Influence of Air Distribution Modes on Boiler Efficiency

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
