Combustion Efficiency and Excess Air

Boiler heat losses by irradiation and convection from the boiler casting into the nearby the boiler house (Patro, 2016): (3.71) HL 6 = 0.548 × [ ( T s / 55.55 ) 4 − ( T a / 55.55 ) 4 ] + 1.957 × ( T s − T a ) 1.25 × [ ( 196.85 × V m + 68.9 ) / 68.9 ]

CHAPTER 3 COMBUSTION CALCULATION

Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.

steam in the boiler. As the temperature of the flue gas leaving a boiler typically ranges from 150 to 250 1C, about10–30%of the heat energy is lost through it. A typical heat balance in a boiler is shown in Fig. 1. Since most of the heat losses from the boiler appear as heat in the flue gas, the recovery of this heat can result in substantial energy saving .This indicates [16]
