Two boilers are operating steadily on 91,000 kg of coal contained in a bunker. One boiler is producing 1,591 kg of steam per hour at 1.2 factor of evaporator and an efficiency of 65% and another boiler produced 1,364 kg of steam per hour at 1.15 factor of evaporation and an efficiency of 60%. How many hours will the coal in the bunker run the boilers if the heating value of coal is 7,590 kCal/kg? 230.8 O 118.2 94.54 O 184.6 O 147.7
