Above-mentioned flow distribution plate is made up of shunting web plate and distributing damper that an applying is set together.
Above-mentioned pottery sheet upper surface evenly distributes and is provided with a plurality of rhombus projections, comprises on it and between each projection that the groove the inside is provided with manhole.
Above-mentioned pottery sheet is installed on the housing top after with the high temperature fireproof material bound edge, and uses the press strip stationary positioned.
The utility model adopts the induction tunnel that makes up after the complete built-in split drawing, dwindled machine volume, made things convenient for installation, while nozzle and the coaxial setting of induction tunnel, and be directly fixed on open " U " font nozzle holder, guaranteed that nozzle is positioned at the center and the relative position of induction tunnel, thereby the mixing of having avoided nozzle to produce because of the changeability of relative position with to the neutrality difference is inhomogeneous, in addition, leave an intersegmental crack between nozzle and the air admission hole, when combustion gas enters induction tunnel when work, can form a negative pressuren zone at the air inlet place, thereby can extract more air and enter induction tunnel, combustion gas is fully burnt, reduce the discharging of waste gas CO and NOx.
In addition, the outlet of induction tunnel is arranged on housing cavity middle part, its front is provided with the flow distribution plate of an air baffle and " Z " font, flow distribution plate wherein is made up of shunting web plate and distributing damper, such structure has guaranteed combustion gas and the abundant premix of air and mixed air is evenly distributed in cavity, fire transmission rate is fast when making burning, can not cause detonation, tempering, the surface temperature distribution of infrared burner burning simultaneously is even, its maximum temperature arrives 850-900 ℃, pottery sheet surface does not produce flaming, simple with the ultrared mode barbecue that conducts heat, to heating object have very strong penetrability and and moisture content produce to resonate, make institute's baked goods reach optimal baking effect, in order to increase ultrared swept area, be provided with a plurality of rhombus projections in addition, comprise on it and between each projection that the groove the inside is provided with manhole even distribution of pottery sheet upper surface.
Described pottery sheet is installed on the housing top after with the high temperature fireproof material bound edge, and use the press strip stationary positioned, make the limit sealing of pottery sheet and certain expansion and contraction is arranged, and when being subjected to external impact, the pottery sheet is difficult for breaking, above the housing of dress pottery sheet, be provided with the silk screen that supports by eight screws simultaneously, secondary radiation when increasing burning with this improves the thermal efficiency.
In a word, the utlity model has flame propagation speed, highest energy in the time of just can reaching burning in a short period of time, and generation high-intensity red outside line, to heating object have very strong penetrability and and moisture content produce to resonate, make institute's baked goods reach optimal baking effect, have simple in structure, easy for installation, production cost is low, the in light weight and characteristics that do not take up space.
