Estimating the term…
Provided is a silo combustion chamber comprising a vertically extending flame tube that can be lit from above and through which circulation takes place in a downward motion, the outer surface of the flame tube being provided with a plurality of cooling fluid supply openings and the inside thereof being lined with ceramic heat shield elements, the lowest heat shield elements being supported on a metal supporting ring; a conically tapered mixing tube arranged downstream from the flame tube, into which the lower region of the flame tube is set; and an outer housing that surrounds the flame tube and the mixing tube, forming an annular supply channel, the lowest heat shield elements completely covering the radially inwardly oriented surfaces of the supporting ring. Also provided is a method for retrofitting a silo combustion chamber.
A silo combustion chamber comprising
A method for retrofitting a silo combustion chamber having a vertically extending flame tube with downward throughflow which can be fired from above, the casing surface of which is provided with a plurality of cooling fluid supply openings and is lined internally with ceramic heat shield elements, wherein the lowest heat shield elements rest on a metallic supporting ring which has a circumferential support face extending substantially horizontally, on which the lowest heat shield elements each rest with a contact face and which is provided with a plurality of radially extending cooling fluid bores, a conically tapered mixing tube arranged downstream of the flame tube, into which the lower region of the flame tube is set, and an outer housing which surrounds the flame tube and the mixing tube, forming an annular supply channel, comprising the steps:
