CERAMAT
GAS
BURNER
FP
FOR GAS-FIRED
BOILERS AND
WATER HEATERS
CHARACTERISTICS
• High specific load: the combination of
a highly permeable burner material and
perforations supports specific loads of
up to 30 Kw/dm 2 with a perfectly stable
flame for all the limit gases. This makes
it possible to design small, compact
burners and systems.
• Wide modulation range: the
material’s flame stability and
temperature resistance support a
modulation range of 1:30. Star-stop
emissions due to frequent on-off cycles
can be substantially reduced, resulting
in low emissions and easily modulated
water temperature for combination
boilers.
• Electrical conductivity: SiC coating
makes Ceramat burner conductive.
Electricity can pass through the material,
being this a great advantage for the
control of the flame detection. The
ionization signal is very good, similar to a
metal burner.
• Wide radiation range: this ensures low
NOx emissions at low flame temperatures.
• Stable combustion: with all common
gas types and limit gases, burners ignite
and operate safely with Ceramat Gas
Burner FP.
• Load-bearing, self-supporting mat
with thermal expansion: Ceramat Gas
Burner FP makes it possible to design
simple, cost-efficient burners.
• Variable geometry: for optimal heat
transfer, the flat burner surface can be
fully adapted to the heating system.
• Variable perforation: the perforation
pattern of the burner surface is
customizable and determined as a
function of system requirements.
MAXIMUM OUTPUT,
MINIMAL SPACE
Ceramat Gas Burner FP is a highly
efficient burner medium made of
silicon carbide coated ceramic fibers
solidly welded together to form a
self-supporting mat structure. This
highly permeable, homogeneous,
perforated burner mat is ideally suited
for use in radiant and blue-flame gas
burners in heating boilers. Its main
advantages are high performance,
a wide modulation range and low
emissions. In addition, it allows
compact burner design.
