Chemical Engineering Question
100 mol/minute of propane gas is burned completely in acontinuous reactor with air to form carbon dioxide and water.Develop an Excel spreadsheet to calculate the adiabatic flametemperature if the gasses are fed at 30oC, 1atm for the followingcases:
% Excess Air = 0%, +10%, +25%, +50%, +75%, +100%, +150%,+200%
Use heat capacity data from Table B.2 for all components in thecombustion reaction.Turn in a hard copy of the Excel spreadsheet aswell as a plot of adiabatic flame temperature vs.% excess air.

propane C3H8 combustion can be represened as C3H8 5O2 3CO2 4H2O the probelm can be divided into two parts one mass balance and the second energy balance mass balance 1 mole of C3H8 requires 5 moles of oxygen and gives 3 moles of CO2 and 4 moles of H2O moles of air 1021 since air contains 21 O2 and 79 N2 476 moles this data can be used for calculation of air flow rate See Answer
