Technical field
The invention belongs to stove technical fields.It can be improved biomass fuel benefit in burning in particular it relates to one kind
With the furnace core of efficiency.
Background technique
Biomass fuel refers to biological material burning that as fuel, generally mainly agriculture and forestry organic waste material (saw by such as stalk
End, bagasse, rice chaff etc.).In some long-term lower areas of temperature on average, the especially some high altitude localities in Tibet, agriculture and animal husbandry
Daily necessities will burn a large amount of biomass fuels for daily heating or heating food.But extremely frigid zones vegetation is more sparse, fuel
Also more rare, peasants and herdsmen usually use cow dung dried etc. as fuel.However, in the case where fuel is more rare, it is existing
Stove it is still more rough in the use to fuel, using it is any improve fuel availability structure or device, make
It is relatively low to the utilization efficiency of biomass fuel to obtain existing stove.
Summary of the invention
It is an object of the invention to：There is a problem of for existing stove lower to the utilization efficiency of biomass fuel, mentions

Axis intersects with the axis of cylindrical portion.More oxygen contents are provided, keep burning more abundant.This programme oxygen is provided directly to fire
The flame core of flame, more conducively burning are abundant.
Preferably, there are two outside air inlet is arranged in the opposite two sides of annulus.Outside air inlet is arranged in
Opposite sides keeps oxygen entrance more abundant.
It preferably, further include air inlet pipe；One end of air inlet pipe is connect with outside air inlet, and the other end extend out to furnace
Has bottom；Make to be connected to outside ring chamber and stove.Stove external oxygen is introduced by air inlet pipe, is capable of providing more oxygen
Gas.Stove bottom oxygen content etc. is big, and more oxygen is made to provide burning.
Preferably, it is provided with fire grate component below furnace core seat, fire grate component includes fire grate ontology and bracket；Bracket
It is securely fitted on stove, fire grate ontology can be assemblied on bracket with the relative rotation, and fire grate bodies top is provided with nose bar, be led to
Rotary fire grate ontology is crossed, the lime-ash of nose bar agitation agglomeration is made, and then lime-ash is made to scatter, is finally fallen.Nose bar is provided at least two
It is a；Fire grate ontology is circle, and nose bar is arranged in a circular formation on fire grate ontology, and the center of circle and fire grate ontology that nose bar is rounded
The center of circle is overlapped；Nose bar has been arranged in a circular formation at least two circles on fire grate ontology；Each circle nose bar is arranged interlacedly.It is more conducive to stir
It is dynamic or stir lime-ash, so that lime-ash is easier to be stirred and is fallen.
Preferably, fire grate ontology is circle, and fire grate body central is provided with axis hole；Protruding shaft is provided on bracket,
Protruding shaft, which is assemblied in axis hole, rotate fire grate ontology can relative to bracket；The both ends of bracket are provided with the company for being assemblied on stove
Hole is connect, the bracket between two connecting holes is in U-shape, and the depth of U-shaped is greater than the thickness of fire grate ontology；It is provided on bracket for branch
The boss of fire grate ontology is supportted, protruding shaft is arranged on boss；Axis hole and the axis of protruding shaft are overlapped with the axis of furnace core shell.This programme mentions
For a kind of rotational structure, structure is simply firm.When fire grate ontology is assemblied on stove, U-shaped is unlikely to make fire grate ontology and furnace
Tool interferes, and influences to rotate.Boss and fire grate contact area are smaller, reduce friction, and the more conducively rotation of fire grate ontology is more sharp
In agitation lime-ash.
Preferably, further include drive rod for driving fire grate ontology to rotate, drive rod is L-shape；Fire grate ontology
On be provided with drive hole, drive rod one end is removably attached in drive hole.Fire grate body temperature is high, and this programme provides one
Kind drives mode of walking around.
Preferably, furnace core shell and furnace core seat, combustion-supporting and combustion-supporting lid, fire grate ontology and bracket use cast iron material
Material.Cast iron materials high temperature resistant.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the invention are as follows：It is logical
It crosses feed inlet and places fuel.Ring chamber is steady air current room, provides source of oxygen by outside air inlet, then pass through inside air inlet
More oxygen is provided for flame, and then realizes the effect or effect for promoting flame combustion.When fuel combustion is insufficient, have
The gases such as carbon monoxide can further improve burning by providing the unburned abundant gas being mingled in more oxygen more flames
Efficiency.By furnace core assembly on stove, heat caused by the biomass fuel of burning Unit Weight can be improved.
