Description

Kitchen range burner using liquid fuel

The utility model relates to a kind of combustion furnace burner, particularly a kind of burner of range for liquid fuel.

It much is to adopt coiled that the vapourizing unit of present liquid fuel burner has, and burns because the vaporization fire directly faces toward coil pipe, makes the coil temperature height, and its internal resistance is big, under the bad situation of fuel, be easy to generate clogging, this just makes cooking stove poor for applicability to fuel.Chinese patent application numbers 91106743 discloses a kind of liquid fuel secondary vaporizing burner, and vaporization fully, and is effective, but structure is complicated, the manufacturing cost height.Chinese patent application number 85108197 disclosed vaporizing burner for liquid fuel, it is heated by heating wire, makes the burner structure complexity by motor rotation, costs an arm and a leg, volume is big, obviously is difficult to promote the use of.A lot of burners all need pre-heating fuel when bringing into use, and the preheater heating surface is little when using in addition, makes preheating time long, and it is also incomplete to vaporize.

The purpose of this utility model provides that a kind of liquid fuel evaporation is effective, the thermal efficiency is high, simple in structure, use reliably, bring into use the liquid-fuel burner of the other preheating of Shi Buxu.

Task of the present utility model realizes with following mode: the vaporization core is housed in burner body, and fire lid is pressed between burner body and the vaporization core by gland, and the vaporization core connects feed tube and escape pipe are housed, and vaporization core center is an air hole into.The vaporization core is by air storage chamber, once gasify cavity and secondary vaporizing circle formed.Once gasify cavity respectively through being communicated with the secondary vaporizing circle be positioned at above it communicating pipe and being communicated with the air storing cavity that is positioned at the air storage chamber below it through the aperture of giving vent to anger, secondary vaporizing circle and once vaporize gapped between the cavity.Feed tube is communicated with the cavity that once gasifies, and escape pipe is communicated with the secondary vaporizing circle.Be filled with steel wire or copper mesh in the gasification cavity.The steel ball of diameter less than the endoporus aperture is housed in the hole of secondary vaporizing circle.

The utlity model has simple in structure, easily manufactured, use reliable, bring into use characteristics such as the other preheating of Shi Buxu, liquid fuel evaporation are effective, thermal efficiency height, be particularly suitable for using the burner usefulness of liquid hydrocarbon fuel, also can be used for using the burner of alcohol liquid fuel to use.

Fig. 1 has the liquid fuel burner structural representation of air storage chamber and secondary vaporizing device.

Below in conjunction with accompanying drawing the utility model is described in further detail:

The chimb 14 of the air storage chamber 2 of vaporization core 12 is sleeved on the shoulder of burner body 1.Fire lid 9 one ends top is contained in the projection ditch 13 of secondary vaporizing circle 5, and the other end is press-fited the jet-burner that is fixed on burner body 1 by gland.Vaporization core 12 centers are through holes of air into.Vaporization core 12 is by air storage chamber 2, once vaporize cavity d and secondary vaporizing circle 5 formed.The cavity d that once gasifies is communicated with the secondary vaporizing circle 5 that is positioned at above it and is communicated with the air storing cavity a that is positioned at the air storage chamber 2 below it through the aperture b that gives vent to anger through tube connector 4 respectively.The secondary vaporizing circle 5 and the gapped c between the cavity d that once vaporizes.Feed tube 3 one ends are communicated with the cavity d that once vaporizes, and the other end is communicated with combustion fluid fuel case and omits in the accompanying drawing 1.Escape pipe 8 one ends are communicated with secondary vaporizing circle 5, and the other end connects control valve 11.Once vaporize and be filled with disorderly group of stainless steel wire in the cavity d.The steel ball 6 of an amount of diameter less than the endoporus aperture is housed in the hole of secondary vaporizing circle 5, and steel ball 6 quantity are decided on secondary vaporizing circle 5 girths of cooking stove, and arranging full steel ball or arrange full steel ball on interior hole length can not.The interior steel wire that loads of the cavity of once vaporizing is group disorderly, and purpose causes liquid fuel to increase the heat exchange heating surface (area) (HS herein for increase heat conductor area, helps liquid fuel and once vaporizes.Add an amount of steel ball 6 in secondary vaporizing circle 5 holes, one of purpose strengthens heat transfer area, helps the liquid fuel secondary vaporizing, and two of purpose is to help the more stable output of boil-off gas.Purpose three for rocking steel ball, can remove the obstruction of waste fuel to secondary vaporizing circle 5.

Use principle is: control valve 11 is closed before using, in once vaporize cavity d and air storing cavity a, owing to be pressed into liquid fuel from liquid fuel tank to the chamber of the cavity d that once gasifies, liquid fuel has combustible vapor to be stored in the air storing cavity a because of volatilizing naturally, and forms saturated vapor.After control valve 11 is opened, these steam enter control valve 11 in nozzle sprays into burner by escape pipe 8, and bring the air mixing into from air-vent and fire burns after fire covers 9 discharge points, the a small amount of combustible vapor fuel that comes out from slit C is also lighted simultaneously, to 5 heating of secondary vaporizing circle, all arranged until steam.Liquid fuel enters vaporization chamber d one time through feed tube 3, and its inner steel wire disorderly further heated liquid fuel of group makes its volatilization, can continue vaporization after the liquid fuel of vaporization is not heated as yet again keeping the flame normal combustion, thereby save this link of preheating.Because the b hole is less, liquid fuel is difficult for entering air storing cavity a, to guarantee not having liquid in it, even there is liquid fuel to enter, when the stove burning was used, the duration and degree of heating of whole burner body 1 partly also was heated, and the liquid fuel that enters air storing cavity a also can be heated vaporization and discharge.
