Question:
Reconsider Prob. 15–82. The combustion products are expanded in an isentropic turbine to 140 kPa. Calculate the work produced by this turbine in kJ/kg fuel.
Data From Q#82:
A large railroad has experimented with burning powdered coal in a gas turbine combustor. Fifty percent excess air was introduced to the combustor at 1380 kPa and 127°C while the powdered coal was injected at 25°C. The combustion was adiabatic and at constant pressure. Based on a coal from Colorado that has an ultimate analysis (by mass) of 79.61 percent C, 4.66 percent H2, 4.76 percent O2, 1.83 percent N2, 0.52 percent S, and 8.62 percent ash (non combustibles), what is the estimated temperature of the combustion products? Neglect the effect of the sulfur in the energy balance.
