6. a rural iowa community is considering a corn stover-fired 55.0 mw electric power generation plant. assume that the power plant will have a capacity factor 92.0% and an overall efficiency of 27.0% based on the higher heating value of the stover. the land near the proposed plant yields on average 3.60 dry tons of stover per acre annually and 60.0% of the stover can be sustainably harvested. the remaining stover is left on the land to prevent soil erosion and nutrient depletion. the as-received stover contains 23.0% moisture and 6.0% ash. the stover is dried before being used to fuel the power plant. the dry basis higher heating value of the stover is 17.9 mj/kg. a. how much electricity will be delivered annually (mwh/y)?
b. how much fuel will be required to deliver 1 mwh of electricity (kg/mwh)?
c. how much corn stover (dry basis) will be required each year to fuel the power plant (mg/y)?
d. what is the total area of farmland required (ac)?
