Description

Burner adapted for many kinds of gas and liquid fuel

The utility model relates to burner or daily kitchen range, relates in particular to the burner that uses gaseous state and liquid fuel.

Use the burner of gaseous state and liquid fuel generally to be special use at present, especially to using liquid fuel, be so-called novel liquefied petroleum gas kitchen range or novel gasification stove etc., because the chemical analysis and the physical property difference of liquid fuel, though on the structural design of burner, have any different, but it is all reasonable inadequately, to make cause service life short beyond, also have incomplete combustion, fuel consumption is big, poor thermal efficiency, CO content in smoke is crossed problems such as height.Because the existence of the problems referred to above, the development and use of new forms of energy have been hindered and efficient power-saving is supporting applies.

The existing problem of the burner of above-mentioned burner and vaporization mechanism is that this mechanism itself is insurmountable, no matter this vaporization mechanism is incense coil formula piping installation or Clothoid type piping installation and through type piping installation, because of the fuel of its supply is heated by piping installation by the principle of fluid afterflow, because the import of this piping installation and whole pipe passage are same bore all to outlet, thereby the liquid fuel of this piping installation of flowing through all is to equate from import up to the flow and the flow velocity of outlet.This is to making flow through time of the thermal treatment zone of liquid fuel shorter, is unfavorable for the liquid fuel vaporization of being heated at short notice.In addition since this piping installation to be subjected to flow restriction and must to adopt the more tiny pipe of diameter be material, yet the device that more tiny pipe constitutes is located in the thermal treatment zone to making heating surface area less, be unfavorable for that fuel fully vaporizes, simultaneously also just caused fuel gas to force down, it is little to penetrate the suction amount, amount of air drawn is few, fuel gas (fuel) should lack the fully rational mixing of combustion-supporting gas (air) and cause fuel not burn fully completely, has caused problems such as producing the CO too high levels in poor thermal efficiency and the flue gas thus.In addition, the liquid fuel of piping installation in the long term lower pipeline of flame that the diameter of delivering liquid fuel is more tiny tied carbon at pipeline inner wall easily, causes pipe blocking, influences service life.

The purpose of this utility model provides the burner complete, safe in utilization, energy-efficient, the suitable pluralities of fuel (gas, liquid gas) of good economy performance energy that gasifies fully, burns exactly for overcoming the problems referred to above or shortcoming.

Comprise the burner platform according to burner of the present utility model, be positioned at one or more burners and auxiliary equipment thereof on this burner platform, described burner and vaporizer structure body, burner structure body has the ringwise fire hole of inside and outside two circles in the form of a ring, described vaporizer is to be positioned between the internal diameter of burner structure body to be surrounded by the ringwise fire hole of burner inner ring, has the hollow tubular member that the annular space of supplying with fuel was imported and exported and can be held to fuel, described vaporizer fuel outlet is communicated with through needle-valve and burner structure body, and described auxiliary equipment comprises air regulator and above-mentioned vaporizer fuel is imported and exported the piping installation that connects.

Below, by reference figure the utility model embodiment is described.

Fig. 1 is the vertical view that schematically illustrates the utility model embodiment burner general structure.

Among the figure, 12 is the burner platform, 7 for being positioned at the burner structure body on the left of the burner platform, this burner member 7 has ringwise outer ring fire hole 8 and inner ring fire hole 9,10 for be arranged between burner 7 internal diameters at the burner inner ring hollow tubular vaporizer that surrounds of fire hole ringwise, 11 add the preheat burner of heat vapourizer 10 when lighting a fire for the cooling attitude, 13 for supplying with the piping installation of fuel, the fuel inlet of one end and vaporizer 10 is connected, its other end and fuel reservoir (not shown) are connected, 5 is air regulator, 6 is the fuel nozzle ports of needle-valve, and 4 is the needle-valve body that is connected with the fuel outlet of vaporizer 10, and 3 is the functional unit of air regulator 5,2 is the gauge tap of needle-valve 4, and 1 is the electronic ignition button.

In addition, on the right side of burner platform 12 burner has been installed also.

Now the structure body characteristics of the utility model burner 7 and the design feature of vaporizer 10, the effect of air regulator 5 are described.

Have inside and outside two and enclose ringwise that burner 7 its inner ring fire holes 9 of fire hole surround the vaporizer 10 that is positioned between burner 7 internal diameters, the combustion flame of interior low circle fire hole 9 is at first to 10 heat effects of vaporizer, and flame rising simultaneously still plays the calorific value as this performance of burner.The effect of inner ring fire hole 9 has replaced TY---the inner burner member effect of I type, thus making TY---the structure collectivity of II type burner is simplified, and makes product cost reduce (design of the utility model burner has also obtained and trial-produceed successfully, and test burn is respond well).

For having fuel, the cingens hollow tubular structure of inner ring fire hole body imports and exports vaporizer 10 for being positioned between burner 7 internal diameters.Because spatial volume obviously increases in this annular; the flow velocity that makes fuel enter vaporizer 10 obviously slows down; make the fuel thermal treatment zone of flowing through; obtain heat time heating time prolonging; compare with incense coil formula pipeline; make as in the vaporizer 10 of heating surface area; outward; on; under heating surface area obviously increase; therefore evaporation conditions is obviously improved; because fuel is fully vaporized; the air pressure that produces is higher; thereby strengthened the suction amount of penetrating, also just be easy to sufficient suction as the air of combustion-supporting gas, thereby make gas fuel burning complete; be beneficial to and reach efficient; purpose of energy saving; when the thermal efficiency is obviously improved, the pernicious gas content in combustion product or the exhaust is obviously reduced, the favourable protection that reaches environment.

In addition,, can enter the air capacity of burner structure body, improve efficiency of combustion according to the quality adjustment of different fuel because the utility model burner is provided with air regulator 5 at the external diameter of needle-valve spout 6.

The utility model mainly is applicable to liquid fuel, but also can be applicable to fuel gas fully, also can be by vaporizer as preheating can further improve efficiency of combustion to gaseous fuel, therefore, the utility model structure also is suitable for the burner of pluralities of fuel (gaseous state, liquid state).

In addition, the utility model burner need utilize preheat burner 11 when cold conditions is lighted a fire, and lights to guarantee safety.
