Abstract
An oxygen-enrichment nozzle special for an oil field heating furnace and a heating furnace fire tube combined with the same belongs to matched components of heating equipment special for the oil field. The oxygen-enrichment nozzle special for the oil field heating furnace is in the long tube shape and comprises a straight tube section and a conical tube section, wherein the conical tube section contracts toward an outlet to form the nozzle, and an inlet is formed at the end edge of the straight tube section. The heating furnace fire tube comprises a heating furnace fire tube end face and a burner nozzle, wherein a plurality of oxygen-enrichment nozzles are evenly distributed on the heating furnace fire tube end face to provide oxygen-enrichment air. The oxygen-enrichment nozzle has an injection function, and accordingly oxygen-enrichment air can enter into the heating furnace fire tube at a certain speed and angle, thereby supporting combustion, lengthening flame, preventing the fire tube wall from being burned and reducing non-combustible gas which enters into the heating furnace. Film method oxygen-enrichment technology is applied to the heating furnace of the oil field, thereby reducing the excess air coefficient of the heating furnace, improving heat efficiency of equipment and saving energy.
Description
Technical field:
The utility model belongs to the special-purpose firing equipment matching component in ground, oil field, be mainly used in oil field heating furnace oxygen-enriched combustion-supporting system, be specifically related to a kind of special nozzle that is used for carrying the oxygen-enriched air that has certain pressure head, it is added in oxygen enrichment in the place that needs most in the heating furnace fire tube, and do not change the structure of original heating furnace, to the performance and the more not influence of safety of heating furnace.
Background technology:
In the oil field, the fuel of heating furnace and other firing equipments is based on fuel gas, and small part is a fuel oil, no matter gaseous fuel or liquid fuel, and its needed oxygen that burns is all from atmosphere.In conventional oil field heating furnace, the course of work of air in heating furnace is: air is by air-introduced machine or be subjected to the fuel gas jet to enter the heating furnace burner hearth, is at first heated by the high-temperature flue gas of burner hearth inside; After reaching uniform temperature, airborne oxygen and the fuel generation chemical reaction that newly enters burner hearth, the chemical energy in the fuel discharges with the form of heat energy, generates combustion product simultaneously; The heat that burning discharges has not only heated combustion product but also heated airborne other non-combustible gas, forms high-temperature flue gas and is flowed out by furnace outlet; In dissimilar heating furnaces, the heat transferred heated medium, the flue gas that has changed heat enters atmosphere by chimney to high-temperature flue gas by different modes.In the above-mentioned course of work, temperature was an environment temperature when airborne non-combustible gas entered heating furnace, temperature is an exhaust gas temperature when leaving heating furnace, and temperature difference is at least more than 100 ℃ between the two, and this part energy loss is unavoidable to the oil field at the combustion apparatus of usefulness.
Summary of the invention:
With the low problem of thermal efficiency of heating furnace, the utility model is applied to oxygen-enriched combustion technology on the oil field heating furnace at existing oil field, provide a kind of with at the special-purpose oxygen enrichment nozzle of the oil field heating furnace that is being complementary with oil field heating furnace.
The special-purpose oxygen enrichment nozzle of oil field heating furnace of the present utility model is elongated tubular, is divided into straight length and Taper Pipe section, and the Taper Pipe section is dwindled the formation nozzle to outlet, and the end of straight length is along being inlet.
Another purpose of the utility model is to provide a kind of combination that the heating furnace fire tube of the special-purpose oxygen enrichment nozzle of above-mentioned oil field heating furnace is arranged.
The burner nozzle that this heating furnace fire tube comprises heating furnace fire pipe end face and is installed in heating furnace fire pipe end face center, a plurality of oxygen enrichment nozzles of uniform fixedly installing on heating furnace fire pipe end face, the outlet of oxygen enrichment nozzle is positioned at heating furnace fire pipe end face one side.
In this heating furnace fire tube, the oxygen enrichment nozzle can be 2, is laid on the heating furnace fire pipe end face for the center symmetry with the burner nozzle.
In this heating furnace fire tube, the straight length of oxygen enrichment nozzle connection one provides the pipeline of oxygen-enriched air.
Adopt above design, introduce oxygen-enriched air by the oxygen enrichment nozzle, can reduce the non-combustible gas amount that enters heating furnace, thermal efficiency of heating furnace is improved, the energy obtains saving; The design of oxygen enrichment nozzle Taper Pipe section outlet except having the injection function, also has special angle, makes oxygen-enriched air enter the heating furnace fire tube with certain speed and angle, not only plays combustion-supporting effect, has also elongated flame, slows down fire tube wall burnout failure and takes place.The utility model is applied to membrane oxygen enrichment technology on the oil field heating furnace, reduces the heating furnace coefficient of excess air, improves equipment thermal efficiency, thus energy savings.
Description of drawings:
Fig. 1 shows the special-purpose oxygen enrichment structure of nozzle of the utility model oil field heating furnace sketch;
Fig. 2 shows that the utility model combination has the heating furnace fire tube scheme of installation of oxygen enrichment nozzle.
The specific embodiment:
The special-purpose oxygen enrichment nozzle of the oil field heating furnace that the utility model provides, its structure is seen Fig. 1, be elongated tubular, be divided into straight length 11 and Taper Pipe section 12, Taper Pipe section 12 is dwindled the formation nozzle to outlet 2, the end of straight length 11 is along being inlet 1, the oxygen-enriched air that is produced by the oxygen enrichment generating means enters straight length 11 and Taper Pipe section 12 by inlet 1, variable cross-section by Taper Pipe section 12, oxygen-enriched air speed obtains increasing, under the guide functions of nozzle, the oxygen-enriched air after the acceleration is entered with in the fire tube of heating furnace by outlet 2 at a certain angle, participates in burning.
See Fig. 2, show the installation site of oxygen enrichment nozzle 3 on heating furnace, wherein, burner nozzle 4 is installed in the center of heating furnace fire pipe end face 5, a plurality of oxygen enrichment nozzles 3 (being shown as 2 as Fig. 2) symmetry fixedly is added in the position all around of end face 5 top nozzles 4, and the inlet of oxygen enrichment nozzle 3 connects oxygen-enriched air.
In the utility model, these oxygen enrichment nozzle 3 materials are the 310S high temperature resistant stainless steel, and it has high temperature resistant, corrosion-resistant and machinability and stronger characteristics such as mechanical strength.Other has now burner nozzle 4 and heating furnace all need not with structure and changes.
Nozzle also has special angle except having the injection function, make oxygen-enriched air enter the heating furnace fire tube with certain speed and angle, not only plays combustion-supporting effect, has also elongated flame, slows down fire tube wall burnout failure and takes place.
Through field trial at Daqing oil field oil recovery factory terminal, after adopting the utility model oxygen enrichment nozzle, test heating furnace fire tube wall is not seen obvious scaling loss, just the need repairing present situation of fire tube wall of the time more than a year of having changed in the past, obviously prolong the maintenance cycle of fire tube wall, improved furnace apparatus service life.Thermal testing is the result show, the film oxygen enriching combustion supporting technology has certain energy-saving effect, can reduce the heating furnace energy consumption, realizes economical operation, saves natural gas about 3.03%.
