[0032] In the application, in actual use, oil liquid is injected from the outer oil pipe 21, the oil liquid enters the oil injection ring pipe 12 through the single oil injection pipe 14, then enters each outer pipe 4 through each quick-through pipe 13, passes through the connecting pipe 5 to enter the inner pipe 3, then enters the inner ring pipe 9, and finally is discharged by the inner discharge pipe 11, realizing the flow transfer of the oil liquid. The oil liquid is transferred in the outer pipe 4 and the inner pipe 3, and the igniter 2 burns and heats the inside of the furnace body 1, so that the oil liquid is sufficiently heated during the transfer process. The oil liquid is limited to enter the outer pipe 4 on the outside and then enter the inner pipe 3 on the inside. The oil liquid sufficiently utilizes the pipeline space inside the furnace body 1 and is sufficiently heated, and can be transferred from the outside to the inside, so as to avoid pipeline damage caused by too large temperature difference between the oil liquid and the pipeline, improve the service life of the pipeline, and ensure that the oil liquid temperature discharged from the furnace body 1 is consistent and does not differ due to the temperature difference between the inside and the outside, thereby ensuring the stable and effective oil supply temperature.
