[0035] In the above embodiment, specifically, please refer to Figure 2 , two groups of flow guide plates 501 are installed in the inside of combustion chamber 5, and the flow guide plates 501 are located at the top of fire inlet pipeline 502, when the flame is sprayed from fire inlet pipeline 502, the two groups of flow guide plates 501 located above fire inlet pipeline 502 guide the flame.
[0036] In the above embodiment, specifically, please refer toFigure 3 The two groups of guide plates 501 are combined in a V shape, and a certain distance is provided between the two groups of guide plates 501.
