5 Factors Killing Your Industrial Boiler Efficiency & …

Excess Air Effect on Industrial Boiler Efficiency. All combustion burners require some degree of excess air. Excess air is defined as the amount of air in a combustion process greater than the amount theoretically required for complete oxidation. Due to the high content of hydrogen for industrial boilers relying on natural gas, fuel

Combustion efficiency decreases with increasing superficial gas velocity. Combustion efficiency initially increases with increasing excess air level and then decreases. PCFBC boilers achieve higher efficiencies due to smaller and more frequent bubbles, which results in better gas-solid contact. The fuel, usually natural gas, coal gas
