摘要： PROBLEM TO BE SOLVED: To safely and completely combust fuel gas irrespective of a supply flow rate of the fuel gas.
SOLUTION: An internal cylinder 10 for defining a first flow passage 45 is provided outside a nozzle 20 including a main nozzle hole, and an introduction flow passage is defined between the nozzle 20 and the internal cylinder 10. A gas introduction hole is formed in a peripheral wall of the internal cylinder 10, opposing the main nozzle hole and putting the introduction flow passage therebetween. An external cylinder 12 is provided outside the internal cylinder 10 for defining an external flow passage, and the external flow passage is defined into second and third flow passages 55, 56 by a partition cylinder 54. When a supply flow rate is low, the fuel gas enters the first flow passage 45 through the introduction flow passage, entrained on an air stream flowing through the introduction flow passage, while, when the supply flow rate is increased, the fuel gas surpasses the air stream flowing through the introduction flow passage and further flows into a second flow passage 55 and a third flow passage 56 through the gas introduction hole in this order.

摘要： PROBLEM TO BE SOLVED: To assure stability upon low load combustion.
SOLUTION: Combustion air is supplied into a case 3, and fuel gas such as urban gas is supplied to a nozzle 20 through a flow rate control valve. Concentric swirlers 36, 37 are disposed downstream a nozzle hole of the nozzle 20. Upon high load combustion the fuel gas is injected from a first nozzle hole 34 of a large diameter portion and from a second nozzle hole 40 of a cone 22, and reaches not only the central swirler 36 but also the surrounding swirler 37 to permit the high load combustion to be performed in a combustion chamber disposed downstream the swirler. The fuel gas injected from the first and second nozzle holes 34, 40 upon the low load combustion where the fuel gas is a low flow rate flows near the axis of the nozzle structure and is guided to the central swirler 36, whereby concentration of the fuel gas in the central swirler 36 is prevented from being lowered to keep a stable combustion state unchanged.

摘要翻译：要解决的问题：确保低负荷燃烧时的稳定性。解决方案：将燃烧空气供应到壳体3中，并且诸如城市气体的燃料气体通过流量控制阀供应到喷嘴20。同心旋流器36,37设置在喷嘴20的喷嘴孔的下游。在高负载燃烧时，燃料气体从大直径部分的第一喷嘴孔34和锥体22的第二喷嘴孔40喷射，并到达不仅中心旋流器36而且围绕旋流器37，以允许在设置在旋流器下游的燃烧室中进行高负荷燃烧。在燃料气体为低流量的低负荷燃烧时，从第一喷嘴孔34和第二喷嘴孔40喷射的燃料气体在喷嘴结构的轴线附近流动并且被引导到中心旋流器36，由此燃料浓度中央旋流器36中的气体被防止降低以保持稳定的燃烧状态不变。

摘要： PROBLEM TO BE SOLVED: To improve a cooling performance of a cylinder having a cooling structure.
SOLUTION: A plurality of protrusions 38 are provided sprinkled at an interval in a circumferential direction 40 and an axial direction 41 on an outer periphery of a combustion cylinder body 25, and further the protrusions 38 are deviated in a zigzag manner in the directions 40 and 41 of the body 25 and disposed. Cooling gas passages 39 extended obliquely at the respective protrusions 38 so as to approach an axis of the body 25 to be extended along the direction 41 and directed toward a downstream side of a cooling gas flow. Since a surface area of the body 25 is increased by the protrusions 38, a cooling effect of cooling air is improved. Since the protrusions 38 are disposed in the zigzag manner and the passages 39 are respectively provided in the protrusions 38, the cooling air is smoothly introduced into the passage 39. The air passage through the passage 39 flows along an inner periphery of the body 25 to lower a temperature of combustion as brought into contact with the inner periphery.

摘要翻译：要解决的问题：提高具有冷却结构的气缸的冷却性能。解决方案：在燃烧筒体25的外周上沿圆周方向40和轴向方向41间隔地设置有多个突起38，并且突起38进一步以锯齿形的方式在方向40上偏离， 41的身体25并处理。冷却气体通道39在各个突起38处倾斜延伸，以便接近主体25的轴线，以沿着方向41延伸并指向冷却气流的下游侧。由于主体25的表面积被突起38增加，所以冷却空气的冷却效果提高。由于突起38以锯齿形的方式设置并且通道39分别设置在突起38中，所以冷却空气被平滑地引入通道39.通过通道39的空气通道沿着主体25的内周流动到降低与内周接触的燃烧温度。
