An experimental lean-burn steady-flow combustion process has been designed to use

An experimental lean-burn steady-flow combustion process has been designed to use bio-butanol as the fuel (C4H100). The liquid fuel enters the combustion chamber at 25C and 1 atm, the air enters at 37C and 1 atm. An analysis of the emissions, while running under steady-state conditions, has given the following results on a dry volumetric basis: 12.96% CO2 0.69% CO 2.13% O2 0.17NO a) Show the stoichiometric reaction scheme for the combustion of bio- butanol (C4H100). [4 marks] b) Determine the actual reaction scheme from the emission analysis provided. [4 marks] c) Determine the air-fuel ratio of the actual reaction scheme. [3 marks] The operating condition of the system is changed so that the following reaction scheme is produced C4H100+ 7(O2 + 3.76N2) 4CO2 + 5H20 + 102 + 26.32N2 It is observed that 2,238,171 kJ of heat is lost from the combustion chamber per kmol of bio-butanol. d) Assuming an exhaust pressure of 150 kPa, determine the dew point temperature [K] of the combustion products in this new reaction.
