The blowing and the scavenging tube are installed in the gas or air heater and are axially shiftable mounted – the blowing element remains in the flue gas pass.
During the blowing process the blowing and the scavenging tube continue to move further into the heater.
On reaching the front-side end position the direction of movement changes and the lance tube returns to its starting position.
Special features
integrated stop valve with adjustable throttle disc for comfortable adjustment of the blowing pressure
