Description

The burner described in German Patent Application No. 1917959 and in English Patent Specification No. 1 299229 is a combined burner for premixing the entire amount of gas. In front of the piezo air tube, which includes the oil nebulizer, there is a pulley deflector pulley which gives a portion of the gas-primary air momentum. Secondary air collides with a fur.ttos baffle to pre-mix the gas. As the elements are stationary, the length and shape of the flame cannot be changed. The RAY variomat type burners manufactured by FILAY ÖL-UND GASBRENNER GMBH employ a rigidly mounted torque conveyor element, which has a series of concentricly arranged baffle blades and a rotating impeller in the circumference of the impeller. This impeller gives you a certain amount of torque that can't be changed just by installing another impeller.

German Patent Laid-Open Patent Application Serial No. 2431645 discloses an oil burner jigsaw consisting of two pivoting pulleys. One of the discs has slits slightly broadening radially from the central circular contour to the outer part, the other disk has the same number and, for each of the slots, a flap. Rotation of the discs relative to each other Refer to the cross-section of the inlet openings so that the proportion of air fluctuated can be varied.

For some types of burners, flushing elements having a constant throughput cross-section are used to control the power of the burner by being mounted in a narrowly axially displaceable manner in a confined diffuser or similar design. The trigger also functions as a choke. The conveyor gives you a pre-determined hand bet that cannot be changed.

In one embodiment, the impeller is secured to the fuel inlet and moves along with the longitudinal axis of the burner. Such a solution is described in French Patent No. 234 2010, oil burner and Rielló's prospectus for gas burner (eg Gas Type 3).

At block burners (eg TO 7-8) of the Institute of Petroleum Research, the throttle is limited by ·, movable at a distance determined by the minimum torque requirement (internal position) and the cone angle (external position) of the oil discharged from the atomizer. A common disadvantage of known burners is that without replacement of parts, only one burner can change a parameter '(flame length or torque). By changing the position of the throttle, the flame loss generally varies as a function of power. Changing the throughput cross section of the heat station burner to the damper element changes the amount of air flowing without changing the angle of rotation, so it is also used for power control.

Because the parameters of the fireplaces determine the parameters of the burner, so many types of burners are actually used.

It is an object of the present invention to provide a combustion apparatus (burner) which can be used for any apparatus having the same heat load, but with different combustion parameters, by adjusting the flame parameters (flame length and flame radius) corresponding to the combustion parameters.

BACKGROUND OF THE INVENTION The present invention relates to a gas, oil or combined burner of variable flame length and angularity, having a fuel, combustion air supply, gas distribution drum and gas lance system and / or an oil atomizer, characterized by an actuator for moving axially moving an inner torsion element with through openings, flaps, flanges, an outer torsion element connected to the flange or tabs of the inner flutter element, preferably offset axially, by means of holes and / or / preferably circular slits , is pivotally arranged to fit the inner bounce-drive element,

- an adjustable bogie adjuster with flow apertures, baffles, holes and / or slots, preferably in a circular shape, var.

The outer tuft element may be provided with circular openings of a size suitable for receiving gas lances, as well as through-pass gaps formed at an angle of 20 to 40 °.

The combustion air blower fan impeller 2 is located in the burner housing 1, which conveys the required pressure and amount of combustion air through the damper system 3 to the burner head arranged in the burner housing 4. The damper system 3 is actuated in accordance with the required burner power in combination with gas and oil volume control valves not shown in the figure. At the end of the actuator 9 mounted on the inside of the gas distributor drum 7 arranged around the oil spreader 6 located in the axis of the burner, the inner bung spreader element 12 is provided, which is provided with through holes 10 and spreader blades 11. It is expedient to make the blades 11 by cutting out the annular material and bending it by pressing. Connected to the flange or tabs 13 on the circumference of the inner tumbler twisting member 12 is a suitably offset mounted outer tumbling member 19, which, with its bores 14 and / or circular slots 15, and a predominantly circular fit for receiving gas lances 16 It also has apertures 17, which in one embodiment have reciprocating slots 18 formed between the gas lance 16 and the circular apertures 17 at an angle of 20 to 40 °. In the absence of gaps 18, the outer gate member 19 does not perform gapping. Attached to the inner tumbler actuator 12 is the pivotable tumbler actuator 24, which is adjusted by turning the actuator 8. The adjusting baffle member 24 is provided with through holes 20 and baffles 21, bores 22 and / or slots 23 preferably in a circular shape. From the gas distributor drum 7, the gas is ca. 30% of the front end is provided with a 25-hole bore wreath into the premix space 26 where the ignition electrodes 27 are located. The greater part of the gas enters the burner 5 through the holes 28 of the gas lance 16. The amount of gas required for ignition is supplied to the burner 5 via the spark line 29. In the gas burner embodiment, the oil atomiser 6 and the oil supply system are not installed. In the case of an oil burner, the gas distributor drum 7 and the gas lance 16 are not installed and the openings 17 are also missing. The amount of gas flowing out through the borehole 25 is mixed in the premix space 26 with a portion of the combustion air flowing in the burner head 5 and ignites through the baffle 12 and the baffle 24 towards the burner 9. Depending on the relative position of the two hopper conveying elements, the flow direction of the gas-air mixture is different. When the through openings 10 and 20 overlap, the mixture receives maximum angular momentum (Fig. 5), since all and 21 impeller blades are in the entire flow path of the mixture.

When the orifice 10 is covered by the portion 22 and / or slots 23 (Fig. 4), the mixture passes almost smoothly. Between the two extreme values, the angular momentum can be varied by rotating the adjusting tumbler adjusting element 24.

The greater proportion of gas flowing out through the holes 28 in the gas lance 16 flows in front of or behind the outrigger system 5, depending on the position of the outer tumbler element 19. Almost all of the gas is premixed when the buckling system is fully extended. Only the outflow at the front holes of the gas lance 16 is approx. A proportion of 10% of the gas enters the burner 5 without premixing. By axially adjusting the pulley roller system, the proportion of the premix may be varied, rotating the pitcher roller 24 will adjust the size of the swing and thus the flame pattern to the humidity of the furnace (boiler, furnace, etc.) to which we use a burner.

The burner of the present invention can advantageously be used to form a single burner family (especially block burner) which replaces the currently used 20 burners of very many types and sizes. A further advantage is that it consists of elements that are well suited for serial production.
