Description
Technical field
The invention belongs to burner, especially belong to the liquid fuel gasification furnace head.
Background technology
Shortcomings such as gaseous fuel exists volume big, and is in light weight, and transportation needs pressurization, higher than liquid fuel cost of transportation, and danger is big, the price of liquefied gas is constantly soaring.At present, chemical fuels such as existing ripe alcohol radical liquid fuel replacement liquid gasification, gasoline, diesel oil.Alcohol radical liquid fuel burning back cleaning, environmental protection, but because the calorific value of liquid fuel is low, need usually could improve fuel value with burning behind its pressurization, the heating and gasifying, so burning initially makes it to be gasificated as the key of various burners to liquid fuel heat.Through retrieval its heater of ZL201110004602.0 " alcohol radical liquid fuel electronics gasification kitchen range " being arranged is the electrical heating outside gasification tunnel of spiraling; Leaning on the air in the electric heater unit heating cover body is that medium comes the heating and gasifying passage; Heat time heating time is long; Initial combustion speed is slow, and controlled pressure is not easy.ZL200820129334.9 < methanol liquid fuel gasifying stove>in order to solve the thermal source of initial gasification, is provided with oil groove in burner, earlier to the oil groove oiling, after the ignition, burner is heated up during use.The cover body of present various burners is a hollow-core construction, the heat accumulation weak effect, and often leakage of oil, breaking out of fire easily, a period of time after the heater stop heating, the temperature of cover body descends gradually, reheats again, can't use uninterruptedly.
Summary of the invention
The objective of the invention is to overcome the shortcoming that the aforesaid liquid fuel burner exists, provide a kind of to liquid fuel directly heat, the fireballing liquid fuel gasification furnace head of initial combustion.
The technical scheme that the present invention adopted is a kind of liquid fuel gasification furnace head, and it comprises nozzle, igniter, body of heater, hovers above gasification tunnel, base, heater in the body of heater, and base is positioned at the below of body of heater; Nozzle, igniter are fixed on the base; Body of heater is fixed in burner hearth through journal stirrup, and nozzle places the body of heater center, and nozzle comprises trunk line that is connected with gasification tunnel and the subtube that joins with trunk line; Have spout on the subtube; Igniter is positioned at the spout top of nozzle, and its main points are that heater is an electric heating tube, and electric heating tube is fixed in the gasification tunnel inner chamber.
Have 1-3 spout on each subtube at interval, the aperture of spout increases from inside to outside gradually.
The present invention improves on the basis of existing burner; Electric heating tube is fixed in the gasification tunnel inner chamber; Liquid fuel flows between the inwall of electric heating tube and gasification tunnel, and flow of liquid is crossed electric heating tube and directly obtained heat, changes existing indirect into direct heating; Accelerate initial combustion speed, shortened the start-up time of whole combustion system.
Body of heater is solid torus, gasification tunnel and body of heater cast solid.Because body of heater is solid torus, the heat that from burned flame, is absorbed is many, and heat accumulation is many, and enough heats can be provided for follow-up fuel gasification, thereby has guaranteed the sustainability of normal combustion.
Body of heater is that cast aluminium is processed, and its inwall has protective sleeve, and there is the convex edge top of protective sleeve, and base is fixedly connected with protective sleeve.
In order to prolong the service life of body of heater, prevent that body of heater is impaired in fuel combustion process, wall increases the protective sleeve that stainless steel material is processed within it, and convex edge and protective sleeve are fixedly linked, and are positioned at the body of heater top, play the effect of supported weight.
The control circuit of electric heating tube is a timing means; According to the gasification point of different fuel and the power of electric heating tube, crossing with fluidized flow that electric heating tube can all gasify is foundation, will be controlled at 10-300 second the time for well; And be arranged to several gears; Usually with the 2-3 shelves for well, supply to select under the varying environment temperature to use, environment temperature is short high preheating time.Simple in structure, long service life.
Electric heating tube also can be controlled by attemperating unit, and attemperating unit mainly comprises temperature controller, auxiliary reclay or contactor, hot wire.Burner links to each other with temperature controller through hot wire, when the burner heating-up temperature reaches the temperature controller setting value, then cuts off the heating tube circuit automatically; When end flue temperature was lower than the temperature controller setting value, then heater circuit was connected the heating burner, guaranteed the not gasification temperature of low fuel of end flue temperature.If burner is not worked, powered-down switch then.
The central plane of subtube is parallel with horizontal plane, has 3-12 central angle such as subtube evenly to distribute.
6 subtubes are arranged, and the aperture of spout is 0.7-1.5mm, and the optimum aperture is 1mm, and spout is opened the outer end at subtube, with the spacing t of inboard wall of furnace body be the 1/6-2/5 of inboard wall of furnace body radius r, the angle of spout and horizontal plane is 45 degree ± 2 degree.The flame of 6 spouts just becomes a circle, and rotation is risen, sufficient combustion.
The subtube center is a circular hole, and outer cross section is an equilateral hexagon, and trunk line is vertical with subtube, and the rib of subtube is parallel with horizontal plane, and spout is on the side of rib, and 6 spouts are in the same side.Selecting outer cross section is that the subtube of equilateral hexagon is convenient in order to process the location.
The invention has the advantages that the indirect gasification with traditional liquid fuel changes direct heating into,, accelerate initial combustion speed, shortened the start-up time of whole combustion system the directly fixing gasification channel lumen of electric heating tube.Simultaneously body of heater is processed solid torus, heat accumulation is many, and the heat that from burned flame, is absorbed is many, and enough heats can be provided for follow-up fuel gasification, thereby has guaranteed the sustainability of normal combustion.Position and size through testing preferred spout make flame plate screw on liter, sufficient combustion, and the thermal efficiency is high.
