Degree.It will make a fire mouth and cleaning door be arranged on the relatively low burner hearth coaming plate in position, reduce the difficulty of igniting, convenient observation fire
Scorching fired state, while it is also convenient for the ash in clearing furnace.
Further, the circle of top connection one of the flue turns square conduit, and the circle turns square conduit and connected by a square flange
Output channel is connect, the flue bottom is by a circular flange with being connected at the top of the burner hearth coaming plate.Connected by flange
The mode connect make to connect between workpiece it is easy for installation, the engineering time can be reduced, improve operating efficiency.
Further, the setting height(from bottom) of the square flange is slightly below the top of the ventilating duct so that the flue, circle turn
Square conduit and square flange are in the ventilating duct.Rational height control can effectively reduce flame end effect.
Further, a columnar return air inlet shroud is fixedly connected with the top of the ventilating duct, the return air inlet shroud passes through
Top plate is simultaneously fixed on top plate.Return air inlet shroud connection extraneous air is easy to improve the radiating efficiency of flue.
Preferably, the ventilating duct and the flue are cone, and the burner hearth coaming plate is cylindrical shape.
Preferably, the wall body of the flue is made using the stainless steel plate of δ 3.5mm heat-and corrosion-resistant.Stainless steel
Harden structure intensity is big and corrosion-and high-temp-resistant.
Preferably, some flow deflector spaced sets.
Compared to prior art, the beneficial effect of this case is：
Its flue setting of the heat exchanger of this case is tapered, more presses close to shape of the flame in spontaneous firing, makes flue
Be heated evenly up and down, up and down simultaneously expanded by heating, also simultaneously cooling meat, effectively reduce metal flue heating power corrode make
With lower generation creep and stress fracture phenomenon, further, flue and ventilating duct are that conical design can also reduce production materials, are subtracted
Low production cost；Flow deflector is provided with ventilating duct inwall, when the air of outer low temperature passes through return air inlet shroud, from ventilating duct top
When portion flows to ventilating duct bottom, the time that outer low temperature air flows through furnace outer wall, low temperature can be increased through the deflecting of flow deflector multistage
Air can fully contact with flue, effectively improve the radiating efficiency of flue, and then improve the heat exchanger effectiveness of flue.
