A fire tube boiler develops 75 metric tons of steam at a pressure of 12.5 mpa and a temperature of 680°C for a period of 8 hours. The feedwater temperature is maintained at 95°C. If the boiler efficiency is 87.5%, find the average amount of coal burned in kg per hour if its heating value is 12,500 Kcal/kg.
