### 1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

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. The flue gas leaves the boiler at 300oC (all the water formed will be vapour). In addition, a

### CHAPTER 4 GAS BURNER CONVERSION

•Flue gas analysis –Oxygen or CO measurement is recommended to check whether proper air/gas ratio and firing is obtained –This is also for safety and furnace/boiler efficiency analysis •Pressure measurements –Pressure, both air and gas, should be measured at suitable points to check the firing condition and also their maintenance

*As an example: A natural gas fired boiler's flue gas was measured on a wet basis to be 6% O2 and 9% CO2, the corrections would be: % O2, dry basis = %, wet basis x F = 6% x 1.15 = 6.9% % CO2, dry basis = %, wet basis x F = 9% x 1.22 = 10.98% So to determine dry flue gas loss, one needs

### Material Considerations in Boiler Design

The losses caused by the sensible heat of flue gases can be calculated as: m& i φ L 3 = m& fuel ⋅ ∑ ⋅ hi (11) i m& fuel where m& fuel is the fuel mass flow [kg/s], m& i the mass flow of a flue gas component, and hi the specific enthalpy of a flue gas component (e.g. CO2) [kJ/kg].

### Boiler Efficiency - an overview | ScienceDirect Topics

The output of a 1 ton boiler is 700,000 kcal, and so on. The output of a 10 ton boiler is 7 million kcal. Second, the fuel consumption calculation formula. Fuel consumption = boiler output ÷ fuel calorific value ÷ boiler thermal efficiency.
