Abstract
Die Erfindung betrifft einen Gasbrenner (1) für ein Heizgerät (2) mit einem Gebläse zur Förderung eines Gas-/Luft-Gemisches sowie einer Wirbelerzeugungseinrichtung (7) in einem in eine Verbrennungszone (5) einmündenden zylindrischen Strömungsweg (4) des Gas-/Luft-Gemisches, welcher in einem abgeschlossenen Brennraum (6) angeordnet und einem Wärmetauscher (3) zugeordnet ist.The invention relates to a gas burner (1) for a heater (2) with a blower for conveying a gas / air mixture and a vortex generating device (7) in a cylindrical flow path (4) of the gas / air inlet opening into a combustion zone (5). Air mixture, which is arranged in a closed combustion chamber (6) and associated with a heat exchanger (3).
Der Erfindung liegt die Aufgabe zugrunde, einen emissionsarmen Gasbrenner für ein Heizgerät mit kompakter Bauform zu schaffen.The invention has for its object to provide a low-emission gas burner for a heater with a compact design.
Erfindungsgemäß weist der zylindrische Strömungsweg (4) an seiner Ausmündung eine sich aufweitende Auslassgeometrie (8) auf, welche eine Barriere zwischen der Flamme, zumindest der Flammenwurzel, und den im Brennraum rezirkulierenden Heizgasen bildet. According to the invention, the cylindrical flow path (4) has at its outlet a widening outlet geometry (8), which forms a barrier between the flame, at least the flame root, and the hot gases recirculating in the combustion chamber.
