Abstract

The combustion chamber (1) in a gas burner assembly has toughened convector, (6,7), with a shape-elastic right angled rib structure, in front of the thermal insulation material (5) at the chamber walls. In operation, the coolant air streams (L,L') can flow through them, to reduce the temp. at the insulation to 700-800 degrees C. The rib structure is formed by folding pleats in a steel plate. The insulation material is a micro-pore soft ceramic.
