Jan 25, 2018· Introduction to Coal handling plant. In a coal based thermal power plant, the initial process in the power generation is "Coal Handling".So in this article i will discuss the overall processes carried out at a Coal Handling plant in a coal based thermal power generating station.

Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse.

Thermal Power Station process flowchart and diagram. The fuel is transported from mines via trains to the fuel storage facility in a power plant. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers.The fuel is then fed to the boiler generating a large amount of combustion heat.
