Dec 13, 2011 Boilers for steam generation in power plants and process industries use coal as fuel. The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined. Coal is pulverized before firing for achieving a stable and efficient combustion. Many types of pulverizers are used in boilers by different designers.
Coal is delivered to the plant via road, rail or ship, and deposited in a coal yard.Stacker reclaimers are used to gather coal and deposit it into hoppers, the hoppers then feed flatbed conveyors.Conveyors transport the coal from the coal yard to day silos within the main power station building. Each day silo contains enough coal for a set period of time when the power station is fully loaded ...
type coal pulverizer. In this design the grinding rolls are stationary, while the ring or bowl, as it is sometimes called is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe ...
