摘要： An object of this invention is to accelerate further mixing of a fuel and air independently of a flow rate of the fuel.A gas turbine combustor comprises: a fuel nozzle for blowing out a gas fuel; an air nozzle plate with an air nozzle for jetting out the fuel and air into a combustion chamber after the blowout of the fuel from the fuel nozzle; and an obstacle formed inside the air nozzle; wherein the obstacle causes a collision of the fuel jet blown out from the fuel nozzle, and hence causes turbulence in an airflow streaming into the air nozzle.According to the invention, mixing between the fuel and the air can be further accelerated independently of the flow rate of the fuel.

摘要： An object of the present invention is to provide a gas turbine combustor that supports hydrogen-containing gas having a high burning velocity and is capable of performing low NOx combustion without reducing reliability of a burner. A first fuel nozzle is provided upstream of a combustion chamber and supplies fuel for activation and hydrogen-containing gas. The combustor has a primary combustion zone, a reduction zone and a secondary combustion zone. In the primary combustion zone, the fuel supplied from the first fuel nozzle is combusted under a fuel rich condition to form a burned gas containing a low concentration of oxygen. In the reduction zone, a hydrogen-containing gas is injected into the combustion chamber through a second fuel injection hole from a second fuel nozzle so that NOx generated in the primary combustion zone is reduced by an oxygen reaction of the hydrogen. In the secondary combustion zone, air for lean combustion is supplied into the combustion chamber so that unburned part of fuel is combusted under a fuel lean condition.
摘要翻译：本发明的目的是提供一种燃气轮机燃烧器，其支撑具有高燃烧速度的含氢气体并且能够进行低NOx燃烧而不降低燃烧器的可靠性。第一燃料喷嘴设置在燃烧室的上游，并供应用于活化的燃料和含氢气体。燃烧器具有主燃烧区，还原区和二次燃烧区。在主燃烧区域中，从第一燃料喷嘴供给的燃料在富燃状态下燃烧，形成含有低浓度氧气的燃烧气体。在还原区中，通过来自第二燃料喷嘴的第二燃料喷射孔将含氢气体注入燃烧室，使得在一次燃烧区中产生的NOx通过氢的氧反应而被还原。在二次燃烧区域，用于稀薄燃烧的空气被供应到燃烧室中，使得燃料的未燃烧部分在燃料稀薄状态下燃烧。

摘要： A gas turbine combustor includes plural multi-coaxial-injection-hole burners in which plural fuel nozzles and plural air holes provided in an air plate to correspond to the respective fuel nozzles are coaxially arranged. Each of the multi-coaxial-injection-hole burners includes a first coaxial injection burner disposed on an inner circumferential side, and a second coaxial injection burner disposed on an outer circumferential side, and a diameter of the air holes of the first coaxial injection burner is smaller than a diameter of the air holes of the second coaxial injection burner. Combustion for carrying out flame holding of a gas turbine combustor is performed by the first coaxial injection burner, and low NOx combustion of the gas turbine combustor is performed by the second coaxial injection burner.
