Abstract

The heating boiler is intended for burning liquid or gaseous fuels and consists of a water-bearing housing (1), in which a firebox (3) fitted with the burner (2) is arranged, from which firebox a number of waste gas flues (4), which extend through the water-bearing housing (1), lead to the waste gas collecting chamber (5), in which flues waste gas displacement members (6) are arranged for the purpose of forming elongate annular cylindrical waste gas flues (7). In order to be able, on such a boiler, to bring about waste gas recycling using the most simple means, the heating boiler is according to the invention designed in such a manner that, in at least one of the waste gas flues (4), the displacement member (6) is designed as a waste gas return pipe (20) which opens freely in the waste gas collecting chamber (5) and the other end (8) of which is connected to a connection opening (9) of the firebox closure (10) and, from there, is connected to the burner (2). <IMAGE>
