Abstract
The exergy analysis of boiler combustion performance comparing different fuels is presented, taking into account the combustion modification effects on efficiency and emissions. Comparisons are made between the exergy method and the first law method. It is found that flame and flue gas temperature have a strong influence on the combustion efficiency and boiler emissions. It is also found that oil fuel has the highest combustion efficiency. Gas is the second but it has the cleanest emission. Coal is the worst fuel on both counts. Finally, optimization is made among the combustion modification methods using the exergy analysis. The excess air method is found to be the best method of improvement.
