GAS COMBUSTION DEVICE

PURPOSE:To make a uniform distribution of an entire thermal radiation pipe by a method wherein a catalyst and a thermal sensing means are arranged in a partial passage of the thermal radiation pipe and a valve which is opened when a sensed temperature of the thermal sensing means is increased is arranged in the remaining flow passage. CONSTITUTION:The gas combustion device is comprised of a partition member 21 dividing a thermal radiation pipe 8 into a plurality of flow passages in an axial direction of the pipe, a catalyst 23 arranged in a partial passage of the partitioned flow passages divided by the partition member 21, a thermal sensing means 24 arranged near the catalyst 23 and a valve 26 which is opened when a temperature sensed by the thermal sensing means 24 arranged in the remaining passages is increased. With this constitution, it is possible to make a uniform distribution of temperature over an entire thermal radiation pipe.
