Abstract
The invention discloses a heavy oil burner, relating to the field of boiler equipment manufacturing technology; the heavy oil burner comprises an air register, an oil pipe and an oil nozzle; one end of the oil pipe is communicated into the inner chamber of the air register and connected with one end of the oil nozzle; the inner chamber of the air register is provided with a steady burner, a primary air regulating device and a secondary air regulating device, and a high-energy ignition device and an ignition oil gun are arranged beside the oil nozzle. The heavy oil burner can solve the problems that a current fuel oil burner has a poor atomizing effect, and can only burn light oil, as the price of high-quality fuel oil rises constantly, the production cost of an enterprise becomes higher and higher.
Description
Technical field
The present invention relates to boiler plant manufacturing technology field, especially a kind of heavy oil burner for boiler.
Background technology
Boiler-burner is of paramount importance equipment in the complete auxiliaries of boiler, boiler-burner is mainly divided into oil burner, gas burner and dual fuel burner (also claiming oil-gas two-way burner), wherein oil burner can be divided into bumer of light fuel and heavy oil burner, light oil mainly refers to diesel oil, and heavy oil refers to the mink cell focus be left after crude oil extracts gasoline, diesel oil.Current oil burner is adopt one-level igniter mostly, and the atomizing effect of its oil burner nozzle is poor, so the light oil that can only burn; In recent years, along with the price of high-quality fuel oil rises steadily, make the production cost of enterprise more and more higher.
Summary of the invention
The object of this invention is to provide a kind of heavy oil burner, it is poor that it can solve current oil burner atomizing effect, and can only burn light oil, and the price of high-quality fuel oil rises steadily, the problem that the production cost of enterprise is more and more higher.
In order to solve the problem, the technical solution used in the present invention is: this heavy oil burner, comprises air register, oil pipe and oil burner nozzle; Described oil pipe one end passes into described air register inner chamber and is connected with described oil burner nozzle one end; The inner chamber of described air register is provided with stabilizer, First air adjusting device and secondary air regulation device; Described oil burner nozzle is intermediary hybrid Y type oil burner nozzle, and this oil burner nozzle side is provided with high energy ignition unit and torch oil gun.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention:
1, the intermediary hybrid Y type oil burner nozzle adopted, its input pressure is generally 0.7 to 2.1 MPa, and vapour pressure is about 1.0 MPas, and the distributive value in running regulates by changing input pressure, and the peak load of this nozzle regulates than being 1:10.Per kilogram oil Thorough combustion needs about 12 cubic metres of air (consider the crushing of wind path and leak out and the factor such as raising of oil inflame rate), and blast is 2.0 kPas.Atomizing angle is not with load variations, so atomization quality is good;
2, owing to have employed two-stage sparking mode, and atomization quality is good, so burner of the present invention can adopt heavy oil to be fuel, this makes the production cost of enterprise reduce.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Heavy oil burner shown in Fig. 1 and Fig. 2, air register 1 comprises stabilizer 4, First air adjusting device 3 and secondary air regulation device 5; Intermediary hybrid Y type oil burner nozzle 2, high energy ignition unit 6 and torch oil gun 7 are arranged on air register 1 inner chamber; One end of oil pipe 8 passes into the inner chamber of air register 1 and is connected with one end of oil burner nozzle 2; Torch oil gun 7 is located on the vertical center line of oil burner nozzle 2, and its position is the horizontal center line down 100 millimeters from oil burner nozzle 2; High energy ignition unit 6 is located at from the horizontal center line of the oil burner nozzle 2 down extended line of 50 degree, and at the horizontal center line 70 millimeters place apart from oil burner nozzle 2.
This burner adopts two-stage igniting, lights torch oil gun 7 by high energy ignition unit 6, then by torch oil gun 7 fuel nozzles 2; Air needed for burning is sent in stove by air register 1; Air is divided into two parts to feed in stove by air register 1, and a part enters in stove by center by the stabilizer 4 of burner nozzle, i.e. root First air; Another part air is then entered in stove from surrounding by axial blade.Center air produces rotary motion after stabilizer 4, air-flow center is made to produce a recirculating zone, reach the effect of stable ignition, the adjusting knob by being arranged on the First air adjusting device 3 on panel during operation regulates primary air flow, ensures that root wind ratio is 10% to 20%; Enter the Secondary Air in stove from surrounding, by the adjustable axial blade arranged, regulate secondary air regulation device 5, the Whirl deposite tank ratio of the direct current of adjustable second wind, plays the effect of the size adjusting of the shape to burner flame.
This burner can adopt heavy oil to be fuel, design rating be 2000 kilograms per hour, flameholding, thermic load is moderate, and temperature field in furnace is even.Except burner itself has except regulating power, adopt different burners to put into operation quantity, significantly can regulate boiler load, and furnace flame degree of filling is good.
This burner adopts two-stage igniting, and main oil gun adopts steam atomization mode.By high energy spark ignition torch oil gun, then light main oil gun by torch oil gun; Be conducive to safety when lighting a fire and stablize; Burning torch is equipped with electricpropulsion installation, so that realize program control.
Oil is a kind of liquid fuel, and the boiling point of liquid fuel is always lower than its ignition temperature, and therefore, the burning of oil is actually to be carried out in the gaseous state.Oil is when burning, and what directly participate in burning is not the oil of liquid condition, but " oil gas ".So the burning of oil comprises evaporation, diffusion and burning three processes, and carry out simultaneously.Therefore, oil atomization effect directly affects the result of use of burner.Y type oil burner nozzle 2 load that this burner adopts can be adjusted to 25%, regulates than reaching 1:20 when not controlling excess air coefficient.Its air consumption is little, and air consumption is about about 2% of amount of fuel; Oil, steam pressure are not high, and usual oil pressure is 0.7 to 2.1 MPa, and vapour pressure is about 1.0 MPas.And atomizing angle is not with load variations, atomization quality is better, and mean oil droplet particle diameter is 50 microns.
