An average pulverized-coal power plant has anefficiency of 33%. Suppose a new ultra-supercritical coal plant increases that to 42%. Assume coalburning emits 24.5 kgC/10° kJ. (1 kWh = 3600 kJ ajd 1 metric ton = 10 kg) If CO2 emissions are eventualy taxed at $50 per metric ton, what would the tax savings be for the supercritical plant ($/kW). 24 K9 soal 2t大* 50 1'27K24.589 k - 11.9 KJ 278*10 Krh kwh with n=033 11- 36 05 11-9 0-3 with2-o42 = 28.33 & Ewh 0:42 Saving = 36.05-28.33=7.-72 KWh lf coal that delivers 24x106 kJ of heat per metric ton costs $40/metric ton, what would be the fuel savings for the ultra-supercritical plant ($/kWh)?
