MD2533B1 - Radiation burner - Google Patents

Abstract

The invention relates to the heat engineering, in particular to burning devices of the thermotechnical sets. The radiation burner contains a cylindrical blind casing with smoke flue, a gas pipe with branch pipes for inlet of the gas and of the primary air coaxially installed therein, a secondary air pipe and a flame tube, into the cavity of which there is placed the nozzle of the secondary air pipe. Novelty consists in that the flame tube, the wall edges of which from both ends are made flanged inside, has one end installed in bearing balls of thermostable material, placed into an annular groove, made onto the lateral side of the centring cylindrical prominence, placed onto the blind end inside the casing, and the other one - in the bearing balls, placed in the longitudinal grooves, made outside the wall of the secondary air pipe inclined towards the nozzle. Into the wall of the secondary air pipe, in the ball placement region, there are executed through holes. Claims: 1Fig.: 1
