Two boilers are operating steadily on 91000 kg of coal contained in a bunker. One boiler is producing 1591 kg of steam per hour at 1.2 factor of evaporation and an efficiency of 65% and another boiler produces 1364 kg of steam per hour at 1.15 factor for evaporation and efficiency of 60%. How many hours will coal in the bunker run the boilers if the heating value of coal is 7590 kcal/kg?
