Why is a burner purge necessary before ignition


Preventing explosions: During burner operation, unburned fuel may accumulate in the furnace or around the burner.


If this fuel mixes with air to form a combustible mixture, it could explode when exposed to an open flame.


Purge uses airflow to remove this accumulated fuel, reducing the concentration of the combustible mixture to below the explosion limit, thereby eliminating the explosion hazard.


Removing debris: After burner installation, maintenance, or extended operation, dust, rust, and other debris may accumulate in the furnace.


Purge removes this debris, preventing it from entering burner components during combustion, affecting combustion efficiency or causing damage such as wear and blockage.


Ensuring combustion efficiency: Purge creates a stable air flow field in the furnace, creating optimal conditions for complete combustion of the fuel after ignition.


A stable air flow promotes even mixing of fuel and air, resulting in more complete and stable combustion, improved combustion efficiency, and reduced production of incomplete combustion products, such as carbon monoxide and other harmful gases.


Ensuring safe operation: The purge process allows you to inspect the burner's ventilation system, valves, and other components to ensure proper function.


If problems such as poor ventilation or valve malfunction are discovered during the purge process, they can be repaired or replaced promptly to avoid safety issues after ignition and ensure safe and stable burner operation.
