Example 3.1. A chain grate stoker is used to burn bituminous cool having 10% moisture and 10% ash. The higher calorific value of coal is 7000 kcal/kg. The steam generator produces steam at the rate of 10,000 kg per hour. It uses 600 kcal to evaporate 1 kg of feed water entering the boiler and super heat it to the final temperature, calculate the following: (a) Hourly coal supply (6) Grate area (c) Grate length if grate width is 5 metres. Assume overall steam generator efficiency 40%. This seker can burn the coal at the rate of 15 10% kcal per sq. tine!
