash or boiler slag produced depends on the type of furnace. Bottom Ash The most common type of coal-burning furnace in the electric utility industry is the dry bottom pulverized coal boiler.
As an example consider these facts for typical coal fired power plant of capacity 500 MW. Around 2 million tons of coal will be required each year to produce the continuous power. Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in an hour is delivered by air fans into the furnace.
A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines which turn generators.
