Consider a 800 mw coal and corn stover co-fired rankine cycle power plant with a capacity factor of 86.0% and an availability of 97.0%. the coal used to fuel the power plant has a carbon content of 54.0% (wt), a higher heating value of 8800 btu/lbm, and costs $46.00/ton. the plant is considering co-firing coal with 10% corn stover based on input energy. the corn stover consists of 30.0% carbon (wt) and has a higher heating value of 6000 btu/lbm, and costs $62.00/ton. the corn stover is considered a carbon neutral fuel. the plant has a heat rate of 9400 btu/kwh. a. how many tons of coal are needed annually to fuel the co-fired power plant (106 t/y)? b. how many tons of corn stover are needed annually to fuel the co-fired power plant (t/y)? c. what is the annual fuel cost of the co-fired power plant (106 $/y)? d. how many metric tons of co2 are generated annually by the power plant (10% mg/y)? e. how many metric tons of co2 are generated per mwh of electricity output (mg/mwh)?
