1. A gaseous fuel mixture with a specified molar analysis burns completely with moist air to form gaseous products as shown in Fig. P13.20. Determine the dew point temperature of the products, in 8C.
2. The gas driven off when low-grade coal is burned with insufficient air for complete combustion is known as producer gas. A particular producer gas has the following volumetric analysis: 3.8% CH4, 0.1% C2H6, 4.8% CO2, 11.7% H2, 0.6% O2, 23.2% CO, and the remainder N2, Determine, for complete combustion with the theoretical amount of air
(a) the molar analysis of the dry products of combustion.
(b) the amount of water vapor condensed, in lbmol/lbmol of producer gas, if the products are cooled to 708F at a constant pressure of 1 atm.
