Abstract
Die Erfindung betrifft ein Gasbrenner mit einem Brennerkörper (15), der zumindest teilweise von einer porösen Struktur durchdrungen ist, wobei in der porösen Struktur die Verbrennung eines Brenngas-Luft-Gemisches stattfindet, und wobei dem Brennerkörper zum Abtausch der entstandenen Verbrennungswämre wenigstens ein Wärmetauscher (17) zugeordnet ist. Zur Reduzierung von Kohlenmonoxidemissionen ist es erfindungsgemäß vorgesehen, daß die verfügbare Brennzone des Brennerkörpers in wenigstens zwei Teil-Brennzonen (A,B) untergliedert ist, und daß aus der ersten Teil-Brennzone (A), die im Bereich einer bei kleinen Brennerleistungen gebildeten Reaktionszone angeordnet ist, weniger Wärme in den den Brennerkörper umgebenden Raum ausgekoppelt ist, als aus den übrigen Teil-Brennzonen. The invention relates to a gas burner with a burner body (15) which is at least partially penetrated by a porous structure, the combustion of a fuel gas / air mixture taking place in the porous structure, and wherein the burner body has at least one heat exchanger for exchanging the resulting combustion heat. 17) is assigned. To reduce carbon monoxide emissions, it is provided according to the invention that the available combustion zone of the burner body is subdivided into at least two partial combustion zones (A, B), and that from the first partial combustion zone (A), the reaction zone formed at low burner outputs is arranged, less heat is coupled out into the space surrounding the burner body than from the other partial combustion zones.
