715 Q.2. A boiler delivers 5500 kg of steam/h at a pressure of 750 KN/m² and with a dryness fraction of 0,90. Tehe feed water to the boiler is at a temperature of 41.5 C. The coal used for firing the boiler has a calorific value of 30000 kJ/kg and is used at the rate of 670 kg/h. Find : a) the thermal efficiency of the boiler, b) the equivalent evaporation of the boiler in kg/coal Note; hy = 409.3 kj/kg, hyg = 2055.5 kj/kg, hfw (145)=173,9 kJ/kg 1
