Calculate the annual fuel costs for 10MW power plants based on the following cycles. The fuel is hybrid poplar available at $48/Mg at 20% moisture. Hint: The energy required to evaporate the moisture of the wood is incorporated into the facility efficiency. The percent moisture affects how much biomass to purchase. a. Conventional steam power plant with a heat rate of 14,000 BTU/kWh. b. Integrated gasification/combined cycle (IGCC). The gasification of the biomass is 85% efficient. The Brayton and Rankine cycles operate at 30% and 25% efficiency, respectively, due to the small plant size. Hint: Use the combined cycled efficiency equation for the combined efficiency of the Brayton and Rankine cycles. Hint: For the overall efficiency, multiply the gasification efficiency by the combined efficiency. c. Why is the Brayton cycle the topping cycle and the Rankine cycle the bottoming cycle
