High Marnham Power Station - Wikipedia

Coal was fed from overhead bunkers by speed-regulated drum feeders to the mills and crushed to fine dust by three 7.5 ton roller drums per mill, then blown into the wind boxes through pipework and the PF nozzles. Combustion air was delivered by two forced draught fans located above the coal bunkers, taking warm air from above the boiler roof casing and discharging it though rotating heat,,,,,,
