Abstract
The utility model discloses a heavy oil burner, and relates to the technical field of boiler equipment manufacturing. The heavy oil burner comprises an air register, an oil tube and an oil nozzle. One end of the oil tube is communicated with an inner cavity of the air register and is connected with one end of the oil nozzle. The inner cavity of the air register is provided with a firing stabilizer, a primary air adjusting device and a secondary air adjusting 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 an existing fuel oil burner is poor in atomization effect, only light oil can be burnt, the price of high-quality fuel oil is constantly increased, and the production cost of enterprises is higher and higher.
Description
Technical field
The utility model 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 crude oil and extracts remaining mink cell focus after gasoline, diesel oil.Current oil burner is to 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.
Utility model content
The purpose of this utility model is to provide a kind of heavy oil burner, and it is poor that it can solve current oil burner atomizing effect, the light oil that can only burn, 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 address the above problem, the technical solution adopted in the utility model 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, wind adjusting device and secondary air regulation device; Described oil burner nozzle is middle hybrid Y type oil burner nozzle, at other high energy ignition unit and the torch oil gun of being provided with of this oil burner nozzle.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is the utility model:
1, the centre hybrid Y type oil burner nozzle adopting, 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.Fully burning need to approximately 12 cubic metres of air for per kilogram oil (consider the crushing of wind path and leak out and the factor such as the 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 having adopted two-stage sparking mode, and atomization quality is good, is fuel so burner of the present utility model can adopt heavy oil, and this has reduced the production cost of enterprise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Heavy oil burner shown in Fig. 1 and Fig. 2, air register 1 comprises 4, wind adjusting devices 3 of stabilizer and secondary air regulation device 5; Middle 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 from down 100 millimeters of the horizontal center lines of oil burner nozzle 2; High energy ignition unit 6 is located at from the horizontal center line of oil burner nozzle 2 down the extended lines of 50 degree, and at 70 millimeters of places of the horizontal center line 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 7 fuel nozzles 2 of torch oil gun; The required air that burns is sent in stove by air register 1; Air register 1 is divided into two parts by air and feeds in stove, and a part is entered in stove by the stabilizer 4 at burner nozzle place by center, i.e. wind of root; Another part air enters in stove by axial blade from surrounding.Center air produces and rotatablely moves after stabilizer 4, make air-flow center produce a recirculating zone, reach the effect of stable ignition, when operation, can regulate primary air flow by the adjusting knob that is arranged on a wind adjusting device 3 on panel, ensure that root wind ratio is 10% to 20%; Enter the Secondary Air in stove from surrounding, by the adjustable axial blade arranging, regulate secondary air regulation device 5, the eddy flow wind ratio of the direct current of adjustable second wind, plays the effect of the adjusted size of the shape to burner flame.
It is fuel that this burner can adopt heavy oil, design rating be 2000 kilograms per hour, flameholding, thermic load is moderate, temperature field in furnace is even.Except burner itself has regulating power, adopt the different burners quantity that puts into operation, can significantly 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.Light torch oil gun by high energy electric spark, then light main oil gun by torch oil gun; Safety while being conducive to light a fire and stable; 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 under gaseous state.Oil is in the time of 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 three processes of burning, and carries out simultaneously.Therefore, oil atomization effect directly affects the result of use of burner.Y type oil burner nozzle 2 loads that this burner adopts can be adjusted to 25%, in the time not controlling excess air coefficient, regulate than reaching 1:20.Its air consumption is little, and air consumption is about 2% left and right of amount of fuel; Oil, steam pressure is not high, and oil pressure is 0.7 to 2.1 MPa conventionally, and vapour pressure is about 1.0 MPas.And atomizing angle is with load variations, atomization quality is better, and mean oil droplet particle diameter is 50 microns.
