摘要： A method is provided for CO2 separation from a combined-cycle power plant with exhaust-gas recirculation and CO2 separation. The hot-gas flow is split into a recirculation flow and an exhaust-gas flow before the final turbine stage in the turbine. A first partial flow remains in the turbine and carries out expansion work in the conventional form, before its waste heat is dissipated, for example in a waste-heat boiler, and the gases are recirculated into the inlet flow of the gas turbine. A second partial flow is diverted before the final turbine stage, and emits its waste heat in an HRSG/heat exchanger, before CO2 is separated from the exhaust-gas flow at an increased pressure level.

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.

摘要： In a premix burner, the swirl-stabilized interior space (18) has a conical inner body (13) running in the direction of flow. The outer casing of the interior space (18) is pierced by tangentially arranged air-inlet ducts (11a, 12a) through which a combustion-air flow (16) flows into the interior space (18). The swirl flow (23) forming in the interior space (18) is enriched with a fuel via at least one fuel lance (17). The mixture of the two media is then formed in the downstream mixing tube (21). The mixing tube (21) then merges into a combustion space (31) via a jump in cross section, a backflow zone (32) forming in the region of the plane of the jump in cross section, which backflow zone (32) ensures the stability of the combustion.

摘要： In a burner for operating a combustion chamber, which burner essentially comprises a swirl generator (100) and a mixing section (220) arranged downstream of the swirl generator, this mixing section acting upstream of a combustion chamber (30), the swirl flow induced by the swirl generator (100) is directed via transition passages (201) into the mixing section (220). At the outlet of a mixing tube (20) belonging to the mixing section (220), the burner front (70) of the mixing tube (20) is provided with at least one torus-like notch (71) on the combustion-chamber side. Thus the stability of the backflow zone (50) can be intensified, which has a positive effect on the combustion from all aspects.

摘要： In a burner of the double-cone design for burning liquid (12) and gaseous fuels (16), the at least two sectional cone bodies (1, 2) overlap at least partly, the overlap angle (.delta.) increasing in the direction of flow of the burner, and the distance between the fuel injectors (15) and the air-inlet plane (21) into the burner increasing simultaneously with the increase in the overlap angle (.delta.). As a result, the air-inlet plane (21) and the fuel-injection plane (22) no longer coincide. Improved premixing of the gaseous fuel (16) with the combustion air is achieved by the invention, which leads to lower NOx emissions of the burner and to lower thermal loading of the burner front.

In the region of the tangential combustion-air-directing inflow ducts (101b-104b), fuel-directing ducts (121-124), the cross section of flow of which is designed for a low-calorific fuel (116), extend along the swirl generator (100). The fuel-directing ducts (121-124) end at a distance upstream of the transition of the tangential inflow ducts (101b-104b) into an interior space of the swirl generator (100), whereby partial mixing between the two media (115, 117) takes place before the mixture flows into the interior space (118). In addition, this setting-back provides sufficient space for other fuel-directing lines (111-114) in this region.

摘要： In a combustion chamber of a gas-turbine group which essentially comprises a mixing section (2) for premixing an air/fuel mixture (16) and a downstream combustion space (3), a jump (5) in cross section is provided at the transition between the two said flow sections (2/3). This jump (5) in cross section induces the cross section of flow of the combustion space (3) and at the same time forms outer recirculation zones (10) in the combustion space (3). Flow passages (4) branch off in the end phase of the mixing section (2), which flow passages (4) then lead into the outer recirculation zones (10). A portion (9) of the air/fuel mixture flows out of the mixing section (2) through these flow passages (4) and into the outer recirculation zones (10), the portion being enriched here with an additional fuel (6). This fuel (6) is introduced via a circular line (19) provided with bores (18). The branched off mixture (9) constitutes a self-igniting pilot flame in the outer recirculation zones (10), which pilot flame substantially stabilizes the flame front (20).

摘要： In a boiler plant for heat generation, which consists essentially of a combustion space and of a burner acting on the head side of the combustion space, this combustion space is divided into two parts (17,102a) by the insertion of an annular disk (103). A limited internal backflow zone (24) forms in the front part (17) in interaction with this disk (103). This disk (103) then causes external backflow zones (106) fed by recirculated flue gases (30) to form within the front part (17) of the combustion space, the flue gases of said external backflow zones being introduced into the combustion process of the burner, said backflow zones (24, 106) being in each case separated locally from one another. Better flame stabilization, lower pulsations and markedly lower pollutant emissions can thereby be achieved when the burner is operating.
