Natural Gas Fired Boilers

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

Principles of ultra-low nitrogen burner boilers

2. Precautions for low-nitrogen transformation of gas boilers. In order to help users reduce the cost of low-nitrogen transformation, users can transform their existing gas-fired boilers into ultra-low-nitrogen boilers. The furnace size of the boiler undergoing low-nitrogen transformation needs to meet the transformation requirements.
