Abstract

The boiler (1) is fired by a burner (2) for liquid or gas fuels. The escaping flue gases pass from the combustion chamber (5) between the walls of outer and inner water-cooled heat exchangers (6, 12), thence past the outside of the combustion chamber. Before they reach the regions between the heat exchangers, the flue gases first circulate in another heat-exchanging space (15) inside the inner exchanger and then, a portion of the flue gases is returned to the burner flame roots through openings (4) in the flame tube (3). The heat-exchanging spaces have devices to increase turbulence like seams, rings, disks, etc.
