Flue gas from a sugar mill furnace burning bagasse fibre in air contains 8.35% CO2, 15.5% H2O, 0.55% O2 and 75.6%N2. 130 kmol/min of the flue gas exits the furnace at 1300 C and 1atm and is used to generate steam in an adiabatic boiler (i.e. well-insulated heat exchanger). After exchanging heat with the steam, the flue gas leaves the boiler at 350 C and 1atm. Saturated liquid water at 75 C enters the adiabatic boiler tubes where it is heated by the flue gas to its exit conditions: saturated steam at 4.8 bar pressure. Calculate the mass flow rate of water/steam leaving the boiler.

1. Exhaust gas at 400 C and 1 bar from i engines flows at the rate of 125 mol s into a waste-heat boiler where saturated steam in generated at a pressure of 1200 kPa. Water enters the boiler at 20 C (Ta) and the exhaust gases are cooled to within 10°C of the steam temperature. The heat capacity of the exhaust gases is C/R-3.341.12x10 T/K. The steam flows into an adiabatic turbine and exhausts at a pressure of 25...
