Abstract
The utility model discloses a novel total hot-air fuel oil nozzle with automatic proportion control, which is improved on the basis of the original total hot-air fuel oil nozzle with automatic proportion control. A cylindrical adjustor for the length of flame is arranged in a shell body, and a rectangular channel is arranged in the adjustor. An air nozzle is arranged on a transport steam tube, and the air nozzle and the inner sleeve of a corrugated tube are formed into integration through a pull rod and the end connector of the pull rod. The air volume is high air temperature, and the air temperature can reach 500DEG C. The proportion between air and fuel oil can be automatically controlled, and the low-pressure air and the transport high-pressure steam are doubly atomized. The utility model does not leak oil and is not coked, and the flame length can be adjusted. Ignition is easy, and maintenance is easier. The utility model can be used in the forging heating furnace, the rolling steel heating furnace, the heat treating furnace, the building material kiln and others various industrial furnaces.
Description
The utility model is a kind of industrial furnace oil burner.
At present comparatively advanced in the oil burner that industrial furnace uses is that full hot blast automatic ratio is regulated fuel nozzle, the whole air quantity of this fuel nozzle are high wind-warm syndrome, wind-warm syndrome can be up to 500 ℃, automatic ratio is regulated between air and fuel oil, low-pressure air and accompany the dual atomizing of high steam, oil-proof, noncoking, yet, the nozzle of this structural design also has unsatisfactory place at aspects such as technological operation, maintenance of equipment, combustion stabilities, and the length of flame is non-adjustable, requires further improvement in actual the use and perfect.
The purpose of this utility model is to improve existing full hot blast automatic ratio and regulates fuel nozzle, makes its design more reasonable, and not only igniting is easy, and flameholding is structure-reinforced, weight saving, and use, easy to maintenance, and have the new length of flame to adjust.
The utility model is by housing (1), air nozzle (2), oil nozzle (3), oil pipe (4), accompany steam pipe (5), length of flame adjuster (6), steam inlet interface (7), corrugated stainless steel tubing (8), pull bar (9), air, oil ratio example adjuster (10), bonnet (11), oil pressure indicator (12), cover (13) in the bellows, pull bar connection sheet (14), spring (15), bellows overcoat (16), base (17), oil-in interface (18), air intake interface (19), becket compositions such as (20).
Describe structure of the present utility model and handling characteristics in detail below in conjunction with accompanying drawing.
The utility model heart position therein is provided with an oil pipe (4), parallel oil pipe is provided with bushing type and accompanies steam pipe (5), at the oil pipe head oil nozzle (3) is housed, air nozzle (2) is in accompanies on the steam pipe, and can before and after accompanying on the steam pipe, slide, sliding distance is 20-30mm, actual internal area when flowing out to change air, flow is changed, fuel oil flows out from oil pipe, runs into helical flow, atomizing for the first time takes place greater than the steam of accompanying of 100 meter per seconds in speed, rotatablely move along oil nozzle pyrometric cone body wall then, atomizing for the second time takes place with air stream.Air nozzle (2) forms as one by pull bar (9) and pull bar connection sheet (14) with the interior cover of bellows (13), when oil pressure improves, the linear increase of amount of fuel, compress corrugated stainless steel tubing (8) simultaneously, cover in the bellows is moved backward, by pull bar connection sheet and pull bar air nozzle is also moved thereupon backward, combustion air volume also is linear to be increased, keeping under the constant situation of blast, air capacity is automatically regulated pari passu, and its ratio is to regulate by the rotatable air, the oil ratio example adjuster that are installed on the bellows overcoat (16).By rotating the shift length that can produce the 5-10 millimeter, when moving forward, compression spring (15), simultaneously cover in the bellows is also moved forward, reduce the circulation of air sectional area that air nozzle forms, also just reduced air mass flow, changed the ratio of air, oil.
In housing (1), columnar length of flame adjuster (6) is arranged, rectangular passage is wherein arranged, when air stream is flowed through passage, rotate, can make the entering angle of air stream be adjusted to 45 ° by 0 ° with cylinder, at this moment the swirl strength of air-flow adjusts to 1.6 by 0, form the different lengths of flame, angle is bigger, and swirl strength is bigger, the length of flame is shorter, not only make igniting easily but also during burning flame also stable.
Connect with ring flange and air pipe line at air intake interface (19), spray nozzle front end is an air outlet slit, and shrink at-60 ° of angles at 45, improves air velocity to 80 meter per second.Rear end and base (17) connect.Oil pipe line and oil-in interface (18) link on base, and steam pipework and steam inlet interface (7) link, and have also had the bonnet (11) of sealing and protective effect to connect on base.Afterbody at bonnet has oil pressure indicator (12), during operation, can show the size of oil pressure, makes application convenient.
Course of action of the present utility model is: when needs increase heating demand, fuel pressure can be improved, pass through capillary channel, amount of fuel is increased linearly, bellows is compressed simultaneously, pushing drawing rod, air nozzle is opened, the circulation area of air increases, under the certain situation of blast, also increase combustion-supporting air quantity linearly, balance each other until the active force of oil pressure increase and the reaction force of spring, at this moment promptly constitute between air and the oil automatically proportioning pari passu, form burning under the best circumstances.The excursion of oil pressure is 50KPa-300KPa, and blast is fixed on 7KPa, and wind-warm syndrome can change in 350-500 ℃ of scope, and oil viscosity is in 5 ° of-8 ° of scopes of Engler viscosity, and accompanying steam pressure is 50-100KPa.
Because the utility model is the low-pressure air atomizer, also has the high steam of accompanying atomizing, belongs to dual atomizer, the oil atomization effect is excellent, when burning capacity changes, can fully automatically guarantee completing combustion, air capacity reaches best combustion efficiency near theoretical value.
Because it is moving sealing element that the utility model adopts corrugated stainless steel tubing, becket is that this special sealing mechanism of static seal element and steam are accompanied, can use light oil, heavy oil, residual oil and the various combustion oils of high viscosity residue wet goods, not only flexible movements are oil-proof, and also can guarantee during in wind-warm syndrome up to 500 ℃ oil-proof, reason deposit carbon and produce fault such as spout coking when pipeline blockage and ejection take place not simultaneously.
Because it is rotatable that air of the present utility model is introduced, its swirl strength can change by length of flame adjuster, thereby the length of flame can be adjusted according to arts demand.
Because the utility model adopts air, oil ratio example adjuster, gives pre-applied force of spring, and the ratio between air and the oil can be adjusted, needs during with the different combustion atmosphere of technological requirement are easy and simple to handle when adapting to ignition operation.
Because housing of the present utility model is welded by steel plate, tubular for threeway, comparable cast iron is structure-reinforced, weight saving.During maintenance, available steel wire inserts, and mediation oil pipe and oil nozzle clean, and maintenance is more prone to.
The utility model can be widely used in forge furnace, heater for rolling steel, heat-treatment furnace, building materials kiln and other various industrial furnaces.
Accompanying drawing is nozzle arrangements figure.
