Description
- The invention concerns a gas burner with the combustion head with axial main performance nozzles, which is arranged in the axis of a cylindrical casing which is open from below for the flow of the combustion air, wherein there are other fuel nozzles arranged on the output of the casing, wherein in front of the primary head, the fuel tube is divided into a plurality of tubes arranged in a circle, whose nozzles are orientated into the gas burner discharge.
- Gas burners are designed to combustion of gaseous fuels and serve primarily as a source of heat for overpressure and underpressure hot water boilers. However, they can be used for other appliances with adequate space for combustion which will not be stressed by external heat. Structurally these gas burners are designed as monobloc, i.e. the swirler and all components are part of the gas burner body. The gas burner operation is fully automatic, also suitable for unattended control of boiler rooms. In terms of a mixing method of natural gas with air, block burners belong to burners without premixing of gas with air. The mixing takes place until the gas burner output while simultaneous combustion of the created mixture. According to the combustion method, block burners belong to burners with free flame. For this reason are gas burners provided with a combustion head, which combusts the fuel in one step. During one-step combustion occur temperature peaks, which cause creating of thermal NOx. This combustion process does not enable to reduce NOx emissions sufficiently. The aim of this invention is to reduce emissions of thermal NOx.
- From a structural viewpoint, there are many burners whose combustion head is arranged in the axis of cylindrical casing which is open from below where flows the combustion air, mixed with the fuel outcoming from the outside nozzles on the head and then there are other gas nozzles arranged on the discharge of the casing. Such an arrangement is known e.g. from the document
EP 1335163 A1 . It is also common that in front of the primary head, the fuel tube is divided into a plurality of tubes arranged in a circle whose nozzles lead to the gas burner output. Such an arrangement is known e.g. from the documentUS 4,505,666 . - The aim of invention is to present a gas burner, which would allow to reduce emissions of thermal NOx.
- The abbove mentioned disagvantages are eleminated by thw gas burner according to the invention, which principles consists especially in that on the tube portion leading from the gas distributor to the central primary head a reduction piece is arranged, provided with a passing-through opening which is smaller than the opening in the tube portion, and on the reduction piece the primary head is arranged provided with the swirler and in front of the swirler in the direction of the gas burner output, radial stabilization nozzles around the circumference of the head are provided.
- The invention will be described by use of drawings in which
Fig.1 shows a front view of the gas burner according to the invention,Fig. 2 is a sectional view of the gas burner opening according to line A-A ofFig. 1 in the scale 1:2 andFig. 3 is a sectional view of a gas burner according to line B-B ofFig.2 . - From
Fig.2 it can be seen that the gas burner consists of a gaseous part which consists of the gas supply 7 tube, anelbow 8 and anincome tube portion 9. There is also a not shown air box in front of the gaseous part. Theincome tube portion 9 leads into a gas distributor 16 from which extends a tube portion 11 on which a reduction piece 12 is arranged. There is a thread at the end of the reduction piece 12, through which aprimary head 15 is installed. Theprimary head 15 is provided with a radially arrangedswirler 13 on its lateral surface. The reduction piece 12 is provided with a passing-through opening 17 which reduces passing of gas. On the front of theprimary head 15 there are provided axial main performance nozzles 19 andstabilization nozzles 20 on its cylindrical casing, namely in front of theswirler 13, viewed from a gas burner output. Secondary gas is supplied from a gas distributor 16 intosecondary heads 6 via distribution tubes 10. At the ends of outer walls 21 of distribution tubes 10 there is perpendicularly arranged thecylindrical casing 3, creating the primary combustion channel. The gas is distributed from aring 22 consisting of arear wall 4, alongitudinal wall 2 and afront wall 23 by sixtubes 5 to sixsecondary heads 6 withnozzles 18. Where is notube 5, there is thefront wall 23 which closes thering 22. There is acollar 14 above thefront wall 23. - In
Fig. 1 and 3 the construction of the gas burner parts is illustrated from other view. - Gas-air mixture of the first (primary) stage is formed by the
swirler 13 of the centralprimary head 15. The system ofnozzles 19,20 of theprimary head 15 is formed in such a way that a part of these nozzles, namely the axial nozzles 19 are main performance nozzles and theother nozzles 20 are stabilization nozzles, which secure combustion stability. -
Radial nozzles 20 create turbulent swirling of the gas/air mixture. Their placement in the vicinity ofswirler 13 is important because of streaming of the combustion air, which has in this area lower velocity. In this way a very stable area of flame is created, which lights up and stabilize the performance nozzles 19. - In the primary section within the
cylindrical casing 3 the pressure is reduced, in a comparison with the secondary section in the tube portion 11 by use of the reduction piece 12. The discharge of gas is in the area ofcylindrical casing 3 lower, which is a prerequisite for good combustion stability. The secondary section has sixsecondary heads 6 placed around the outer circumference of thecasing 3 forming the flame tube. The secondary gas flows radially from the nozzels insecondary heads 6 and enters the gas-air mixture. - The first stage is the combustion in the flame tube with huge surplus of combustion air. The first stage has an output of about 20%. In the second stage remaining gas needed for a specific power output in a mode with surplus of air, ideally in the range of 1.05 to 1.2 times of the stoichiometric ratio is combusted.
- The
swirler 13 creates turbulent air flow before mixing of the oxidizer with fuel. Turbulent air flow ensures a perfect mixing with fuel. The secondary section has six secondary heads placed around the outer circumference of the inner flame tube. The secondary gas flows radially from the nozzles and does not create a rotary motion. Gas distribution is realized by thedistribution ring 22 into which gas flows throgh twoincome tube 8. NOx emissions in this arrangement are at the level of about 25 ppm / Nm3 combustion products.
