Influence of Air Distribution Modes on Boiler Efficiency

Article Preview

Abstract:

The influence of air distribution modes on boiler efficiency was researched by combustion adjustment tests. Boiler efficiency variation was studied by changing factors such as oxygen content, upper tertiary air, over fire air and secondary air distribution modes. Boiler efficiency reached maximum under 3.9% design oxygen content. Carbon content in fly ash increased as upper tertiary air ratio, consequently boiler efficiency declined. Average furnace flame temperature decreased inversely as over fire air baffle opening, and boiler efficiency variation was small. Under different conditions, boiler efficiency varied within 1.12%. Beam waist air distribution mode obtained the highest boiler efficiency.
