Coke oven raw gas conveying structure

The invention relates to a coke oven raw gas conveying structure which comprises a raw gas conveying pipeline and a high-temperature gas heat tracing bustle pipe, the high-temperature gas heat tracing bustle pipe and the raw gas conveying pipeline are coaxially arranged on the periphery of the raw gas conveying pipeline in a sleeving mode, and the pipe wall of the high-temperature gas heat tracing bustle pipe is sequentially provided with a fireproof structure layer, a heat insulation layer and a rigid shell from inside to outside. And a positioning support piece is arranged between the raw gas conveying pipeline and the high-temperature gas heat tracing bustle pipe. The high-temperature gas for heat tracing is introduced into the annular space between the raw gas conveying pipeline and the high-temperature gas heat tracing bustle pipe, so that the problem that tar gas in the raw gas is adhered to the inner wall of the pipeline due to temperature drop can be avoided, and heat loss of the raw gas and even heat
