Abstract

The utility model relates to a novel burner, applying for industry or civil gas appliance. The utility model is characterized in that the center of a round combusting cover is plane; the edge of the combusting cover is inclined upwards and connected with the top joint of the cylinder-shaped combusting body, and has a 45 degree angle to the top joint; a plurality of inclined blowholes are distributed evenly on the concentric circles on the edge of the combusting cover, and the centerline of the blowhole has a 50 degree angle to the vertical center plane of the combusting cover; a inverted-cup shaped nozzle with a line of vertical small holes on the side part is arranged on a plane base; a gas gap is arranged on the center part of the base under the combusting body, and is connected with a gas pipe; the all structures are combined to form the utility model. When in use, the gas flows into the inner cavity structured by the base and the nozzle through the gas pipe and the gas gap on the base, and then gets through the small holes on the side part of the nozzle to gets into outer cavity structured by the combusting cover, the nozzle and the base, and at last is sprayed out from the blowholes to combust in a shape of centralized spraying. The utility model has the advantages of simple structure, convenient manufacture and process, safe and reliable operation, good operation condition of combustion, high thermal efficiency, and long service life of the burner.

Description

A kind of novel burner

Technical field

The utility model relates to a kind of gas burner, especially for the burner of industrial combustion gas kitchen range.

Background technology

The burner that is used for the industrial combustion gas kitchen range at present, (venthole that burning covers is the direct projection shape generally can be divided into the advection burner, be the venthole center line and cover vertical central plane overlapping in circular burning) and turbulent burner (venthole that burning covers is the oblique fire shape, and promptly venthole center line and circle are burnt, and to cover vertical central plane not overlapping).The patent No. is that the high-efficiency and energy-saving type burner of ZL95246519.1 is a kind of tangible turbulent burner, the oblique arrangement of venthole that is characterized in burning and covers, the outlet combustion gas might form the poly-shape rotation of penetrating, can avoid combustion heat energy to the diffusion in space all around, improve the utilization rate of combustion gas, energy savings; Weak point is: during the angle that covers vertical central plane when oblique venthole center line and circular burning too little (such as below 15 degree), the outlet combustion gas can't form the poly-shape rotation of penetrating, combustion efficiency is close with the advection burner, cause fuel gas buring incomplete, the thermal efficiency is low, burner body and burning lid are splits in addition, and seam crossing is gone here and there fiery phenomenon often, influences service life and safety.

Summary of the invention

A kind of vortex burner that the utility model provides, simple in structure, processing and manufacturing is easy, can effectively guarantee to export the poly-shape rotary combustion of penetrating of combustion gas, and combustion gas is effective, and thermal efficiency height is easy to use, safe, and the burner life-span is long.

The novel burner of the utility model design, comprise burner body 4, burn and cover 2, it is characterized in that: burning covers 2, burner body 4 fuses, shape is similar to " straw hat ", the fiery phenomenon of string that having avoided that burning

cover

2,4 fens body structure seam crossings of burner body takes place, improve combustion conditions, improved service life; Burner body 4 bottoms are a planar circular (being convenient to base 7 fixing), and top is the annulus cylindricality, and the top is covered 2 with burning and fused; Burning is covered 2 rounded, central part is a plane, and central hole links to each other with seedling fire lid 3, and edge part presents inclined plane shape and burner body 4 tops fuse, the two angle α=(α is too little for angle for 40～60 degree, burner body 4 is too high, processing difficulties, and be placed in burning and cover the venthole 1 of 2 inclined plane shape edge parts and export combustion gas and burn near horizontal plane, the easy burn-out burner, angle α is too big, and it is too big to make burning cover 2 sizes, can not mate with size of burner hearth); Number discharge pore 1 is evenly distributed on circular burning and covers on the concentric circles of 2 inclined plane shape edge parts, be the oblique fire shape, venthole 1 center line is spent with angle β=35～60 that 2 vertical central plane are covered in burning, has guaranteed the poly-shape rotary combustion of penetrating of outlet combustion gas effectively, (β is too little for angle to improve the thermal efficiency, the outlet combustion gas can't form the poly-shape rotation of penetrating, and easily to space diffusion all around, the combustion gas thermal efficiency is low for combustion heat energy, angle β is too big, the processing and manufacturing difficulty, and venthole 1 quantity is very little, influences combustion efficiency); The shower nozzle 6 that is fixed on flat base 7 centers is " inverted cup-shape " cavitys, and Side portion has row's vertical aperture, is convenient to combustion gas and passes through; Flat base 7 central parts that are fixed on burner body 4 bottoms have a gas port that links to each other with Gas Pipe 9, and the gas port size is less than the rim of a cup size of " cup-shaped " shower nozzle 6; 2 disjunctors are covered in burner body 4, burning and shower nozzle 6, base 7 form inside and outside two closed cavities; Above-mentioned in conjunction with constituting the utility model.

Can be at the closure tip center drilling of " inverted cup-shape " shower nozzle 6, the former seedling fire tube 5 that is arranged on burner body 4 Side portions is placed between the closure tip aperture and seedling fire lid 3 of shower nozzle 6, seedling fire air inlet pipe 8 is connected on the Gas Pipe 9, according to " chimney " principle, the combustion gas of seedling fire enters Gas Pipe 9 from seedling fire air inlet pipe 8, flow into the inner chamber body of

flat base

7 and 6 formation of " inverted cup-shape " shower nozzle by the gas port at flat base 7 centers, pass shower nozzle 6 top center apertures, seedling fire tube 5 again, burn and cover 2 planar central portion apertures, at last from 3 ejections of seedling fire lid.Avoided the combustion gas of seedling fire to enter burner from burner body 4 Side portions, accessory is fragile, keeps in repair frequent inconvenience.

The angle β of 2 vertical central plane is covered in oblique fire shape venthole 1 center line and burning, preferably 40～55 degree.

During work, combustion gas enters Gas Pipe 9, flow into the inner chamber body of

flat base

7 and 6 formation of " inverted cup-shape " shower nozzle by the gas port at flat base 7 centers, pass row's vertical aperture of shower nozzle 6 Side portions again, enter burner body 4, burning and cover the outer chamber that 2 disjunctors and shower nozzle 6, base 7 form, the venthole 1 that covers 2 inclined plane shape edge parts from burning is emitted into to gather and penetrates the shape rotary combustion at last.

The utility model is compared with prior art, and its advantage is:

1. can effectively guarantee to export the poly-shape rotary combustion of penetrating of combustion gas, thermal efficiency height.

2. simple in structure, convenient processing and manufacture.

3. burner long service life.

4. safe in utilization, reliable.
