摘要： A plurality of catalyst assemblies each have a plurality of sheet catalysts which are arranged in parallel to each other with distances thereby to define a plurality of gas passages. The catalyst assemblies are stacked in a catalytic reactor so that the width direction of the sheet catalysts of one of the catalyst assemblies will traverse the width direction of the sheet catalysts of each of the immediately adjacent assemblies, whereby leading edges of the sheet catalysts of each assembly are exposed to a gas to be treated rising upward in the gas passages.

摘要： A low-NOx boiler comprises a burner for burning gaseous fuel, heat transfer pipes heating water by combustion heat of the burner to generate steam and having a passage through which water flows, a steam drum communicating with the heat transfer pipe and accumulating the steam from the heat transfer pipe, and an exhaust gas duct located in the furnace to exhaust combustion gas generated by combustion of gaseous fuel outside of the boiler. The boiler further comprises unburnt gas burner in the exhaust gas duct for burning unburnt content in the combustion gas flowing in the duct. The unburnt gas burner includes a nozzle for injecting premixture flow of fuel and combustion air and flame holding plate located near the downstream side of the outlet of the nozzle to interrupt the premixture flow to form a circulating flow on downstream side of the flame holding plate. As gaseous fuel and air are mixed in advance and a flame is formed, the flame length can be shortened. Furthermore, the flame holding plate enables to reduce NOx generated. Unburnt gas burner provided in the exhaust gas duct makes it possible to notably reduce the concentration of NOx discharged to the outside of the system.

摘要： A gas turbine combustor comprises a combustion chamber, a premixing chamber in which hydrocarbon fuel and air are premixed, a nozzle with swirler for swirling and injecting the premixed fuel and air into the combustion chamber, to effect premixed combustion, and a fuel nozzle projecting into the combustion chamber and adapted to inject fuel at region wherein the premixed combustion is completed, so as to effect low air-ratio diffusion combustion thereby to produce reducing substance. NOx produced by the premixed combustion is reduced by reducing reaction with the reducing substances, so that the NOx concentration in the combustion gas is reduced. The combustor further includes an after-air ports on a peripheral wall defining the combustion chamber to effect combustion of unburnt substances.

摘要： A low NOx burning method and apparatus wherein a low air ratio flame burned with an amount of air less than an amount of air in a theoretical air ratio required for burning fuel perfectly is formed, and combustibles discharged from the low air ratio flame are burned at a trailing stream of the low air ratio flame while supplying air. The low air ratio flame is a premixing flame burned by premixing the fuel and air, and combustion of the premixing flames is maintained in the vicinity of the premixing flame. In this way, the generation of the NOx during the burning can be greatly decreased, and the required apparatus can be small-sized.

摘要： An atomizer including a fuel supply passage for supplying a fuel, an atomizing medium supply passage for supplying an atomizing medium which is to be mixed with the fuel, a mixing chamber in communication with the fuel supply passage and the atomizing medium supply passage, and spray ports for spraying the fluid mixture consisting of the fuel and the atomizing medium from the mixing chamber. The fuel supply passage and the atomizing medium supply passages are communicated with the mixing chamber through a pre-mixing chamber having an annular cross-section defined by a large-diameter cylindrical surface and a small-diameter cylindrical surface. The fuel and the atomizing medium supplied from the fuel supply passage and the atomizing medium supply passage are pre-mixed the pre-mixing chamber. With this arrangement, it is possible to efficiently mix a slurry fuel and an atomizing medium, thus reducing the particle size of the atomized fuel particles and shortening the flame length. Thus, the atomizer of the invention is indispensable for the boilers which are intended for burning coal-water slurry. The invention makes it possible to form flames with reduced NOx generation and a high burning efficiency through combination between atomizer of the construction described above and a burner having a specific construction.
