To supply heated air to a house, a high-efficiency gas furnace burns gaseous propane (C3H8) with a combustion efficiency of 96 percent. Both the fuel and 40 percent excess air are supplied to the combustion chamber at 25C and 100 kPa, and the combustion is complete. Because this is a high-efficiency furnace, the product gases are cooled to 40C and 100 kPa before leaving the furnace. To maintain the house at the desired temperature, a heat transfer rate of 31,650 kJ/h is required from the furnace. Determine the volume of water condensed from the product gases per day, in Litre/day.

Propane burns with 15% excess air. Before the propane-air mixture enters the burner, air preheats from 32 F to 575 F. Determine the requirements of the preheater (BTU / h) if the amount of propane fed to the burner is 1.35x105 SCFH (standard cubic feet per hour) Note: In this case, take standard conditions in the natural gas industry, such as 60 F and 1 atm. Report: a) Flow diagram of the complete process and its table of material balance...

In a closed combustion vessel, propane (C3H8) and air are mixed at equivalence ratio of 1.11, temperature of 298 K, and pressure of 1 bar. The mixture is burned to produce solely CO2, CO, H2O, and N2. The heat rejected from the vessel is 820 MJ/kmol of fuel. What are the final temperature and final pressure of the mixture? Since neither O2 nor H2 is present in the burned gas, dissociation can be neglected.
