Description

A kind of gasification burner for improving combustible combustion efficiency

Technical field

The utility model is related to firing equipment technical field, more particularly to a kind of vapour for improving combustible combustion efficiency Change stove.

Background technology

Fire is essential in people's daily life, is primarily used to add hot water, cooking food, raises indoor temperature etc.. In prior art, city the inside adopts natural gas as fuel, and because rural area can gather materials on the spot, therefore rural area also has Sizable family uses firewood as fuel.

Nowadays, agricultural crop straw, the combustion technology of tree limb are developed, and occur in that in prior art following Combustion technology：Stalk and limb are first inserted in primary fuel thorax and is burnt, by the air inlet amount for controlling primary fuel thorax, made Contain a large amount of fuel gas in primary fuel thorax institute smoke discharging, above fuel gas is used to burn next time, so, due to can Combustion gas combustion produces less harmful substance, and this causes this combustion technology compared to traditional combustion system, not only with more The advantage of environmental protection, while can be by pipeline above fuel gas, to facilitate the position of arrangement hot spot.

With further enhancing for environmental consciousness, the stalk of gained during proportion of crop planting is made full use of, it is right to reduce The dependence of fossil fuel, is an important directions of existing firewood gasification burner development.

Utility model content

The utility model provides a kind of gasification burner for improving combustible combustion efficiency, compared to traditional gasification burner, this The inlet of utility model combustion air is easy to adjust, and so, can obtain optimal efficiency of combustion according to the characteristic of combustible.

A kind of gasification burner for improving combustible combustion efficiency that the utility model is provided is solved by following technical essential Certainly problem：A kind of gasification burner for improving combustible combustion efficiency, including for obtaining the first burner hearth of fuel gas and be used for Second burner hearth of gas fuel burning, is provided with the flue gas for fuel gas circulation between first burner hearth and the second burner hearth Pipe；

Also including flow divider, for being passed through the first airduct of air in the first burner hearth, for being passed through in the second burner hearth Second airduct of air, the flow divider includes the entrance of an entrance and two outlets, first airduct and the second airduct End is connected in the different outlet of flow divider.

Specifically, firewood anoxycausis in the first burner hearth, the flue gas with fuel gas of gained enters through fume pipe Enter in the second burner hearth, fuel gas is sprayed again by port, lights fuel gas at port, to obtain being available for heating Flame.

Above flow divider is used for the amount that distribution enters into combustion air in the first burner hearth and the second burner hearth, so, this vaporization Stove only needs a blower fan, i.e. blower fan to be arranged on the entrance of flow divider, can be achieved with controllable to the first burner hearth and the second burner hearth Flow combustion air is supplied.During the combustion-supporting air quantity supplied respectively into the first burner hearth and the second burner hearth more than changes, The situation of combustible anoxycausis, can obtain optimal firewood gasification efficiency in by changing the first burner hearth；By changing to the The amount of the combustion air supplied in two burner hearths, can match optimal according to the amount by fuel gas produced in the first burner hearth Combustion air supply or obtain specific flame forms, so, optimal burning effect can be obtained according to the characteristic of combustible Rate.

It is preferred that the flow divider is respectively exported using different valve element control flows, so that as needed, regulation enters into first The amount of combustion air in burner hearth and the second burner hearth.Such as the first airduct and the second airduct, two valve plates are respectively adopted to control Uninterrupted in two airducts, each valve plate is inserted respectively in the flowing space of the first airduct and the second airduct, is inserted according to control Enter depth, reach the purpose of control uninterrupted.

Further technical scheme is：

Firewood combustion case and it is easy to bavin ash to collect in for ease of controlling the first burner hearth, also including being arranged in the first burner hearth Grate, the grate is the platy structure for being provided with multiple through holes, and the through hole is through the upper and lower end of grate, stove The lower section of bridge also has the first grey chamber.The entrance of fume pipe and the outlet of the first airduct are preferably arranged to respectively positioned at grate Upper and lower end.

Position is easy to for bavin ash to remove the first grey chamber, and first for can removing from the first grey chamber is provided with the described first grey chamber Ash bucket.

The dust collected during for ease of collecting cyclone dust removal, also including the horn mouth being arranged in the second burner hearth, The horn mouth is located at the lower section of the fume pipe mouth of pipe in the second burner hearth, and horn mouth in Concentric Reducers shape, bell-mouthed big end It is above.The horn mouth plays dust and gathers effect.

To realize that dust is limited in FX, the lower section of the horn mouth small end also has the second grey chamber.

For ease of dust is removed into the second grey chamber, second for can removing from the second grey chamber is provided with the described second grey chamber Ash bucket.

As a kind of unitary design, also including the axial flow blower being arranged in shunting valve inlet.

Due to this gasification burner operationally, need in the first burner hearth to be a hot environment, to avoid because thermal stress mistake The service life of many this gasification burners of impact, first burner hearth includes tubular thorax body and is fixed on the thorax held with thorax Lid, the thorax lid is in ellipse end socket shape or hemispherical head shape.

To avoid thermal loss and obtaining in the first burner hearth hot environment, the outside of first burner hearth be also enclosed with every Thermosphere.

The utility model has the advantages that：
