Abstract

A heating system burns liquid or gaseous fuel in a ceramic burner tube (1) which discharges to an overlapping and supporting metal pipe (2). The overlapping zone between the two pipes has a series of radial apertures (3, 3') for circulating effluent gases. The holes (3, 3') in each pipe correspond with those in the other pipe. The holes in the metal pipe are smaller and more precisely positioned than those in the ceramic pipe.
