Frequently Asked Questions about Pulverizer What is a pulverizing machine used for? A pulverizing machine breaks down large chunks of material into smaller, finer particles. Coal power plants use it to grind coal into fine particles. This happens before combustion in steam-generating furnaces.
Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the process works as well as …
Feeder speed demand minimum, Pulverizer ON, pulverizer outlet temp > 130 O F, HAG open and no MFT are the important conditions required to give the feeder start command from FSSS. In case of pulveriser power high, bowl DP High or feeder OFF command, feeder speed demand is driven to minimum. Release feeder to Auto Signal is also coming from FSSS.
Working Principle of a Thermal Plant. The working fluid is water and steam. This is called feed water and steam cycle.
