Abstract

The utility model belongs to a gas and liquid burner which is composed of a fuel inlet tube, an igniting switch, a furnace end, a burner, a metal net, a support frame, etc. and is characterized in that the periphery of the burner is provided with a vaporizing ring with double deck channels, the lower channel of the vaporizing ring is a vaporizer, the upper channel of the vaporizing ring is a drying chamber, and holes are arranged between the upper and the lower channels for communication. When in burn, liquid fuel is vaporized in the vaporizer and then sent into the burner for burning through the drying chamber. The utility model has the advantages of favorable vaporizing effect, safety, on need of preheat and no carbon deposit and can use both gas fuel and liquid fuel.

Description

A kind of Gas and liquid burner

The utility model relates to a kind of Gas and liquid burner, particularly a kind of can using gases fuel, can use the stove and accessory of liquid fuel, devices such as water heater again.

Use the stove and accessory and the water heater of coal gas, liquefied petroleum gas at present, can not directly use liquid fuel, so people have designed some special-purpose liquid fuel ranges, because liquid fuel such as light oil, carbon five etc. need gasification ability normal combustion, so great majority all adopt and set up vapor lamp and force fuel gasification, enter burner and burner combustion again, common vapor lamp mainly contains following several form: (1) exposed installation gasification tubular type; (2) secretly set the gasification tubular type; (3) in the combusting device stove burner of existing burner, add vapor lamp or in burner, kitchen range, add vaporizer in the water heater.The weak point that the burner of these several forms exists is: one, all need the direct heating and gasifying pipe of naked light, wayward heating-up temperature makes the part reach fuel cracking or cracking temperature, coking carbon deposit in causing managing, stop up vapor lamp and nozzle, need irregularly to remove carbon deposit, heat loss is bigger.Two, in burner, kitchen range, add the weldering vaporizer in the water heater and all need existing burner is done bigger change, when temperature is low gasification relatively poor, it is dangerous big to drip raffinate, is difficult for promoting.Three, by manually inflating, forced fluid flow causes woven hose to work under elevated pressures by vapor lamp, and the big burst of liquid ejection in case joint comes off is extremely dangerous.Four, need enough preheating time, just can enter the normal combustion state.

It is simpler that the purpose of this utility model provides a kind of structure, do not need preheating, and gasification result is good, energy-conservation, and temperature control is easy, and safe in utilization can use coal gas, liquefied petroleum gas, can use the Gas and liquid burner of liquid fuel again.

The utility model is realized in following mode: Gas and liquid burner comprises fuel inlet tube, ignitor switch, burner, burner, support, parts such as wire netting, be characterized in around burner, being provided with a gasification circle that double-deck passage is arranged, the lower channel of gasification circle is a vaporizer, upper channel is a hothouse, interchannel is porose up and down communicates, lower channel is established an inlet, join with steel cylinder, upper channel is established a gas outlet, and ignitor switch is received in this gas outlet, ignitor switch connects burner and burner, the burner top is equipped with wire netting, and gasification circle passage can adopt dull and stereotyped passage, and separate with dividing plate the centre, also can adopt helical duct, to strengthen heat-transfer effect.

Because the technical characterictic of this Gas and liquid burner is around burner a gasification circle that double-deck passage is arranged to be set, and can be suitable for so make improvements slightly on existing gas furnace and water heater.

The utility model has the advantages that: 1. it does not change the air feed or the liquid-supplying system of fuel tank, do not change ignitor switch, burner, the burner of existing stove and accessory and water heater yet, structures such as boiler face, just set up a gasification circle, the UTILIZATION OF VESIDUAL HEAT IN that is lost to the hot flue gas in the ambient atmosphere heated liquid fuel that gets up, make it gasification, but do not reach cracking or cracking temperature, fundamentally solved the coking carbon-collecting problem of the heating tube of some stove and accessory design.2. gasification is enclosed because suitable heat transfer area and buffering volume are arranged, and how much fuel burner needs what just gasify, and excess liquid can also be returned steel cylinder automatically, and it is very stable to burn.3. do not need preheating, open and start ignitor switch behind the steel cylinder valve and promptly catch fire, enter the normal combustion state immediately.4. wide accommodation can burn smart carbon five, can burn thick carbon five fuel again, can also burn light Fuel, methyl alcohol and coal gas, oil gas, not electricity consumption of use without air pump, does not need manually to inflate yet, no raffinate flows out, and no matter is cooking stove, or water heater, uses all fool proof.

The enforcement structure of the utility model stove and accessory is described below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of stove and accessory;

Fig. 2 is the cutaway view of gasification circle;

See among the figure, stove and accessory has the support 2 that supports pot 1, burner 4, burner 5 and ignitor switch 9, in former place of establishing drip tray, promptly around burner 4, be provided with the gasification circle 3 of a double-layer plate passage, the lower channel of gasification circle 3 is a vaporizer 11, upper channel is a hothouse 12, vaporizer 11 is established an inlet 6, links to each other with steel cylinder 7, and hothouse 12 is established a gas outlet 8, receive the inlet of ignitor switch 9, ignitor switch 9 connects burner 5 and burner 4 again, is equipped with wire netting 14 on the burner 4, and a dividing plate 13 is arranged between last lower channel, have aperture 10 above, supplied gas enters hothouse 12.
