When the device is used, one end of the first burner pipe 1 can be used as an air inlet end, an ignition mechanism is arranged on one outer side of the end, after partial gas holes 4 on the side are ignited through the ignition mechanism, gas is blown into the first burner pipe 1, the second burner pipe 2 and the connecting pipe 3, and then the gas is continuously sprayed out from all the gas holes 4 and contacts with oxygen to burn, and as the gas holes 4 are distributed on the first burner pipe 1, the second burner pipe 2 and the connecting pipe 3 shown in the figure 1, compared with the prior art, the arrangement area of the plurality of gas holes 4 is larger, so that the device can be designed to be denser, and heat with larger power is provided. Moreover, in the ignition process, the flame starts to burn from one end of the first burner pipe 1, and when the flame passes through the middle of the arc-shaped part, the flame needs to be divided into two paths, namely the second burner pipe 2 and the first burner pipe 1 at the other end, so that insufficient gas supply can be caused, and the first burner pipe 1 and the second burner pipe 2 can be filled with gas only by blowing the gas for a period of time. Therefore, in order to accelerate ignition and rapidly realize high-heat output, the connecting pipe 3 is communicated between one end and the other end of the first burner pipe 1, so that after ignition, gas can be conveyed to the other end of the first burner pipe 1 through the connecting pipe 3, then the gas holes 4 on the first burner pipe 1 and the connecting pipe 3 are preferentially ignited, peripheral heat is formed, and then the second burner pipe 2 is gradually ignited to increase burner combustion power.
