Combustion gas
Gas insert
The self recuperative burner ECOMAX
flue gases to preheat the combustion air. The heat exchanger
(recuperator) required for this is part of the burner.
After entering the burner, the combustion air flows in the gap
between the air guide tube and the inside of the recuperator
towards the tip of the burner. Some of this air is fed into the
inside of the burner, where it combusts in the first combustion
stage. The rest of the combustion air flows out through the gap
between the combustion chamber and the recuperator head
at high speed before combustion takes place in the second
combustion stage here. This process means that fewer pol-
lutant emissions are produced.

Combustion chamber
The hot flue gases, flowing in the opposite direction, leave the
furnace chamber on the outside of the recuperator. Heat is ex-
changed between the hot flue gases and the cold combustion
air through the recuperator wall. The burner is directly ignited.
