Description

A kind of firewood combustion furnace

Technical field

This utility model is related to firing equipment technical field, more particularly to a kind of firewood combustion furnace.

Background technology

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

Nowadays, agricultural crop straw, the combustion technology of tree limb are developed, and occur in that following in prior art Combustion technology：Straw and branch are first inserted in primary fuel thorax and is burnt, by controlling the air inlet amount of primary fuel thorax, made Contain a large amount of fuel gas in primary fuel thorax institute smoke discharging, above fuel gas is used for burning 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 straw of gained during proportion of crop planting is made full use of, it is right to reduce The dependency of Fossil fuel, is important directions of existing firewood combustion furnace development.

Utility model content

This utility model provides a kind of firewood combustion furnace, and principle of the combustion furnace using gasification burner, compared to traditional vapour Change stove, in final the discharged flue gas of this utility model, dust content is lower, therefore this combustion furnace has more environmentally friendly advantage.

A kind of firewood combustion furnace that this utility model is provided is by following technical essential come solve problem：A kind of firewood burning Stove, including for obtaining first burner hearth and the second burner hearth for gas fuel burning of fuel gas, first burner hearth with The fume pipe for fuel gas circulation is provided between second burner hearth, and second burner hearth offers the drum of port in top Shape structure, the fume pipe are connected with the wall of the second burner hearth, and the mouth of pipe direction of fume pipe and the mouth of pipe in the second burner hearth Locate the tangential direction of the second burner hearth altogether to；

Also include flow divider, the first airduct for being passed through air in the first burner hearth, for being passed through in the second burner hearth Second airduct of air, the flow divider include 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 are entered through fume pipe Enter in the second burner hearth, fuel gas is sprayed by port again, at port is lighted fuel gas, to obtain being available for heating Flame.

In above structure, in the second burner hearth, the mouth of pipe of fume pipe is the outlet of fume pipe, by exporting court to fume pipe To the restriction with the second burner hearth shape, after flue gas produced by the first burner hearth is sprayed in the second burner hearth, flue gas is along the second burner hearth Wall helical form rise at port, i.e., now, there occurs in the second burner hearth equivalent to flue gas produced by the first burner hearth Cyclone dust removal, so, effectively can reduce flowing at port the amount of particles contained shape impurity in flue gas, and so, this combustion furnace is fired The dust for burning gained is less.

Above flow divider for distribution enter into the first burner hearth and the second burner hearth in combustion air amount, so, this burning 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.

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.

Further technical scheme is：

For ease of controlling in the first burner hearth firewood combustion case and being easy to bavin ash to collect, 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 is also with the first grey chamber.The outlet of entrance and the first airduct of fume pipe is preferably arranged to respectively positioned at grate Upper and lower end.

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

For ease of the dust collected during collecting cyclone dust removal, also including the horn mouth being arranged in the second furnace chamber, 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.

For realizing dust is limited in fixed area, the lower section of the horn mouth small end is also with the second grey chamber.

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

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

Due to this combustion furnace operationally, need in the first burner hearth to be a hot environment, for avoiding because thermal stress mistake The service life of many this combustion furnaces of impact, first burner hearth include tubular thorax body and are fixed on the thorax held with thorax Lid, the thorax lid are in ellipse end socket shape or hemispherical head shape.

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

This utility model has the advantages that：
