 Question = A 65000 kW steam power station used coal of calorific value 15000 kcal/ kg . If the coal consumption per kWh is 0.5 kg and the load factor of the station is 40 % . Calculate (1) coal consumption per day ? 

Solution = steam power station = 65000 kW , coal calorific value = 15000 kcal/ kg , per kWh coal consumption = 05 kg , load factor = 40 % , 

Formula , 

» coal consumption per day = unit generated/day = maximum demand × L.F × hour in a day ,  

» 65000 × 0.4 × 24 = 624000 kWh , 

» 1 kWh = 0.5 kg ,  = तो 624000 kwh में होगा 624000 kWh × 0.5 kg = 312000 kg , or , 312 tons , answer ✓
