The utility model relates to the continuous flame vortex formula of a kind of used for industrial furnace internal combustion type oil burner, and it belongs to the burner class.
Existing used for industrial furnace continuous internal combustion flame burner is by compositions such as shell, burner inner liner (combustion chamber) and fuel injection nozzles.In order to improve thermal technology's quality, people have done a large amount of work around the improvement of fuel injection nozzle and distribution scheme preferred for a long time.On the distribution scheme, traditional modal scheme is: most air centers on fuel injection nozzle with stronger eddy flow air inlet.There are two problems in this distribution scheme: one, and partly mist of oil can be got rid of to flame tube wall by near the strong eddy flow the fuel injection nozzle, thereby coking, carbon deposit phenomenon take place; Its two, the burner inner liner barrel does not have more, stronger air-flow protection, and is overheated easily, the material that is directed at burner requires high.
In order to address the above problem, there is the inventor to start with near the swirl strength that weakens the fuel injection nozzle, developed a series of burner.In July nineteen eighty-three, the G type burner with high efficiency that Zhuzhou lotus pool shop machinery plant sells is exactly wherein a kind of.It is made up of burner inner liner, shell, fuel injection nozzle, annular plate washer etc.Burner inner liner comprises stack shell and end plate, and burner inner liner stack shell middle part is the converging portion of a taper, and nearly fuel injection nozzle end is a large cylinder, and nearly flame end is a little cylinder, has air admission hole or groove on converging portion and the little cylinder.Described air admission hole or groove are big more from the near more area of flame end; End plate is one to have the sandwich plate of fuel injection nozzle block set installing hole on it, is made up of backboard and panel, and backboard is welded on the stack shell, and has the air inlet sieve aperture; Panel excircle and burner inner liner stack shell inwall leave the air inlet annular space, the gross area of described air inlet annular space be on the stack shell pore that drives into, the groove gross area 15.9%.This burner has been abandoned near the practice that in the range of atomization, combustion chamber (being flame root, the fuel injection nozzle) infeeds most air, has adopted the segmentation technology of supplying gas, and promptly only supplies with few partly air capacity near the fuel injection nozzle, and most air is supplied with along length of flame segmentation.Simultaneously this burner to air admission hole or groove the distribution on burner inner liner also done preferably.
Development on this basis, the content of a kind of burner that upgrades is that CN85200214 is disclosed, this burner also is made up of shell, burner inner liner, fuel injection nozzle, annular plate washer etc., burner inner liner comprises stack shell and end plate, stack shell by the different cylinder of two diameters with a gap the phase intussusception form, intussusception length is 20～25 millimeters, and last intussusception length is 30～60 millimeters.One convergent cone tube is arranged on the large cylinder of described cylinder, and large cylinder has 1～2 row radial air inlet hole near the conically shaped position, has air admission hole or groove on the conically shaped, and described air admission hole or groove are big more from the near more area of flame end.End plate is one to have the sandwich plate of fuel injection nozzle block set installing hole on it, it is welded with rib by panel and backboard, backboard is welded on the stack shell, panel excircle and burner inner liner stack shell inwall leave annular space, have the air inlet sieve aperture on the backboard, have the air inlet annular groove on the panel, the gross area of annular space is 7～17% of stack shell enterprising compression ring crack and air admission hole, the groove gross area between air inlet annular groove of being opened on the described panel and panel and burner inner liner stack shell inwall.Burner inner liner and shell are eccentric in addition installs.Such burner, the G type burner with high efficiency of Zhuzhou lotus pool shop machinery plant production and sales is compared with July nineteen eighty-three, and main difference is to adopt the intussusception annular space to replace part air admission hole or groove on the burner inner liner stack shell and burner inner liner and the eccentric installation of shell.The inventor tries hard to adopt the intussusception annular space to strengthen the protective effect of auxiliary air to burner inner liner corresponding site inwall; Try hard to make burner inner liner that a comparatively balanced air pressure field can be arranged on every side by the off-centre installation.Even now, still there is following problem in the disclosed burner of CN85200214: the one, near sections of atomization (fuel injection nozzle) air inflow is very few, is difficult to the atomizing effect that reaches satisfied when oil is relatively poor.The 2nd, end plate is that sandwich is comparatively complicated.The 3rd, the burner inner liner opposite shell is eccentric installs, and can not set up a comparatively balanced air pressure field around burner inner liner, and the combustion efficiency of burner is had certain influence.
For the 3rd above-mentioned problem; the solution that Russian Patent SU1195-135 proposes is: install one on the burner inner liner stack shell of air admission hole additional by sealing of flame end having; the other end has the cylindrical shape protective cover of oblique otch; because the effect of protective cover, make the air pressure field of around burner inner liner, setting up an equilibrium.Not talkative this be not a kind of efficient ways, but increased structural complexity.
The purpose of this utility model is to provide a kind of used for industrial furnace oil burner of novelty, and its relative prior art structure is more simple, and problems of the prior art are solved.
Main points of the present utility model are to have done on the scheme more reasonably to select spraying to of distribution and air-flow, on the distribution ratio, the auxiliary air amount that infeeds from the base plate air admission hole is 1～6% of a whole air quantity delivered, the air capacity that infeeds from burner inner liner oil gas mixer is 38～51% of a whole air quantity delivered, both add up, the air amount of infeeding of whole oil gas mixing portion (being the fuel injection nozzle near zone) is 32～52% of a whole air quantity delivered, and all the other air of 48～68% are supplied with along the length of flame; On air-flow sprays to, the utility model has been offered some length on burner inner liner oil gas mixer be m, width is the tangential admission groove of n, and L is more little for the near more converging portion mutual spacing of these tangential admission grooves, and is big more with the near more converging portion area of area that guarantees the tangential admission groove of being opened.The air that sprays into from these tangential admission grooves forms one adherent eddy flow in burner inner liner.And near more flame end eddy flow is strong more.
The utlity model has following characteristics: one, the air demand of oil gas mixing portion is bigger, prolong and used traditional distribution scheme that oil gas mixing portion is supplied with the design philosophy that more air capacity helps fuel-oil atmozation, and the part fuel oil that traditional distribution scheme exists is thrown toward barrel and the coking, carbon deposit and the burner inner liner inwall that cause do not have stronger, more air-flow protection, easy overheated problem, spray to by changing air-flow, promptly on the oil gas mixer, offer the tangential admission groove and solve; They are two years old, the utility model is because oil gas mixing portion air demand is bigger, leading simultaneously air-flow is the eddy flow of one attached wall, this strand eddy flow makes central authorities of oil gas mixing portion region form the area of low pressure, cause partly high-temperature gas backflow and form turbulent flow, created good environment to fuel-oil atmozation with the auxiliary air that infeeds from base plate.Its three, from the attached wall eddy flow that oil gas mixing portion infeeds, make that also the leading air-flow in the whole burner inner liner is the eddy flow state, this makes that burner inner liner ambient air pressure field is unbalanced, and the influence of thermal technology's quality of oil burner is reduced greatly.
