Chimney height = 90m
Feed water = 1400 kg/hr
Temperature of feed water = 30ºC
Boiler working pressure of dry & saturated steam = 20 bar
Coal used = 200 kg/hr
Calorific value of coal = 28000 kJ/kg
Flue gas temp. in chimney = 300ºC
Flue gas formed = 18 kg/kg of coal burnt
Ambient temp. = 32ºC
Cp of products of combination = 1.028 Kj/Kg.K
Find i) Thermal efficiency. ii) Equivalent evaporation. iii) Heat carried away by flue gases.
