Pure ethane (C2H6) at a rate of 100 mol/s is burned using stoichiometric air in a furnace to generate heat. The ethane combustion reaction follows the equation: C2H6+ 3.502 -> 2CO2 + 3H2O. Burning occurs perfectly. The flow temperature of ethane gas and air is 250C, while chimney gas temperature 2004. A. Calculate the heat (Q) produced (transferred) from the combustion of the ethane gas. B. If the heat (Q) of combustion is used to produce saturated steam (saturated steam) 40 bar, calculate the mass flow rate of steam that can be produced. Boiler feed water with 40 bar pressure and 30 C has enthalpy (H) of 125.7 kJ/ kg and enthalpy value of steam (H) of 2800 kJ/kg F1 = 100 mol/s C2H6 = 100% T1=25 Ⓡ C Q=? Combustion Process F2 = ?mol/s 102= 21% - mol N2=79% - mol T2=250C F3 = ? mol/s N2=?% - mol CO2 = ?% - mol H2O = ?% - mol T3-2000C
