Hauck’s ISER immersion burner represents the latest burner technology for liquid aluminium and zinc heating with high thermal efficiency, durability and reduced
NOx emissions. The design incorporates Hauck’s highly successful SVG
burner technology for excellent turndown capabilities, proven
performance and reliable direct spark ignition.
The ISER operates by conducting the heat of
combustion through the wall of the ceramic immersion tube. Efficient
transfer of available heat is assured through the thermal properties of
the liquid metal in the bath where the tube is placed.
New galvanizing baths using an ISER burner can be
more compact, efficient and allow more accurate process control than
comparative systems. Conventional systems can be redesigned to take an
advantage of this compact heat source.
Thermal shock resistant silicon carbide combustor/recuperator tubes permit long life of ISER burners used in
aluminium filter boxes, die casting holding furnaces, and other
immersion applications.
Careful design of bath equipment can yield
surface area heat inputs up to 8 times greater than with conventional
direct fired equipment. This leads to smaller baths and reduced
structural heat loss.
The use of the immersion burner design assures
that products of combustion are prevented from coming in contact with
the metal. This results in significant reduction of surface oxidation,
dross losses and hydrogen absorption in the bath.
It is possible to achieve very accurate bath
temperature control during processing. This ensures repeatability and
product quality control during the process. Because they are
self-recuperative, ISER burners operate at thermal efficiencies up to
60%, contributing to significant energy savings over direct-fired
burners.
