Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage which is used when coal supply is unavailable.
excess air. Station service power will decrease with drier coal due to a decrease in fan power and mill power. The combination of all these effects caused by firing drier coal will result in an improvement in boiler efficiency and unit heat rate, primarily due to the lower stack loss and lower station service power.
