Definitions
- Burners for gaseous fuels in particular for heating boilers, and methods for burning gaseous fuels
- the present invention relates to a burner for gaseous fuels, in particular for heating boilers, and a method for burning gaseous fuels with excess air when the load changes in a combustion chamber.
- the present invention aims to create a burner for gaseous fuels, which a possibility of regulation on a larger scale with optimal operation of the
- the burner according to the invention which meets these requirements in a broad sense, is characterized in that displacement and/or rotary means are provided in order to achieve an at least approximately constant volume ratio of gas and combustion air at least in the power range of 10-100% of the nominal power ensure.
- FIG. 1 shows a longitudinal section through a burner for gaseous fuels mounted on a heating boiler.
- a gas burner 1 is installed in a boiler 2, the power of which is, for example, up to 300 KW.
- a boiler wall 3 with a part of the water space 4 can be seen in fragments from the boiler 2 .
- the gas burner 1 is screwed to the boiler wall 3 by means of a fastening flange 6 .
- a lateral blower air supply socket 7 brings combustion air from the blower (not shown) into an air antechamber 9, which is preferably cylindrical. It is delimited by an enveloping tube 10 and an outer base 11 welded to it. Inside there is a cylinder-shaped air control plate 12 with lateral openings 13.
- the burner housing also includes an immersion tube 14, in which there is also a tubular slider 15 is arranged to be longitudinally displaceable. Immersion tube 14 and slide. 15 are slidably mounted one inside the other by two guide rings 16, while a corresponding sealing ring 17 prevents the gas/air mixture escaping from the slider 15 from rising.
- a burner pipe 19 is welded to the extension of the tubular slide 15, the end of which is closed by a base 20, while lateral flame holes 21 allow the combustible gas/air mixture to escape.
- the slide 15 which is open at the rear and is bounded on the outside by the outer floor 11 on the one hand and the air control plate 12 on the other, there is an inflow chamber 23, in which the combustion air flowing in through the openings 13 meets the correspondingly exposed openings 31 incoming gas to to flow together into a mixing chamber 24 .
- Perforated plates such as air control plate 12, are well known in fluid dynamics. Here they serve to improve the mixing process in order to premix the gas and the air before the mixing space 24 .
- a static mixer 26 is arranged in the mixing chamber 24 .
- turbulators such as those used in flue gas pipes, or similar baffles, which produce optimal mixing to form a homogeneous gas/air mixture, can be used.
- the gaseous fuel passes through a gas supply pipe 28 and a connecting piece 29 into a gas metering pipe 30 which is provided with corresponding lateral openings 31 .
- the gas dosing tube 30 is penetrated by a regulating rod 33 which can be moved back and forth from the outside and which is guided by means of a stuffing box guide 34 and by means of an end holder 35 and a screw connection 36 with a gas control tube 37 and the slide 15 is firmly connected. Ignite gas escaping from the flame bores 21 is shown as gas flames 39 .
- the fuel gas supply on the one hand and the combustion air supply on the other hand as well as the active burner surface can be controlled by one and the same element, consisting of the slide 15, the burner tube 19 and the gas control tube 37, this control is optimal.
- This element 15, 19, 37 can also be moved by means of a single reciprocating movement of the regulating rod 33.
- Delivers supply pressure and the lines are dimensioned so that Lm inside the Gasdosierrohr 30 there is a substantially constant pressure, so that through the exposed, opening into the inflow chamber 23 openings 31 one of the
- the fan conveying the combustion air is normally a fan with non-proportional or constant delivery characteristics, i.e. a fan with a non-constant delivery rate.
- the fan conveying the combustion air is normally a fan with non-proportional or constant delivery characteristics, i.e. a fan with a non-constant delivery rate.
- This circumstance is fan-specific in the arrangement of the openings 31 in the gas metering tube 30 to be taken into account accordingly, so that theoretically gradual, because it is about concrete openings and notteur ⁇ continuous slots, practically but steplessly into the inflow chamber 23 air and gas flow in, with an at least approximately constant quantity ratio of gas and combustion air being ensured essentially independently of the position of the regulating rod 33 or the slide 15 in the range of 10-100% nominal output.
- This inhomogeneous mixture then flows out of the inflow chamber 23 through the static mixer 26, which it leaves as a completely homogeneous gas-air mixture in order to subsequently flow out through the openings 31 released according to the position of the slider 15 and to form gas flames 39.
- the openings 13 and 31 are arranged and selected in shape (round, square, etc.) in such a way that the condition of the constant quantity ratio of gas/combination air is maintained over a wide performance range.
- a rotary movement of the control pistons can also be provided, or a mixed movement.
- the regulating rod 33 can be regulated by means of selected control variables, for example the flue gas outflow temperature and the like, in order to create a planned program by moving it accordingly.
- the gas burner described is extremely simple in construction, reliable in operation and easy to adapt to external conditions such as a fan and the like.
Abstract
Un brûleur de combustibles gazeux, en particulier pour chaudières de chauffage, comprend des organes coulissants et/ou rotatifs (15, 37) qui assurent un rapport au moins approximativement constant entre les quantités de gaz et d'air de combustion, au moins dans une plage de puissance comprise entre 50% et 100% de la puissance nominale. Un élément de commande, un piston (15, 37) par exemple, sert à modifier simultanément l'injection de gaz et d'air dans une chambre de mélange (24). Un premier piston (15) mobile de commande, rotatif et/ou coulissant, commande avec la surface extérieure de son corps la quantité d'air de combustion. Un deuxième piston de commande (37) est agencé à l'intérieur du premier piston tubulaire de commande (15), de préférence coaxialement au premier. Ce deuxième piston (37) commande la quantité de gaz avec la surface intérieure de son corps. Les deux pistons de commande (15, 37) sont fermement reliés l'un à l'autre, et peuvent être mis en rotation ou en mouvement alternatif par un organe d'actionnement (33).A gaseous fuel burner, in particular for heating boilers, comprises sliding and / or rotating members (15, 37) which ensure an at least approximately constant ratio between the quantities of gas and combustion air, at least in one. power range between 50% and 100% of nominal power. A control element, for example a piston (15, 37), serves to simultaneously modify the injection of gas and air into a mixing chamber (24). A first movable control piston (15), rotating and / or sliding, controls with the outer surface of its body the quantity of combustion air. A second control piston (37) is arranged inside the first tubular control piston (15), preferably coaxially with the first. This second piston (37) controls the amount of gas with the interior surface of its body. The two control pistons (15, 37) are firmly connected to each other, and can be rotated or reciprocated by an actuator (33).
