Abstract
The disclosure relates to an apparatus having a burner and a heat exchanger wherein between a hollow cylinder provided with an end wall and a concentric insert there is formed an annular gap which is free from integers and in which the combustion gases flow from the burner to the outlet. The object is to provide apparatus which permits a starting phase with a pure flame and without pulsations and wherein at the same time the lower power limit can be considerably reduced. This object is achieved by providing in the end of the insert facing the end wall with an annular end wall and a central burner for gasified liquid or gaseous fuel centrally disposed in the insert. A burner having a heatable central fuel preparing chamber and a passage system for the air of combustion with a concentric mouth, and a burner tube as an extension of the insert terminates at a spacing from the end wall of the hollow cylinder. In this construction, the fuel can be burnt stoichiometrically free from soot, forms a stable flame free from pulsations and rapidly brings the burner head to high temperatures.
