Description
The utility model relates to the burner of burning gases fuel, is a kind of home-use and gas kitchen ranges catering trade special use of being applicable to.
Though burners in prior is simple in structure, burning is complete, and based on the smoke convection heat exchange, its thermal efficiency is on the low side, the overwhelming majority＜55%; The flame temperature height, NO
xDischarging is high, is generally 80ppm～500ppm; Also there is combustion noise.
Commercially available porous ceramic plate burner, heavy, crisp and frangible, difficult point is fiery, easy flame-out, combustion instability, adjustable range is little, and thermic load is little.The surface heat intensity of bimetallic net burner is near the ceramic wafer burner, and more fragile than ceramic wafer burner.Commercially available metal fiber burner is because of the restriction of fiber material, and there is high temperature deformation in the high-temperature machinery intensity difference, needs under fibrage support to be set; Gas permeability is poor, and drag losses is big, incomplete combustion, and the CO discharging exceeds standard, and needs to be provided with in addition on combustion front aperture; Fibrage compresses with the burner cavity and is connected, and spatial volume is big.
The purpose of this utility model is the weak point that overcomes existing kitchen range, and a kind of light-duty, no high temperature deformation, big, big, energy-efficient, the oligosaprobic burner of surface heat intensity of high-temperature machinery intensity are provided.
The technical solution of the utility model is:
Burner is by spraying entraining type blender 1, cylindrical metal housing 2, combustion front 3 and enclosing formula screening heat shielding 4 and form, it is integrally welded to enclose formula screening heat shielding 4 and cylindrical metal housing 2, burner combustion face 3 is welded on the metal shell 2 for containing yttrium iron Cr-Al alloy fleece; Combustion front is made into disc, anchor ring, recessed spherical crown surface, the recessed playing surface of the table or recessed round table surface according to combustion power size and heated part shape; Be provided with auxiliary air import 5 according to actual needs, make the low-pressure fuel injection blender 6 of auxiliary fiery usefulness, make auxiliary fire with containing yttrium iron Cr-Al alloy fleece 7.
Enclose formula and hide heat shielding 4 with round table-like conical surface encirclement, its underpart will seal around the burner, and is provided with some adjustable perforates.Enclose formula and hide heat shielding 4 and prevent that cold air from too much sneaking into, adjust the soakage of auxiliary air according to combustion gas calorific capacity size.
The utility model is compared with the burners in prior tool, and its advantage mainly embodies and is:
1. energy-conservation: the thermal efficiency exceeds more than the 9.8-11.6%, and the energy conservation rate reaches more than 16.3% relatively.
2. environmental protection: NO
xDischarge capacity reduces 50～66.7%; The concentration of CO is 350-500ppm in the combustion product, is lower than household gas utensils standard GB16410-1996 setting 500ppm.
3. safety: containing yttrium iron Cr-Al alloy fleece provides bigger combustion front face, and the fuel gas buring process is had the catalytic action of physics and chemistry, is stable ignition source, safe in utilization.
4. durable: because the gadolinium-containing alloy fleece is high temperature resistant and anti-oxidant and corrosion resistance is good, so be difficult for deteriorating long service life.
Below in conjunction with accompanying drawing the utility model is further described.
