Gaseous propane (C 3 H 8 ) is burned in a steady-flow, constant-pressure process at 100 kPa

Question:

Gaseous propane (C₃H₈) is burned in a steady-flow, constant-pressure process at 100 kPa with 200 percent theoretical air. During the combustion process, 90 percent of the carbon in the fuel is converted to CO₂ and 10 percent is converted to CO. Determine

(a) The balanced combustion equation

(b) The dew-point temperature of the products, in °C

(c) The heat transfer from the combustion chamber, in kJ, after 100 kmol of fuel are burned when the reactants enter the combustion chamber at 25°C and the products are cooled to 25°C.

he, kJ/kmol - 103,850 - 393,520 - 110,530 - 241,820 - 285,830 C,H,(g) CO, CO H,O(g) H,O(1)
