Abstract

The utility model provides a novel high-efficient burner and design scheme for a combustion gas (or vaporisation) cooking stove. The high-efficiency stepped internally-spraying swirling flame burner is characterized in that a multi-layer stepped structure is adopted. Flame sprays internally in a horizontal way and burn rotatablely to form multi-layer swirling flame which burn like tinder. The high-efficiency stepped internally-spraying swirling flame burner burns in an ideal state and has the highest efficiency, being a generation changing product which replaces present common burners.

Description

High-efficiency stepped internally-spraying swirling flame burner

This novel high efficiency combustion device, particularly multistage grid structure that relates to a kind of domestic gas (or vaporization) stove and accessory, the burner of the horizontal injection rotation of flame belongs to combustion gas tool process industry field.

Along with improving constantly of China's living standards of the people, people increase rapidly life fuel demand easy to use, clean hygiene, liquefied petroleum gas originally in short supply, coal gas etc., and the contradiction that supply falls short of demand now is more outstanding.How to make full use of existing valuable fuel source, had realistic meaning widely.

Make a general survey of panoramic on the market various furnace combustors, its fire hole is nothing more than being two kinds of forms: the one, directly upwards; The 2nd, incline material upwards.The combustion system of these two kinds of form fire holes all belongs to disposable burning, if primary combustion is incomplete, remaining combustion gas has been wasted with regard to running away in vain.Like this, both waste valuable fuel source, again air, environment had been caused pollution, but also increased user's fuel cost spending.Write according to Zhao Shibin, the technical data that " use of household gas apparatus and maintenance " book of being published by Guangdong science and technology publishing house provides learns that the thermal efficiency of disposable combustion system only about 55%, this shows that the efficient of ordinary burner is lower.

This novel purpose just is, to greatest extent combustion gas is fully burnt, and improves energy conversion efficiency, and combustion loss is reduced to minimum of a value.Based on this purpose, the present invention has adopted off the beaten track unique design scheme, has taked repeatedly the mode of burning repeatedly, makes it to reach the ideal burning state.

This novel concrete structure is seen the accompanying drawing diagram.

Fig. 1,2, the 3rd revolves the vertical view and the profile of flame burner according to the efficient ladder injection of this novel proposition.

Describe the concrete apparatus features and the working condition of this novel proposition of foundation in detail below in conjunction with accompanying drawing.

1, multi-step injection structure: burner is made up of loam cake ［ 1 ］ and lower cover ［ 2 ］, loam cake ［ 1 ］ comprises multi-step ［ 4 ］, ［ 5 ］, ［ 6 ］ (also can increase stratum according to actual needs), and every layer circular fire hole ［ 3 ］ is all towards burner center inner face.When the ventilation burning, combustion gas is led to fire hole ［ 3 ］ spray combustion inwardly through the channeling ［ 7 ］ between loam cake ［ 1 ］ and the lower cover ［ 2 ］, if lower floor ［ 4 ］ primary combustion is incomplete, is burnt once more by the column of flame of middle level ［ 5 ］ ejection again after heat rises; If upper strata ［ 6 ］ primary combustion is incomplete, will be burnt once more by the rising flame of following stratum ［ 4 ］, ［ 5 ］.

2, flame horizontally rotates structure: each fire hole ［ 3 ］ of every stratum intersects 40 °～70 ° angles ［ 8 ］ with central point ［ 9 ］ in the horizontal direction, and each fire hole is together towards a direction.Like this, when the ventilation burning, the column of flame of the column of flame of back fire hole ejection and the ejection of previous fire hole collides, carry out second-time burning, simultaneously,, formed flame and horizontally rotated eddy current in the same way under the thrust at each column of flame, under the effect of eddy current revolving force, do not have clean-burning residue combustion gas, do not stop repeatedly repeatedly rotary combustion rise rotary combustion once more again, at last, flame heat rises heated body is carried out heat transmission and the width of cloth is penetrated heat transfer.So far, can think that combustion gas very burnt up hill and dale.

3, this device again because of having produced the cause of bumpy flow in the level, makes its hot cohesion fine owing to adopt unique ladder injection structure.The heat energy that the burning back produces, less to burner peripheral space diffusion heat transfer, can rest on the long period in the inner space of burner, therefore, the more effective heat energy that makes fully conducts heat to heated body, thereby has improved the thermal efficiency greatly.

According to These characteristics as seen, as the heat loss of deaeration circulation, this novel efficiency of combustion should be 100%.Observe by material object Actual combustion on stove and accessory, proving effect is splendid, and this is that the burner of other version is incomparable.

This novel stove and accessory that not only is used for gaseous fuel (liquefied petroleum gas, coal gas etc.) can be used for the stove and accessory that liquid fuel (kerosene, novel synthetic fuel etc.) burns again equally after gasification.If apply, to environmental protection, energy savings reduces personnel expense money's spending, will produce obvious social.

Claims

1, a kind of high efficiency burnt gas (or vaporization) furnace combustor, the particularly burner of ladder inwall flame horizontal-jet inward turning.It is characterized in that:

A, multistage grid structure [4], [5], [6];

B, every rank vertical plane along continuous straight runs bore circular fire hole [3];

C, each fire hole of every stratum [3] intersect 40～70 ° of angles [8] with burner central point [9], and the direction unanimity.

2, burner according to claim 1 is characterized in that combustion gas passes through channeling ［ 7 ］, and from each fire hole ［ 3 ］ of each stratum, level is inwardly sprayed rotary combustion.
