Pulverizing Mills | Thermal Power Plant
Pulverizing Mills. Each of the six units at Drax has ten pulverising fuel mills, each capable of pulverising 36 tonnes of coal per hour. Inside the mills, ten giant hollow steel balls, each tonnes in weight and approximately 730 millimetres in diameter, crush the coal into a fine powder. Crushing the coal into a fine powder makes it easier ...
Draught Fans Used in Thermal Power Plants
· In power plants, where coal is used as fuel for combustion, FD fans are used as primary and secondary air fans to regulate proper combustion and maximize the fuel efficiency of the process. A typical FD fan arrangement uses inlet and outlet dampers to control and maintain the required air pressure inside the system.
