摘要： A premixing burner on the double-cone principle consists essentially of two hollow conical partial bodies (111, 112) which are interleaved in the flow direction and whose respective center lines (113, 114) are offset relative to one another. The adjacent walls of the two partial bodies form tangential gaps (20) in their longitudinal extent for the combustion air. Gas inlet openings (117) distributed in the longitudinal direction are provided in the walls of the two partial bodies. The air is guided into the tangential gaps (20) via vortex generators (9) of which a plurality are arranged adjacent to one another. The fuel is introduced into the gaps (20) in the immediate region of the vortex generators (9).Using the novel static mixer which the three-dimensional vortex generators represent, longitudinal vortices without recirculation region can be generated in the inlet gap through which flow occurs. It is therefore possible to achieve extraordinarily short mixing distances at the inlet to the burner with a small pressure loss at the same time.

摘要： The object of the invention is to provide a novel cone burner for gaseous and/or liquid fuels which has a reduced NOx and CO emission. According to the invention, this is achieved in that the sectional cone bodies (1, 2) have a common outlet diffuser (27) at their downstream end. They have a transition region (28) to the outlet diffuser (27), in which the size of the air-inlet slots (7, 8) decreases continuously in the direction (3) of flow. The outlet diffuser (27) is designed to be circular and without air-inlet slots (7, 8).

摘要： In a premix burner for the combustion of gaseous and/or liquid fuel, in which the fuel is injected as secondary flow into a gaseous, ducted main flow, the premix duct (20) through which flow occurs being annular and being defined by an inner (21a) and an outer cylinder wall (21b), and the main flow being guided via vortex generators (9, 9a) which generate longitudinal vortices without a recirculation area and of which a plurality are arranged next to one another over the periphery of the annular duct (20) on at least one duct wall (21), and means for injecting fuel being arranged directly downstream of the vortex generators (9, 9a) on the inner and/or outer duct wall (21a, 21b), the vortex generators (9, 9a) generate such vortices which leave behind a residual vortex after the complete mixing of the fuel with the air of the fuel/air mixture flow. In this case, the annular main flow duct (20) of constant height (H) has a length (L) downstream of the vortex generators (9) and the fuel injection which is in the region of 5 to 20 times its height (H). It subsequently widens to form a circular main flow duct.

摘要： In a double-cone burner, at least one row of nozzles (10) for a gaseous fuel containing highly reactive components and having a medium calorific value are arranged on the periphery of the partial conical bodies (1, 2) of the burner near the burner outlet at a distance of approximately 30% of the nominal burner diameter. In addition, there is a fuel conduit (11) and a distributing passage (17), placed in the region of the nozzles (10), for the highly reactive fuel. The gaseous fuel (15) containing highly reactive components is injected at high velocity through the nozzles (10), which have a diameter which is smaller than 1% of the nominal burner diameter, into the zones of high air velocity and the penetration depth and the direction of the fuel jets are matched to one another in such a way that ignition only takes place behind the burner, after mixing has occurred.

摘要： In a burner for premixing-type combustion of a liquid and/or gaseous fuel, which essentially comprises hollow conical part-bodies (1, 2) positioned one upon the other, the center lines of which extend mutually offset in the longitudinal direction, whereupon tangential inlet openings (1b, 2b) are formed on both sides of the burner, a fuel (5a) is admixed to the combustion air (13) flowing into the interior (3) of the burner in that area. This admixture is accomplished via a number of nozzles (9, 10), which act in the region of the inlet openings (1b, 2b). The fuel through these nozzles is injected with a small spray cone angle in the longitudinal direction of the slot. The fuel vaporization takes place essentially only in the inlet openings of the burner, with the result that only a fuel vapor enters the interior (3). A further central nozzle (4) supplied with a liquid and/or gaseous fuel provides assistance in the form of a limit fuel quantity. The ignition of the mixture (4a, 5a, 13) takes place at the outlet of the burner, stabilization of the flame front (14) being brought about in the region of the burner aperture by a return flow zone (15).

摘要： A premixing burner (X) which consists essentially of at least two hollow partial bodies (1, 2), which are positioned one above the other and whose center lines (1b, 2b) extend offset relative to one another in the longitudinal direction of the partial bodies (1, 2), is employed for hot gas generation, for example in a firing plant. Due to this offset, tangential inlet slots (21, 22) respectively occur through which a combustion airflow (15) flows into the internal space (14) of the premixing burner (X). Venturi mixers (32) with fuel nozzles (36), through which a fuel (31) is introduced into the combustion air (15) flowing past at this point, are arranged in the region of these tangential inlet slots (21, 22).

摘要： In a method of operating a plant with staged combustion, the first combustion stage (1a) is operated with a fuel/air mixture (3) whose air coefficient is larger than the overall air coefficient of the combustion system. The hot combustion gases (5) from the first combustion stage (1a) are mixed with an additional fuel/air mixture (4) whose air coefficient is smaller than the overall air coefficient of the combustion system, before the further combustion in the second stage (2a) takes place. Since hot-gas backmixing is no longer required in the second stage (2a) for the flame stabilization, this combined mixture burns without the formation of further NOx emissions.

摘要： In the case of a heat generator which essentially consists of a premix burner (100) and a flame tube (1), the hot gases (10) from the combustion in the premix burner (100) are fed into the flame tube (1), and there undergo staged post-combustion. This post-combustion takes place by means of a first post-combustion stage (11) and a second post-combustion stage (12). The air/fuel mixture (11a, 12a) is provided for each post-combustion stage (11, 12) in individual mixers (200, 300). These mixers are arranged axially with respect to the flame tube (1) and work in such a way that injection of the corresponding mixture (11a, 12a) makes it possible to obtain different combustion zones which extend in a staged sequence over the flame tube (1). By virtue of this staged post-combustion mode NO.sub.x emissions can be reduced by a factor of 5 compared to conventional techniques.

摘要： In a burner for operating a combustion chamber, which burner essentially comprises a swirl generator (100), a transition piece (200) arranged downstream of the swirl generator, and a mixing tube (20), transition piece (200) and mixing tube (20) forming the mixing section of the burner and being arranged upstream of a combustion space (30). The swirl generator (100) itself comprises at least two hollow, conical sectional bodies (140, 141, 142, 143) which are nested one inside the other in the direction of flow, the respective center axes of these sectional bodies running mutually offset in such a way that the adjacent walls of the sectional bodies form inlet ducts (120), tangential in their longitudinal extent, for a combustion-air flow (115). In the region where the combustion-air flow (115) flows into the swirl generator (100), fuel injectors (116, 116a) are arranged on both sides along the inflow edges, which fuel injectors act offset with respect to one another, in such a way that the inflow cross section of the duct (120) is integrally covered with fuel, with the result that a maximized premixing is achieved.
