Abstract

The utility model relates to a high efficient energy saving gas burning device, composed of metal mesh infrared radiator and low-voltage injection burner integrally for middle gas stove and big stove. The device is composed of an inner ring and an outer ring. The outer ring is adopted with a metal mesh infrared radiator, and the inner ring is adopted with a low-voltage injection. Burner the burning head of the inner ring is in a radiate shape, and a plurality of gas passages, a major eductor and an associate eductor are arranged around a central protruding shape fire hole along radial direction uniformly. Thus heat efficiency is high, and fuel gas sources such as natural gas, manufactured gas and liquefied petroleum gas can be used.

Description

High efficient energy saving gas burning device

The utility model relates to the burner in combustion gas Chinese meal stove, the large stove, is by combustion gas wire netting infrared radiator and combustion gas low-pressure injection formula sets of burners all-in-one-piece burner, can use fuel gas sources such as natural gas, artificial coal gas, liquefied petroleum gas.

At present, the burner of general combustion gas Chinese meal stove, large stove mainly is made up of the low-pressure injection formula burner of different types.This burner combustion flame is long, needs the combustion space big.But the heating surface area of cookers such as China's Chinese meal stove and large stove is little, both are incompatible, thereby burned flame generally all surpasses the upper end that is heated cooker, cause the waste (thermal efficiency of GB regulation cooker is (30～40%)) of (60～70%) combustion gas, make smoke evacuation system overheated simultaneously, bring difficulty and inconvenience for the cooker design and use.

For overcoming the shortcoming of existing gas combustion apparatus, the purpose of this utility model provides a kind of with wire netting infrared radiator and low-pressure injection formula sets of burners all-in-one-piece efficient energy-saving gas burner, thermal efficiency height not only, and be applicable to different size model, the heating of cookers such as the Chinese meal stove of different capacity, large stove.

The purpose of this utility model is realized by following technical proposals.

Burner is made up of inside and outside circle, and the wire netting infrared radiator is adopted in the outer ring, to make full use of aphlogistic radiant heat; Inner ring adopts low-pressure injection formula burner, to make full use of the advection heat of flame and high-temperature flue gas.The design position, middle and lower part that combustion flame is controlled at be heated cooker like this helps improving total effect of the thermal efficiency.

I-I among Fig. 3, Fig. 2 is to cutaway view

Now the utility model is described in further detail in conjunction with the accompanying drawings.

As shown in Figure 1: the outer ring of burner is the wire netting infrared radiator, and it is made up of parts such as outer net 1, hold-down screw 2, last press box 3, following press box 4, Intranet 5, head shell 6, secondary injector 9b; Inner ring is a low-pressure injection formula burner, and it is by combustion head 7, and parts such as main injector 9a are formed.

As shown in Figure 2: the combustion head 7 of inner ring is radiation, promptly round central boss shape fire hole 8 be the radiation direction uniform some air flues 13, every air flue upper wall uniform again several boss shape fire holes 8, so be called the radial pattern combustion head, the combustion head of the fire hole that distributes with common annular is compared and is had the following advantages, and 1, the required auxiliary air supply condition of fuel gas buring is better; 2, firepower is more concentrated; 3, the design of center fire hole can make at the bottom of the direct heating kettle of flame, and this raising to the thermal efficiency has great role.

The cutaway view of the boss shape fire hole 8 on center fire hole and each air flue is as shown in Figure 3: the end face of fire hole be very little anchor ring, and its optimum size is d+(1-2) mm, purpose is the raising tempering limit, and is very favourable to preventing tempering.The side of boss is a taper seat, the angle α of side and end face: 90 °＞α＞50 °, purpose is to guarantee that the auxiliary air supply condition is good.

As shown in Figure 1: the outer net 1 of outer ring is made up of two-layer iron-chromium-aluminum metal net, and combustion gas and air are blended in the burning of this net surface, is heated up in its surface to reach (850～900) ℃, by the heat radiation mode, heat transferred is heated cooker.Intranet 5 is an individual layer iron-chromium-aluminum metal net, and purpose is to prevent tempering.Outward, Intranet (1,15) optimum size specification is respectively (4～10) order/inch and 44 order/inches.Outward, interior wire netting fixes with head shell 6 by hold-down screw 2, last press box 3, following press box 4.Interior wire netting and the horizontal plane certain angle that need tilt outward.Purpose is the position, middle and lower part that thermal-radiating direction is concentrated on be heated cooker.

Major and minor injector (9a, 9b) version is identical, by compositions such as injection pipeline 14, air regulating board 10, nozzle 11, hold-down nuts 12.The pipeline head of injector adopts thread connecting mode, and respectively with combustion head 7 and housing 6 bottom connections (as shown in Figure 1, 2), combustion gas is supplied gas to combustion head 7, wire netting (1,5) respectively through nozzle 11, pipeline 14.Be threaded and dwindled the connection area, created condition for adopting emanant head construction.Hold-down nut 12 plays fixing and regulates the effect that nozzle 11 is in the optimum position, rotates the size that air regulating board 10 can be controlled air inflow.

The Load Distribution ratio of the inside and outside circle of this burner is 6:5 or 5:5, and it is to realize by the air inflow of regulating major and minor injector.

The utility model can reach more than 50% the thermal efficiency of gas range for cooking Chinese food and large stove, improves more than 20% than GB, also improves more than 10% than existing domestic advanced product.
