Abstract (en)

1. A burner system for a gaseous fuel having a gas supply line and an air supply line (16; 8), both of which terminate in the region of a gas and air mixing chamber (13) enclosed by a wall (18), and in said burner system the gas supply and the air supply to the mixing chamber (13) being able to be simultaneously varied in a fixed ratio of gas to air via variable cross-section ducts or ports (28; 20) by means of a mechanism which can be adjusted along the longitudinal axis in accordance with the required burner output, viz. - the gas supply by means of a displaceable conical closure member (21; 121) which protrudes through an adjustment port (20) in the gas supply line (16), and - the air supply by means of a further displaceable member (25) cooperating with the conical closure member (21), characterized in that a) the adjustment port (20) is provided in a diaphragm wall (17) fitted in the gas supply line (16), b) the conical closure member (21; 121) is rigidly joined to a cylindrical box-type component (25) which encloses said closure member and constitutes a further member, its bottom side being open and receiving the stream of gas from the gas supply line (16) and its other side incorporating a gas discharge port (27), c) the wall (18) enclosing the gas and air mixing chamber (13) is cylindrical or quasi-cylindrical and in said wall are set the ducts (28) for the air supply, and d) the box-type component (25) slides inside the wall (18).

Abstract (de)

Brennerainrichtung für einen gasförmigen Brennstoff, mit einer Brennstoff- und einer Luftzufuhrleitung (16, 38; 8), die beide im Bereich einer von einer Wandung umschlossenen Brennstoff-Luft-Mischzone (14) enden. Bei der Brennereinrichtung sind die Luft- und die Brennstoffzufuhr in die Mischzone gleichzeitig über querschnittsveränderbare Kanäle (28; 20) mittels einer entlang der Längsachse verstellbaren schieberartigen Vorrichtung (22) entsprechend der erforderlichen Brennerleistung in einem festliegenden Brennstoff-Luft-Verhältnis veränderbar. Die Gaszufuhr ist mittels eines Schließkegels (21) verstellbar, der durch eine Verstellöffnung (20) einer in die Gaszufuhrleitung eingebauten Blendenwand (17) ragt. Mittels eines mit dem Schließkegel (21) verbundenen Dosenteils (25) sind gleichzeitig die Luftzuführkanäle (28) der Wandung (18) der Mischzone (14) querschnittsveränderbar.
