Abstract
The utility model relates to a self-preheating oil burner. The front end of a barrel body is provided with an oil preheater, and the inner part of a barrel is provided with a compressed air nozzle which is sheathed on an oil nozzle. The compressed air can be formed the rotational flow which is forward by the compressed air nozzle, and flames can be sprayed into a furnace chamber by passing through a pre-oil device after the flames burn in the barrel. The utility model dispenses with an oil pump and can work as long as the oil can flow into the oil burner, and has the advantages of convenient operation and energy conservation. The self-preheating oil burner adopts the internal burning type and the small flame-spraying nozzle structure. The radiation heat for a spray head from the furnace chamber can be reduced, the self-preheating oil burner has good self-preservation function and long service life, and is suitable for various furnaces which burn the oil.
Description
The utility model belongs to a kind of burner of oil firing, and is particularly a kind of from the little oil mass oil firing of preheating device.
The little oil mass of industrial use is burnt to chew and is mainly used in ceramic tunnel (roller-way) kiln and is used for industries such as machinery smelting, lightization of building materials, and present chewing as burnings such as homemade Type B, F type and R types of generally using, it is big to exist oil consumption, and poor, defective such as igniting is difficult, coking is smoldered atomizes.
The purpose of this utility model provide a kind of can burn various fuel oils and the nozzle noncoking from the little oil mass oil firing of preheating device.
The utility model is finished with following mode, from the little oil mass oil firing of preheating device, it comprises oil pipe and fuel injection nozzle, front end at cylindrical shell is equipped with oil preheater, and fuel injection nozzle is housed in cylindrical shell, connects oil preheater through oil pipe, compressed air hose is sleeved on the oil pipe that connects fuel injection nozzle, the air nozzle of compressed air hose front end is sleeved on the fuel injection nozzle, and air nozzle is to be made of the inclined hole that has forward on the nozzle core, and oil inlet pipe connects oil preheater.Tail end at cylindrical shell is equipped with end plate; Cylindrical shell is double-deck, has pore on end plate and cylindrical shell, and oil pipe and oil inlet pipe are clipped between the bilayer of cylindrical shell.Inclined hole on the nozzle core has two or more.Opening taper wind gathering hoods backward is housed on air nozzle.Oil preheater is annular side's cover or ring pipe, and its front inner diameter is less than cylinder internal diameter.
The utility model is owing to adopt internal combustion type; compressed air produces high speed eddy flow forward before fuel injection nozzle, fuel oil is atomized better, fully mixes with air; reach completing combustion; flame is low-temperature space in tube, and the further burning in stove of flame ejection back produces the high-temperature region; help giving stove with the heat contribution of fuel; energy savings protects the fuel injection nozzle noncoking, increases the service life.

Below in conjunction with accompanying drawing the utility model is described in further detail:
In Fig. 1 and Fig. 2, form by oil preheater (1) double-layer barrel (2), fuel injection nozzle (5), air nozzle (4) and oil pipe (6) and oil inlet pipe (12), compressed air hose (3) from the little oil mass oil firing of preheating device.Front end at double-layer barrel (2) is equipped with tapered annular oil preheater (1), form the mouth that dwindles of a cylindrical shell (2), fuel injection nozzle (5) oil is housed after fuel injection nozzle (5) ejection in cylindrical shell (2), in the ring of oil preheater (1), pass and spray, connect oil preheater (1) and fuel injection nozzle (5) with oil pipe (6), oil inlet pipe (12) connects oil preheater (1), oil inlet pipe (12) and oil pipe (6) are installed between the double-layer barrel (2), fuel injection nozzle (5) is that a taper is chewed as shown in Figure 1, compressed air hose (3) is sleeved on the oil pipe (6) that connects fuel injection nozzle (5), front end at compressed air hose (3) is equipped with air nozzle (4), air nozzle (4) is made of nozzle core (7) and cap (13), nozzle core (7) is sleeved on the fuel injection nozzle (5), with cap (13) that nozzle core (7) is fixing, on nozzle core (7), have inclined hole (8) forward, as shown in Figure 3, after making the compressed air ejection, form the eddy flow that promotes forward, drive oil spout and promote to produce swirl flow combustion forward, inclined hole (8) can symmetry be opened two or more, at air nozzle (4) front end taper wind gathering hoods (11) is housed, in cylindrical shell (2), produce vacuum and compressed-air actuated jet action owing to burn, from the additional air that the hole (10) on the transom piece (9) of cylindrical shell (2) flows to, be convenient to combustion-supporting with wind gathering hoods (11) inspiration.The tail end of cylindrical shell (2) is equipped with end plate (9), on end plate (9) and cylindrical shell (2), have hole (10), on double-layer barrel (2), the tail end of outer layer barrel has the hole, the front end of internal layer cylinder has the hole, directly replenish flame mixing in the tube from this hole leaked-in air, form one time wind, the hole leaked-in air from the transom piece (9) of cylindrical shell (2) forms secondary wind.
Operation principle of the present utility model: oil preheater is to utilize advection heat and the radiant heat that jets out flames, and the radiant heat of accepting burner hearth (annular oil jacket is stretched in stove) makes the oil plant heat temperature raising, help the atomizing and the burning of fuel oil, this is very important for burning residual oil, heavy oil and coal tar, and is also beneficial to burning light oil.The mouth of annular oil preheater has reduced the radiant heat of burner hearth to shower nozzle, has played important function for reducing the spout coking.With oil atomization, gas makes the mist of oil rotation from tangentially spraying into to spray gun with compressed air (pressure is about 0.4MPa), and it is mixed to help oil gas, atomizing and vaporization.Utilize the effect of spraying suction and burning vacuum band.Suck air.Air is delivered to range of atomization and combustion zone in proportion according to the size and the distribution in hole.These air (containing compressed air) and fuel oil are cooling off the oil firing device again, play the self-shield effect.
Need not use oil pump from the little oil mass oil firing of preheating device, (fuel tank is higher than the oil firing device with regard to work as long as oil can flow into the oil firing device, residual oil will be heated to and can flow), during with ready-made oil pump, oil pressure is not higher than 0.05MPa, adopts low pressure oil, be in order to increase nozzle opening, make it be difficult for keeping operate as normal, also help simultaneously and make processing because of impurity stops up.From the little oil mass oil firing of preheating device is internal combustion type, and flame is low-temperature space in tube, and the further burning in stove of flame ejection back produces the high-temperature region.Tissue burning like this helps giving stove with the heat contribution of fuel.Spout is the depths in tube, except that reducing radiant heat, mainly is in order to finish mixing, atomizing, vaporization and ignition process in tube.
