A power plant uses either a forced draft fan or induced draft fan to enhance flows through the steam generator assume the pressure losses are 60 inches of water and the efficiencies of the blowers are 0.7. The flow of air through the F-draft fan is at 60 degrees Celsius and the flow through the I-draft fan is 300 degrees Celsius. Assume there is a 2% in leakage for the I-draft blower. The specific heat for the air through the F-draft fan is 0.24 Btu per pound mass degree Rankine and for the flue it is 0.243. Assume the fuel burned is 100 % C at 92,000-pound mass per hour in 125% theoretical air. Calculate the power of each blower if they are used alone in Megawatts and horsepower. A high quality coal is being burned in a power plant. Determine the temperature of the flue that one must stay above to avoid the dew point. The pressure at the I-draft fan is 1 psi. Assume the coal is burned in 10% excess air. The composition of the coal is 81.9% C; 2.9 % H2; 0.7% S and O2 each; 1.3% N2; and 4.5% H2O.
