Liquefied butane(c4h10)is supplied to the
combustion chamber at a mass flow rate of
2kg/min and burned with excess air of 25°C
and 140%.
The combustion gas temperature was
1400K, and when the exhaust gas was
measured at 2 atmospheres,
CO2,H2O,CO,02 and N2 were detected.
(a) Find the equilibrium condition of the
grnerated gas,
(b) the heat transfer rate from the
combustion chamber.
(However, CO is grnerated by thermal
dissociation of 2% of Co2 by a reaction
formula CO2->CO+0.502)
(consider whether it is okay to ignore NO in
combustion gas.)
(However, the LHV of C4H10 is
45370KJ/KG.)
3.11 Liquefied butane (CaHo is supplied to the combustion chamber at a mass flow rate of 2 kg/min and burned
with excess air of 25°C and 140%. The combustion gas temperature was I 400 K, and when the exhaust gas
was measured at 2 atmospheres, C0, H,0 and Co, 0,and N,were detected. (a) Find the equilibrium
condition of the generated gas, (b) the heat transfer rate from the combustion chamber. However, Co is
generated by thermal dissociation of 2% of CO, by a reaction formula of CO, cot!0, And consider
whether it is okay to ignore NO in combustion gas. However, the LHV of H, is 45,370 kJ/kg.
