A huge quantity of ash is produced in the central station, sometimes as much as 10 to 20% of the total quantity of coal burnt in a day. Therefore hundreds of tonnes of ash may have to be handled every day in large power plants. Handling of ash includes: 1. Its removal from the furnace. 2. …
It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3 (1,000 ft3) of air to form an explosive mixture. Since a large boiler burns over 40 kg (88 lbs) or more of coal per second, the safe burning of pulverised coal necessitates strict adherence to planned operating procedures.
