Katalytischer Brenner

The heat transmission from the at least one catalytic converter (5) to the heat-absorbent wall parts (2) is produced from radiation. At least one of the wall parts has protuberances between which part of the catalytic converter matching the shape of the protuberances fits. The wall parts have ducts (3) for coolant. The parts of the catalytic converter between the protuberances are joined by a transverse part of the catalytic converter, of are separate segments. The plate forming the wall part has passages (4) through for a mixture of fuel and air fed to the side of the plate facing the protuberances. the surface of the wall part facing the catalytic converter is coated with a layer (6) absorbing infra-red rays. ADVANTAGE - The power density of the catalytic burner is improved.
