Abstract
A method for burning gas in a burner, including leading the gas through an inner fuel tube and introduction of combustion air through an annular space surrounding the inner fuel tube. This space forms of an outer tube terminated by a conically converging section, wherein the end of the inner fuel tube forms a burner head. The major part of the primary gas is introduced into the upstream end of the burner head, to go into the combustion air that flows past the burner head, whereas a smaller part of a secondary gas is introduced into the free end of the burner head and into the constricted part of the annular channel that surrounds the burner head. The gas flow is accelerated past the burner head due to the reducing cross section and is burned downstream in relation to the burning head.
