Verfahren zur Regulierung der Flammengüte eines atmosphärischen Gasbrenners und Gasbrenner zur Durchführung des Verfahrens

摘要

The invention relates to a method for controlling the flame quality of an atmospheric gas burner, in which the combustion gas is introduced via a gas nozzle (8) into a mixing chamber (3) into which in addition to the combustion gas a minimum volumetric flow of primary air is introduced via a feed cross-section (2), and the mixture of combustion gas and primary air formed is led into the combustion chamber via a combustion surface (6) provided with a flame opening (7). The volumetric flow of the primary air is varied between a predetermined minimum volumetric flow and a maximum volumetric flow as a function of the combustion chamber temperature prevailing in the region of the combustion surface. As a result, automatic adaptation to changing gas properties is possible.
