The invention discloses a gas combustion device double-wall exhaust pipe and an LNG marine gas combustion device.The gas combustion device comprises an exhaust pipe inner pipe and an exhaust pipe outer pipe, the exhaust pipe inner pipe is arranged in the exhaust pipe outer pipe, the exhaust pipe inner pipe does not make direct contact with the exhaust pipe outer pipe, a combustion chamber is arranged in the exhaust pipe inner pipe, and the combustion chamber is arranged in the exhaust pipe inner pipe; the combustion chamber is provided with a fuel gas inlet, a combustion air inlet and an exhaust hole, fuel gas enters the combustion chamber through the fuel gas inlet, combustion air enters the combustion chamber through the combustion air inlet, and waste gas generated by combustion of the fuel gas is exhausted out of the combustion chamber through the exhaust hole and enters an inner pipe of the exhaust pipe. A first cooling air inlet and a second cooling air inlet are formed in the left side and the right side of the outer exhaust pipe correspondingly. The LNG ship comprises the gas combustion device. A heat insulation layer is prevented from being laid on the outer wall of the exhaust pipe, the diameter of the outer pipe of the exhaust pipe is smaller than that of an exhaust pipe with a heat insulation layer laid in the prior art, and therefore the ship space utilization rate is increased.

    本申请公开一种气体燃烧装置双壁排气管和LNG船用气体燃烧装置,本申请中的气体燃烧装置包括排气管内管和排气管外管,所述排气管内管设置在排气管外管内,排气管内管与排气管外管不直接接触,排气管内管的内部设置有燃烧室,所述燃烧室设置有燃气进口、燃烧风进口和排气孔,燃气经过燃气进口进入燃烧室,燃烧风经过燃烧风进口进入燃烧室,燃气燃烧产生的废气经排气孔排出燃烧室进入排气管内管,排气外管的左右两侧分别设置有第一冷却风进口和第二冷却风进口。本申请中的LNG船包括上述气体燃烧装置。避免了在排气管外壁敷设绝热层,排气管外管的直径小于现有技术中敷设绝热层的排气管的直径,因此本申请提高了船舶空间利用率。
