The Lungs of the Boiler: Inside Combustion Air and Draft Systems

Combustion in an industrial boiler doesn’t happen by fuel alone, the supply and movement of air are just as critical. The combustion air and draft systems form the “lungs” of the boiler, ensuring the burner receives the right amount of oxygen and that combustion gases are safely removed. 

When these systems work properly, boilers burn cleanly, efficiently, and reliably. When they don’t, the result can be flame instability, excessive emissions, fuel waste, or even unsafe operating conditions.

Let’s look at the invisible ingredient every flame depends on, the critical balance driving boiler performance, fine-tuning the flame, and airflow assassins.
