Dec 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?Get Price

Due to the rising cost of chemical treatment, it is proposed that a pressurised deaerator be installed, operating at 0.2 bar g to raise the feedwater temperature to 105°C, reducing the solubility of oxygen to quantities typically measured in parts per billion. Steam, produced in the boiler at 10 bar g, is to be used as the heating agent.Get Price
