From the working principle, the primary air quantity and the secondary air quantity are key factors for ensuring the complete combustion of the fuel gas. For the existing gas stove combustion system, the gas is mixed with primary air before combustion, so that the primary air is considered to participate in the reaction basically and completely, and the secondary air participates in the reaction in the combustion process due to buoyancy and entrainment of high-speed jet flow of the gas, so that the secondary air does not participate in the reaction completely. On the premise of ensuring the complete reflection of the fuel gas, the total air quantity is reduced as much as possible, and the heat released by the combustion reaction is reduced to heat the redundant air, so that the heat efficiency is improved.

At present, the supplement of secondary air in a gas stove is generally realized by optimizing a fire hole structure and increasing the contact area of a fire hole and air, the effective and rapid supplement of the secondary air is difficult, particularly when a smoke outlet is reduced, the supplement of the secondary air is more difficult, a better combustion state cannot be realized, and the standard exceeding of smoke can be caused.
