D. Natural gas (approximated as propyne (C3H4)) is used to provide the energy in the boiler of a steam power plant to add energy to the working fluid (water). The operators have elected to provide 20% excess air to the combustor. The C3H4 enters at standard conditions, 25°C and 1 atm, and the air is preheated to 157°C and 1 atm. The combustion gases leave the boiler at 207°C. Assuming complete combustion occurs with water leaving as a vapor and negligible energy loss to the surroundings, determine the energy transferred to the steam per kmol of propyne. The enthalpy of formation of C3H4 = +185,000 kJ/kmol. C3H4 how many kmol of N₂ per kmol of C3H4 enter the combustor?_ what is the enthalpy of the reactant charge per kmol of C3H4? _kmol N₂/kmol kJ/kmol of C3H4 D.
