As shown in fig. 1 and 2, in a preferred embodiment, the adjustable dual burner of the present invention mainly comprises a main burner 1, an extension burner 2, a fixing pin 3, an air inlet pipe 4, and a support member 5. Wherein, main part combustor 1 includes air intake portion 11 and connecting portion 12, and intake pipe 4 is connected with air intake portion 11, and combustible gas accessible intake pipe 4 gets into air intake portion 11. The connecting parts 12 are symmetrically arranged on two sides of the air inlet part 11, the connecting parts 12 are used for connecting the extension burner 2, the extension burner comprises two first combustion pipes 13 which are arranged in parallel, and the first combustion pipes 13 are communicated with the air inlet part 11.

The number of the extension burners 2 is two, and the two extension burners 2 are respectively disposed at both sides of the main body burner 1. Each extension burner 2 includes two second combustion pipes 21 arranged in parallel, and an arc-shaped combustion piece 22 arranged between the second combustion pipes 21, and both ends of the arc-shaped combustion piece 22 are respectively communicated with the two second combustion pipes 21. Wherein the outer diameter of the second combustion pipe 21 is matched with the inner diameter of the first combustion pipe 13, and the second combustion pipe 21 is inserted into the corresponding first combustion pipe 13 and slid along the first combustion pipe 13 so that the extension burner 2 can be horizontally extended and contracted with respect to the main body burner 1. Through flexible extension combustor 2, the length of adjustable combustor to match the oven of different models, improve the suitability of combustor.
