The ECOMAX
®
burner unit is composed of four modules:
burner housing, recuperator, air guide tube and gas insert.
The modular design facilitates adapting the burners to the
respective application or integrating them into an existing
furnace system. Maintenance and repair times are reduced,
and existing furnace installations can easily be converted.
3 .1 Burner housing
The burner housing accomodates the connections for the
combustion air, gas, cooling air and flue gas channelling. It
also secures the burner insert. It is made of cast aluminium,
which means it has a low weight. The housing has a double-
wall design. The combustion air is fed into the burner via the
outer annular gap. This cools the burner housing und reduces
emissions.
3 .2 Recuperator
All-ceramic
The surface of the all-ceramic recuperator, which is made
of SiSiC for high thermal stress, is burled in order to achieve
high efficiency.
Cast steel
The ribs on the cast steel recuperator offer a large surface area,
allowing it to achieve high efficiency even at low temperatures.
Flat tube
The flat tube recuperator has a smooth surface. It is a cost-
effective alternative at a lower efficiency level and is suitable
for lower application temperatures.
