Mill Bowl mills are employed to pulverize the precrushed raw coal to the required fineness before it is admitted into the boiler furnace for combustion. The mill output can be easily varied, as per the turndown ratio from its minimum to maximum load. Crushed raw coal at a controlled rate is fed into the revolving bowl of the Bowl Mill. Centrifugal force feeds the coal uniformly ...

Tags. An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside aircooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC. In thermal power plants (T), the steam from the turbine exhaust flows into the ACC where condensation occurs.
