<p>A base, for coupling three main parts of a combustion chamber, is produced by direct connection of the lower and upper edge of the combustion cylinder with corresp. insertion parts on the base and the collection pipe. The base and collection pipe peripheries have a conspicuous multi-cornered form, and coincide with a proportion which is higher than for the cylinder fitment between these two parts. On the vertically extending sides andjoining each of the base sides with the corresp. side of the collection pipe, are flat light panels (18) which form an outer prismatic casing with open corners, which are closed by vertical venting grids (21). These grids are covered by the side spaces located between the casing panels. These panels and the vertical grids are maintained without direct contact with the combustion cylinder.</p> |
