Abstract

The utility model relates to a pressurized energy-saving gas burner. A body adopts a thin columnar casing which is used for raising the pressure and the temperature of a mixing chamber and enhancing the ability of controlling small fire, the upper surface of the casing is a far infrared ceramic board, the middle part of the casing is divided into two mixing and preheating cavities and a diffusion cavity by two partition boards with a plurality of groups of holes distributed according to a concentric circle and the bottom face of the cavity of the casing, the two mixing and preheating cavities and the diffusion cavity are used for raising the gas mixing and preheating function of the burner, and the cavity is connected with a venturi pipe, the end part of which is provided with a needle type jetting valve for controlling gas volume.

Description

Pressurized energy-saving gas burner

A kind ofly making the cooking stove of fuel with fuel gas (coal gas, liquefied petroleum gas), is a kind of comparatively desirable boosting energy-saving burner for small home.

Current general family, the flame orifice plate of the cooking stove of common use metal arranged with two kinds of far-infrared ceramic stove sheets, in the use, because combustion gas and air undercompounding, mist gives that hot temperature is not enough, and fuel gas buring is insufficient, and flame temperature is not high, cook required time of cooking is longer, and the thermal efficiency is generally below 58%.Use the cooking stove of metal flame orifice plate, pot, spoon bottom also have the carbon distribution phenomenon.The cooking stove of far-infrared ceramic sheet, because the mixing chamber volume is bigger, after mist sprayed into, relative pressure was low, during burning, the flame spray power that makes progress is little, in addition, is not easy flame is controlled to less.

In order to make full combustion of fuel, improve the thermal efficiency of stove and accessory, fuel savings, the utility model has provided a kind of boosting energy-saving burner.

For reaching this purpose, structurally at first should guarantee to strengthen the speed that fuel gas flows into burner.Adopt pin type injection valve, the switch that has increased injection valve falls to the pressure between the nozzle, strengthens the air ability of entrainmenting.Adopt Venturi tube version, trunnion is long slightly, and gas can better be mixed.

Secondly, for increasing the pressure of mixing chamber, take to reduce mixing chamber volume way, volume is at 500～600cm ³For replenishing and improve the mixing ability of mixing chamber, be separated into three cavitys in upper, middle and lower by two dividing plates simultaneously, hot chamber is given for mixing in bottom and middle part, and top is diffusion chamber.Mist enters the bottom mixing and gives in the hot chamber, has only the holes that distribute by concentric circles by three groups on the lower clapboard, just can enter the middle part mixing and give hot chamber; Three groups of holes of lower clapboard are middle macropore, and both sides are aperture; The main aperture gas flow rate increased in the middle of the both sides aperture can make.Upper spacer has four groups of Kong Qun by the pore size unanimity of concentric circles distribution, staggers in three groups of holes of per two groups of positions and lower clapboard.Then, mist sprays through a dividing plate concentric holes, enters diffusion chamber, flows into the flame hole burning on the ceramic wafer.Because the height of the far infrared stove and accessory of the more common use of height of cavity is low, so temperature improves in the cavity, and two middle dividing plates have increased the surface area that mist conducts heat.Therefore mist give hot temperature height, the gasification reaction of hydrocarbon quickens, and lays the first stone for flammable composition in the mist fully burns, thereby reaches the purpose of saving combustion gas, the solar term rate reaches more than 20%.

Whole burner body of heater adopts the irony plate stamping and forming, and is welded into whole body of heater with Venturi tube (being welded with the plate shaping), and also available iron casting is shaped.Two dividing plates are plate stamping part, are fitted in the housing inner chamber respectively; The infra-red china plate is bonded on the body of heater with heat-resistant adhesive.Folding three legs are set, the supporting pot spoon along branches such as body of heater peripheries.Three fixed feet in bottom are stamping parts and body of heater spot welding.

Now the accompanying drawing by embodiment more clearly illustrates concrete structure situation:

Fig. 1 is the front view of burner

Fig. 2 is the vertical view of burner

It is that 150 millimeters Venturi tubes (2) are mixed with the burner bottom and given hot chamber (3) and connect by length that fuel gas enters pin type injection valve (1) by pipeline; The bottom is mixed and to be given hot chamber (3) and mix with the middle part and give hot chamber (4), last three layers to press concentric circles distribution hole faciation logical (on 118 millimeters circles of outer radius by lower clapboard (8), the hole of 30 φ 6～φ 3, the hole that 16 φ 6～φ 3 are arranged on 78 millimeters circles of nexine radius, middle radius is the hole that 15 φ 12 are arranged on 33 millimeters the circle) middle part mixes and gives hot chamber (4) and top diffusion chamber (5) and lead to by concentric circles distribution hole faciation that (diameter is on the circle of 125 millimeters of φ 40 one φ 5 holes to be arranged, and diameter is on the circle of 145 millimeters of φ 50 one φ 5 holes to be arranged for last four layers by upper spacer (7); Diameter is on the circle of 60 millimeters of φ 25 one φ 5 holes to be arranged; Diameter is that 15 one φ 5 holes are arranged on 40 millimeters circles of φ) combustion gas and air gas mixture be exactly to finish mixings, give heat and enter far infrared ceramic plate flame hole and burn along this path.Lower clapboard (8) is positioned at apart from 16 millimeters places of base plate; Upper spacer (7) is apart from (8) 5 millimeters of lower clapboards; Far infrared ceramic plate (6) bottom surface is apart from (7) 6 millimeters of upper spacers.40 millimeters of burner body of heater (9) height; Be welded on the body of heater (9) by circumference uniform distribution three movable legs of 3 punching presses (10) point on the body of heater.Leg (11) far infrared ceramic plate (6) diameter of three punching presses of body of heater (9) bottom weldering is φ 170.
