Description

Burner for liquid fuel stove (range)

This burner relates to a kind of vaporizing burner that is applicable to various liquid fuels.

At present, liquid fuel furnace (kitchen range) burner of the domestic use of China, for burning simultaneously, solution liquid gas adopt liquid vapour isolating construction, mode of heating to have nothing in common with each other, the employing generating tube that has is contained in the burner bottom, make a part of boil-off gas ejection burning heating generating tube with the burner boring method, the intensity that this will influence main flame descends hot benefit; The horizontal burner top that is contained in of the employing generating tube that has causes main firepower to be split and is to reduce the thermal efficiency by two halves; The employing center annular generating tube that has, vaporization effect is good inadequately, and fuel can not finely burn, and wastes energy; The burner center that has does not have the secondary air inlet hole, thereby CO content in smoke is too high.Chinese patent application numbers 85108197 discloses a kind of vaporizing burner for liquid fuel, it is heated by heating wire, make fuel oil centrifugal spray, gasification by the motor rotation, deliver to the burner body ignition by air blast again, this type of burner structure complexity, cost an arm and a leg, volume is big, obviously is difficult to apply.Chinese patent application numbers 91106743.4 discloses a kind of burner with secondary vaporization of liquid fuel.It uses vaporization core and vaporization coil pipe secondary vaporizing, complex structure, and processing is difficulty relatively, makes troubles to manufacturing.

The purpose of this burner research provide a kind of simple in structure, easy to process, preheating time short, can cold ignition and thermal ignition and easy to use, reliable burner.

The task of this burner is achieved in that to be equipped with on burner body top and presses cover and go out compression ring.Interior cover is installed in the burner body inboard, is supported in the bottom of burner body.Support column and vaporization fire hole are arranged at interior cover bottom.The inboard emptying aperture place of cover in the vaporization coil pipe is contained in.The caliber of vaporization coil pipe bottom plate pipe is bigger than the caliber that other respectively encloses coil pipe.Vaporization coil pipe one end communicates with feed tube, and the other end is connected with escape pipe.The vaporization coil pipe is supported on the support column, and is fixed by screw.Send the preheating oil pipe to be fixed on the burner body bottom, send porosely on the preheating oil pipe tube wall to communicate with burner body bottom venthole.The vaporization coil pipe is the big down little truncated cone or cylindrical of.The diameter of vaporization coil pipe bottom plate pipe is (1.5～3) with diameter ratio that other respectively encloses coil pipe: 1.

This burner structure is simple, easy to process, owing to the vaporization coil pipe can utilize its underpart vaporization fire cmpletely it is heated evenly, and can shorten preheating time, and vaporization is complete, and energy cold ignition and thermal ignition are easy to use, reliable.

Fig. 1, this burner structure schematic diagram.

Below in conjunction with accompanying drawing this burner is described in further detail: interior cover (5) is housed in the burner body (1), and interior cover (5) is bearing on burner body (1) bottom, and support column (6) and vaporization fire hole b are arranged at interior cover (5) bottom.Go out compression ring (3) lower end and be bearing in interior cover (5) upper end, go out compression ring (3) upper end by pressing cover (2) to be fitted on the burner body (1), vaporization coil pipe (7) is that 8 millimeters bottom coils and a few loop diameter are that 4 millimeters coil pipes connections combine by a loop diameter, and its profile is the big down little truncated cone of.Vaporization coil pipe (7) is contained in the inboard through hole of interior cover (5) and goes out below the compression ring (3).Vaporization coil pipe (7) is supported on the support column (6) of interior cover (5), and fixing by the screw (4) of cover (5) in revolving.Feed tube (16) one ends are communicated with vaporization coil pipe (7) bottom coil pipe, and the other end is connected on the main control valve (15).Escape pipe (17) one ends are communicated with vaporization coil pipe (7) upper end small coils, and the other end is connected on the main control valve (15).It is fastening with screw (14) to send preheating oil pipe (10) to be through in the following hole of burner body (1), and an end is uncovered C, and on preheating dish (9), the other end and main control valve (15) interlink.Send last porose d of preheating oil pipe (10) and burner body (1) bottom venthole a to communicate.Nozzle (11) one ends are spun on the main control valve (15), and the other end is inserted in the burner body (1).Air door (12) and spring (13) are sleeved on the nozzle (11).Pulse firing pin (8) be fixed on burner body (1) below, the igniting pin over against the uncovered C that send preheating oil pipe (10).

During use, handle main control valve (15) pre-heating fuel by sending preheating oil pipe (10) in uncovered C place is input into preheating dish (9), pulse firing pin (8) discharges at uncovered C place simultaneously, pre-heating fuel is lighted, after 30～40 seconds of preheating, open main control valve (15), make liquid fuel enter vaporization coil pipe (7), liquid fuel is tentatively vaporized through vaporization coil pipe (7) bottom big coils earlier, the small coils that gas liquid mixture enters on the vaporization coil pipe (7) again continues vaporization fully, fuel gas after the vaporization enters in the nozzle (11) by main control valve (15) through escape pipe (16), after mixing, the air that nozzle (11) sprays also and air door (12) is located to introduce enters in the burner body (1), most of from going out hole, the slit discharge of giving vent to anger of compression ring (3), be preheated fiery ignition combustion, 8 the vaporization fire hole b ejection of another part below interior cover (5) is preheated fire equally and lights.The flame at vaporization fire hole b place is in order to keep the required heat of continuous vaporization of liquid fuel.

This burner also be provided with in use because of other reason flame-out in short-term after the device of igniting again.Its operation principle is: after flame-out in short-term, whole combustion system all is that heat is, just do not need to be preheated again the fuel preheating if continue to use, as long as handle main control valve (15), the fuel gas that enters in the burner body (1) just can be through the venthole a and the hole d of its underpart, uncovered C place through sending preheating oil pipe (10) discharges, lighted by pulse firing pin (8), fire is herein lighted the gas of discharging from vaporization fire hole b then, this fire is lighted again from going out the fuel gas that compression ring (3) is discharged, and finishes the process of thermal ignition.

This burner all is suitable for the various liquid fuel furnaces (kitchen range) of burning oils, alcohols, hydro carbons synthetic liquid fuel.
