摘要： A low NOx generating combustor in which a first lean mixture of fuel and air is pre-heated by transferring heat from hot gas discharging from the combustor. The preheated first fuel/air mixture is then catalyzed in a catalytic reactor and then combusted so as to produce a hot gas having a temperature in excess of the ignition temperature of the fuel. Second and third lean mixtures of fuel and air are then sequentially introduced into the hot gas, thereby raising their temperatures above the ignition temperature and causing homogeneous combustion of the second and third fuel air mixtures. This homogeneous combustion is enhanced by the presence of the free radicals created during the catalyzation of the first fuel/air mixture. In addition, the catalytic reactor acts as a pilot that imparts stability to the combustion of the lean second and third fuel/air mixtures.

摘要： In a mixing and flame stabilization appliance in a combustion chamber with premixed combustion, a gaseous and/or liquid fuel is introduced into the combustion air. The combustion air is guided via a plurality of vortex generators (9) arranged adjacent to one another over the width or the periphery of the combustion chamber duct (20) through which flow takes place. Fuel is introduced into the duct (20) in the immediate region of the vortex generators (9). A vortex generator (9) has three surfaces around which flow can take place freely, which surfaces extend in the flow direction, one forming the top surface (10) and the two others forming the side surfaces. The side surfaces enclose between them a V-angle (a) varying in the flow direction and the top surface (10) is disposed at an angle of incidence to the duct wall (21 ) which varies in the flow direction. Thorough mixing of the combustion air and the fuel can be achieved within the shortest distance by means of such vortex generators and the flame can be aerodynamically stabilized at the same time.

摘要： In the operation of gas turbine engines, it is an ever increasing goal to reduce the amount of harmful elements contained within the emissions of the engine. In particular, it is of primary importance to reduce the amounts of nitrogen oxides contained within the emissions. The use of a catalytic combustor is one known means by which the formation of nitrogen oxides may be controlled. However, the use of a catalytic combustor in a gas turbine engine has been known to be effective primarily in the upper ranges of engine operation. The present invention provides a combustor arrangement for a gas turbine engine that employs a first combustor means that utilizes a catalytic bed to react a mixture of fuel and air during an upper range of engine operation and a second combustor means that utilizes a plurality of premixed fuel injectors to ignite a mixture of fuel and air during a lower range of engine operation.

摘要： The gasification-combined power plant of the present invention has a structure wherein a fuel gas is generated by partially oxidizing a carbon-containing fuel 2 with an oxygen-containing gas 3 in the gasification apparatus 1, the sensible heat of the fuel gas is recovered by the heat exchanger 4, char and dust are removed from the fuel gas by the dust collector 5, trace gas components, such as H.sub.2 S and NH.sub.3, are simultaneously removed from the waste gas by the gas separation apparatus 6 based on dry physical adsorption of these components (for example, by a pressure swing adsorption method), the thus separated and removed gas containing high concentrations of trace gas components, such as H.sub.2 S and NH.sub.3, is denitrated and desulfurized by the gas disposal apparatus 7 and then is discharged from the chimney 13 into the atmosphere. With the simultaneous removal of the trace gas components at a high temperature from the fuel gas produced by the gasification apparatus, this plant simultaneously achieves both a high heat efficiency for the gasification-combined power plant as a whole and the reduction of sulfur oxides and nitrogen oxides in the combustion waste gas from the gas turbine.

摘要： A fuel/oxidizer pre-mixing combustion chamber for a turbojet engine is disclosed in which the pre-mixing device is incorporated into the upstream end wall structure of the combustion chamber. The upstream end portion of the combustion chamber, which is in communication with the oxidizer, has a plurality of generally radially extending, "V"-shaped members oriented such that the vertex of the "V" shape faces in an upstream direction. These members extend generally radially between the inner and outer walls which define the boundaries of the combustion chamber. The members define upstream edges and downstream edges which are axially the upstream edges. Fuel injectors extend radially inwardly between these members and are axially positioned between the locations of the upstream and downstream edges so as to spray fuel onto the adjacent sides of each of the members. The downstream edges of the members are circumferentially spaced apart so as to define a passage which is in communication with the oxidizer source and the combustion chamber.

摘要： A combustor includes inner and outer arrays of generally Vee-shaped, radially extending, circumferentially spaced gutters canted in a circumferential direction relative to one another to produce isolated concentric counter-rotating circumferentially directed flows downstream of the gutters. A lean premixed combustion mode is used at baseload operations. At non-baseload operations, particularly low-load operating conditions, a diffusion combustion mode is employed by direct fuel injection into air supplied to one of the isolated flow fields, preferably the radially inner flow field, to produce a stabilized, locally hotter flame, resulting in higher combustion efficiency and lower emissions than otherwise using a lean premixed combustion mode at the non-baseload operating conditions.
