As shown in Figure 1, the burner 1' is located above the panel 2', and the secondary air hole 3' is also located above the panel 2', and the solid line arrow part is high-temperature flue gas (CO ₂ , CO, H ₂ O, NOX etc.) discharge path. The dotted arrow part is the supplementary path of secondary air. The two appear to intersect, and part of the high-temperature exhaust gas flows back into the secondary air port to participate in the combustion reaction. Due to the mutual interference between the two, it is impossible to add enough oxygen to participate in the combustion reaction, and the reaction is incomplete, resulting in excessive CO emissions after combustion. On the other hand, when the distance between the top of the bracket and the panel is too large, the high-temperature flue gas is too divergent, so that the bottom of the pot and the flame of the burner cannot fully exchange heat, which affects the thermal efficiency of combustion, and the utilization rate of heat is low.
