Described incoming air conduit is arranged on Gas Pipe side, and both have a certain degree at shapeα, 00≤α≤900。
Described secondary intake pipes is centered around around gas-cooker, has some apertures to lead to inside combustion chamber, and aperture forms inclination angle in the same direction with stove wall.
Having the technical effect that of this device
1. entering mixture pipe after combustion gas mixes with air, enter back into hybrid chamber (we term it joining oxygen in advance), beneficially combustion gas is sufficiently mixed with air, improves the rapid degree of burning gases.
2. incoming air conduit is arranged on Gas Pipe side, and both have a certain degree at shapeα, acceleration mixed gas is to moving ahead, and " tempering " situation that desirably prevents occurs.
3. Inlet Manifold Design becomes to tilt in the same direction, can form the effect of " eddy current " when combustion gas is burnt in combustion chamber, and burning is more abundant, improves the burning gases rapid degree in combustion chamber, and extends combustion gas residence time in combustion chamber.
4. banking fire plate contributes to controlling the speed that flame is excessive, extends the combustion gas time of staying in combustion chamber；Aperture above banking fire plate can guarantee that fraction flame passes.
5. secondary intake pipes realizes secondary air distribution, and aperture forms inclination angle in the same direction with stove wall, increases fuel gas buring and produces higher " eddy current " effect, and prevents the situation generation that air distribution puts out flame because of too drastic one time.
