Question

Perform stoichiometric combustion calculations for Appalachian low-Sulphur and Wyoming PRB coals from the Coals.xls spreadsheet. For the excess air coefficient E = 20% for the Appalachian coal, and E=15% for the Wyoming PRB coal, use the mole method to determine: -Composition of flue gas on wet volumetric basis. - Air-to-fuel ratio (A/F) 1. Perform calculations assuming complete combustion (no UC and CO), and wet air containing having 50% relative humidity (RH) at 77°F and ambient pressure. Tabulate and comment the results
