摘要： PURPOSE:To reduce the size of a combustion device by supplying tertiary air forcibly to a reacting surface in the secondary combustion chamber to shorten the length of flame. CONSTITUTION:A premixture of fuel gas and primary air is sent to a mixture chamber 3 in a burner 2 and injected into a primary combustion chamber 9 through a flame hole surface 5. A secondary air flows into the primary combustion chamber 9, embracing the flame 15 uniformly from both sides of the flame hole surface 5. A tertiary air flows into a tertiary air chamber 16 and is injected through an air jet nozzle 17 toward the flame 15 formed in the secondary combustion chamber 13, and unreacted component reacts with the supplied tertiary air. With sufficient oxidizing agent supplied to the combustion reactor surface, combustion reaction in the secondary combustion chamber 13 progresses rapidly keeping the flame 15 extremely short making it possible to reduce the size of a combustion device.

摘要： PURPOSE: To impart a fast-heating characteristic at a firing and to improve a rising at the start of a heating operation in the combustor with a carburetor by a structure wherein a heavy heat pipe is arranged between a combustion chamber and the carburetor.
CONSTITUTION: Between the combustion chamber 4 and the carburetor 7, a gravity type heat pipe 10 for heating a vaporization chamber 8 of the carburetor 7 is arranged. The heat pipe 10 is embedded at the horizontal part at the lower end into the lower part of a burner 5 in the combustion chamber 4 and at the rising part at the upper end into the carburetor 7. At the firing of the burner 5, a heater 9 of the carburetor 7 is supplied with electric power to heat the carburetor 7. In this instance, the carburetor 7 is separated from the side wall 1 of the combustion chamber 4 and a pipe 10 has only a small thickness and hence a small heat capacity. Further, the pipe 10 does not transmit the heat from the upper end to the lower end. Therefore, the heat generated by the heater 9 is not transmitted to the combustion chamber 4, whereas the vaporization chamber 8 reaches immediately a desired temperature. This produces the instant vaporization of a mixture of fuel and air upon being introduced into the vaporization chamber 8, and the vaporized mixture is then fed to the burner 5.

摘要翻译：目的：为了赋予燃烧时的快速加热特性，并且通过具有燃料室和化油器之间的重型热管的结构，通过化油器在燃烧器的加热运转开始时提高上升。构成：在燃烧室4和化油器7之间配置有用于加热汽化器7的蒸发室8的重力式热管10。热管10在下端的水平部分嵌入燃烧室4中的燃烧器5的下部，并且在上端的上升部分嵌入化油器7.在燃烧器5的点火时，化油器7的加热器9被供给电力以加热化油器7.在这种情况下，化油器7与燃烧室4的侧壁1分离，管道10仅具有小的厚度，因此具有小的热量容量。此外，管道10不将热量从上端传递到下端。因此，加热器9产生的热量不会传递到燃烧室4，而蒸发室8立即达到期望的温度。这会在引入蒸发室8时产生燃料和空气的混合物的即时蒸发，然后将蒸发的混合物进料到燃烧器5。

摘要： PROBLEM TO BE SOLVED: To secure necessary air flow by branching a part of the air for combustion to supply to a combustor from a manifold arranged at the top part of a combustor barrel and by supplying it to the air swirling path of the pilot burner of a high calorie gas combustor. SOLUTION: Air flow 21 blasted from a compressor flows between a flow sleeve 2 and a liner 3. The air flow 22 is distributed as the air for combustion 24 that is supplied cooling the liner 3 and as swirler air 22 for the combustion of low calorie gas that is arranged for a fuel nozzle 4, and to the air path 23 for combustion of pilot burner through an air manifold 6 that is branched from the head part of the combustor barrel. High calorie gas 11 is supplied to the fuel nozzle 4, blown out and ignited inside the combustor. The air 23 equalized inside the manifold 6 is supplied to the air path 7 inside the fuel nozzle body 5 through a connecting pipe 8. At the exit part of the fuel nozzle 4, the air 23 is blown out as a swirling flow. Therefore, without the complexity of the structure of fuel nozzle, the quantity of the air is secured and the manufacturing cost is reduced drastically.

摘要： PURPOSE:To improve combustion efficiency and ensure pilot combustion with the reduced production amount of NOx by previously setting an air-fuel ratio of a pilot burner and a mixing ratio of pilot combustion gas and premixing air within proper ranges respectively. CONSTITUTION:When an air mass flow rate of a first premixing burner 9 is assumed to be A1 and air mass of a second premixing burner 12 to be A2, a combustor 2 is constructed such that A2=0.39 to 0.8XAl holds. When a fuel mass flow rate of a diffusion burner 8 is assumed to be Fp, t:and a fuel mass flow rate of the first premixing burner 9 to be F1, the diffusion burner 8 and the first premixing burner 9 are operated until (Fp+F1)/(A1+A2)>0.020 holds. Thereafter, a fuel flow rate of a second premixing burner fuel system 202 is thrown in for the operation. Then, premixed air is mixed with a strong shearing layer formed with oppositely rotating spiral motions, and gets high temperature. Accordingly, combustion efficiency of the pilot burner is improved and combustion with the reduced production amount of NOx is ensured.

摘要： PURPOSE:To perform a transformation into NOx at a high load operation region of a gas turbine without requiring a special constitution by a method wherein at the high load operation region, a large quantity of combustion air is fed to a pre- mixing combustion section side, accompanying with the operation of a diffused air flow control valve even with a fixed quantity of combustion air. CONSTITUTION:Compressed air of a compressor 11 is introduced to a burner 12, and burnt in a combustion chamber 13. In the meantime, a combustion gas of the burner 12 is introduced to a gas turbine 10, and drives the gas turbine 10. The burner 12 is equipped with a diffused combustion section 18A which burns at both high and low load operation regions, pre-mixed combustion section 13A which burns at a high load operation region, and a valve 26 to control an air flow rate at a combustion air intake part 27. In this case, at the combustion air intake part 27, a valve 28 to control a diffused air flow rate is additionally provided. Then, at a low load operation region, the valve 28 is operated in such a manner that the combustion air volume is increased accompanying with the ascent of a load, while the valve 28 is operated in such a manner that the combustion air volume is decreased accompanying with the ascent of load at the high load operation region.

摘要： PURPOSE:To provide a premixing device for a gas turbine which can keep a mixed state of fuel and air always in its superior condition over a wide load range and in particular which is suitable for a low NOx construction by using a fuel of natural gas and the like. CONSTITUTION:A short cylindrical striking plate 37 is mounted in a main air stream between a fuel injection hole 36 of a fuel nozzle 35 and an air flow passage wall surface of a premixing flow passage 32. Even in the case that a flow speed ratio between the fuel and the air is minimum, the fuel always strikes against the striking plate 37. Accordingly, since the fuel injection flow is always dispersed at a specified position in the main air stream in the premixing device of a gas turbine combustion device, a superior mixed state can always be maintained, resulting in that the stable low NOx premixed combustion can be easily realized in a wide load range.
