Step 1
Filling compressed air into the pneumatic pressure chamber

Step 2
Filling fuel gas into the main pressure chamber

Step 3
Filling compressed air into the main pressure chamber

Step 4
Igniting the gas mixture

Step 5

• The pneumatic actuator opens when a defined pressure is reached. The compressed heated air in the main pressure chamber escapes within some milli seconds into the boiler.
• This escaping fluegasreaches supersonic speed and creates the powerwave.
• This wave spreads in all direction within the boiler and removes the dust and slagging from the heat exchanger
