11. Two boilers are operating steadily on 91,000 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 produced 1364 kg of steam per hour at …

Read MoreDec 17, 2017 · A 23.5 kg/s at 5 MPa and 400oC is produced by a steam generator. The feedwater enters economizer at 145oC and leaves at 205oC. The steam leaves the boiler drum with a quality of 98%. The unit consumes 2.75 kg of coal per second as received having an heating value of 25,102 kJ/kg. What would be the overall efficiency of the unit in percent?
