Abstract
The invention discloses a local oxygen-enriched flame warming lengthening type combustor. The local oxygen-enriched flame warming lengthening type combustor comprises a combustor body, a swirler and oxygen-enriched air pipelines. A fuel gas pipeline and the three oxygen-enriched air pipelines are arranged on the combustor body, the swirler is arranged on one side inside the combustor body, a fuel gas nozzle of the fuel gas pipeline is arranged at the position of the swirler, a combustion supporting air inlet is formed below the combustion body, combustion supporting air is fully mixed with fuel gas at the position of the swirler and then ejected to form a main flame combustion area, and oxygen-enriched nozzles of the three oxygen-enriched air pipelines are located on the upper portion, the middle and the lower portion of the main flame combustion area respectively. The local oxygen-enriched flame warming lengthening type combustor has the advantages that on the basis of the physical principle, oxygen-enriched air is reasonably added in original flames which are not fully combusted for combustion supporting, molecules in the fuel gas and molecules in combustion supporting gas are reasonably matched, the temperature of the original flames rises by reasonably distributing and utilizing added oxygen molecules, fuel is fully combusted, and energy is saved by 25%-45%.
Description
Technical field
The present invention relates to the fuel energy-saving product scope, be specially a kind of local oxygen enriched flame and heat the elongated spacing burner.
Background technology
On gas fuel boiler, the kilns such as various roller kilns, tunnel cave and various boilers, generally use fuel for natural gas, liquefied gas, coal gas, fuel oil, pure base oil, but have the inadequate shortcoming of burning always, make fuel have waste in various degree.
Summary of the invention
In order to overcome above technical problem, the invention provides a kind of local oxygen enriched flame and heat the elongated spacing burner, reasonably the insufficient flame of original burning is added to oxygenized air combustion supporting.
The present invention adopts following technical scheme to realize: a kind of local oxygen enriched flame heats the elongated spacing burner, comprise burner body, cyclone and oxygen enrichment wind pipeline, described burner body is provided with a gas pipeline and three oxygen enrichment wind pipelines, the inner side of described burner body is equipped with cyclone, the gas nozzle of described gas pipeline is located at the cyclone position, described burner body below is provided with the combustion air entrance, combustion air the cyclone place with spray after combustion gas fully mixes and form main flame combustion district; The rich-oxygen nozzle of described three oxygen enrichment wind pipelines lays respectively at the upper, middle and lower in main flame combustion district;
The beneficial effect that the present invention produces is that product of the present invention adopts physical principle, reasonably the insufficient flame of original burning is added to oxygenized air combustion supporting, makes the molecular matching in combustion gas and combustion-supporting gas more reasonable; The oxygen molecule increased reasonably increases original flame temperature under the distribution utilization; Make fuel combustion more abundant, accomplish energy-conservation 25%-45%, and reduce the purpose of discharge simultaneously.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be elaborated:
Structural representation of the present invention as shown in the figure
In figure, 1, burner body 2, gas pipeline 3, combustion air entrance 4, cyclone 5, oxygen enrichment wind pipeline 6, rich-oxygen nozzle 7, burner fixed disk
The specific embodiment
As shown in the figure, a kind of local oxygen enriched flame heats the elongated spacing burner, comprise burner body 1, cyclone 4 and oxygen enrichment wind pipeline 5, described burner body 1 is provided with a gas pipeline 2 and three oxygen enrichment wind pipelines 5, the inner side of described burner body 1 is equipped with cyclone 4, the gas nozzle of described gas pipeline 2 is located at cyclone 4 positions, described burner body 1 below is provided with combustion air entrance 3, combustion air cyclone 4 places with spray after combustion gas fully mixes and form main flame combustion district; The rich-oxygen nozzle 6 of described three oxygen enrichment wind pipelines 5 lays respectively at the upper, middle and lower in main flame combustion district;
On described burner body 1, burner fixed disk 7 also is installed, for burner body 1 and oxygen enrichment wind pipeline 5 are fixedly mounted.
The effect of each parts of the present invention is respectively:
Burner body: for the eddy flow burning-assist and add three hole spray shapes, be sown into formula rich-oxygen nozzle 6, form local oxygen enrichment, the main purpose of design is in order to allow the oxygen enrichment molecule mate the Reasonable Combustion cleaning in flame zone, avoids oxygen molecule not burn and only in kiln, makes the porcelain oxidative deformation.
The combustion air entrance: combustion air feeds thus, by cyclone 4, distribution of air flow is become to swirling eddy, and the fuel gas buring flame vortex that gas pipeline 2 is fed has been blown main flame combustion district.
Cyclone: cut apart combustion gas and the direct of combustion air contacts, combustion air is become to eddy flow, avoided that direct current is flame-out makes combustion air and combustion gas have the more time to contact mixing simultaneously, to reach sufficient combustion.
The oxygen enrichment wind pipeline: its rich-oxygen nozzle 6 adopts high refractory material 2520 stainless steels to manufacture, the oxygen-enriched combustion-supporting gas fed by oxygen enrichment wind pipeline 5 is spelled and made the site ejection by rich-oxygen nozzle 6, make 50% some oxygen enriching burning-aid of the main flame of the combustion-supporting burning of original normal air, increase flame temperature.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure partly are known technology.
