Description
Technical field
The invention belongs to stove technical fields.It can be improved the utilization in burning of coal fuel in particular it relates to one kind
The furnace core of efficiency.
Background technique
Coal is one of indispensable energy source of human production life.Some long-term temperature on average lower ground
The some high altitude localities in area, especially Tibet, peasants and herdsmen need to burn a large amount of fuel for daily heating or heating food.But
It is that extremely frigid zones vegetation is more sparse, and biomass fuel is more rare, available biomass fuel is extremely limited.Peasants and herdsmen
Need to buy coal as fuel, this just adds additional the daily expenditure of peasants and herdsmen.However, the situation more rare in fuel
Under, existing stove is still more rough in the use to fuel, using it is any improve fuel availability structure or
Device, so that existing stove is relatively low to the utilization efficiency of coal fuel.
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 coal fuel, provides
A kind of furnace core improving coal utilizaton rate.After the furnace core is assembled on stove, the coal of burning Unit Weight can be improved
Heat caused by fuel.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of furnace core improving coal utilizaton rate, including furnace core shell, furnace core shell are the cylindrical body of upper and lower opening, in furnace core shell
Portion is burner hearth；It further include combustion-supporting and combustion-supporting lid, after combustion-supporting lid and combustion-supporting assemble, inside forms ring chamber, external shape
Circlewise body；The inside air inlet for being connected to ring bodies inner space with ring chamber, ring bodies are provided on ring bodies inner sidewall
The outside air inlet for being connected to ring chamber with ring bodies outer space is provided on lateral wall；Combustion-supporting and the setting of combustion-supporting lid exist
Between the furnace core shell and stove hole of stove, and burner hearth is connected to stove hole.Coal fuel is placed by cylindrical body upper end opening.It is cyclic annular
Chamber is steady air current room, provides source of oxygen by outside air inlet, then provide more oxygen by inside air inlet for flame, into
And realize the effect or effect for promoting flame combustion.When fuel combustion is insufficient, the gases such as some carbon monoxide are had, by mentioning
For the unburned abundant gas being mingled in more oxygen more flame, efficiency of combustion can further improve.
Preferably, furnace core set is provided on furnace core shell lateral wall；Furnace core shell inner space is in a circular table shape, and rotary table
Upper radius be less than lower radius.This programme matches diminishing flame profile from the bottom to top, further increases flame combustion
Burn efficiency.

Side；Inside air inlet is arranged in cylindrical portion, and outside air inlet is arranged on annulus；The internal diameter of cylindrical portion is from the bottom to top gradually
It reduces.Cylindrical portion provides the necessary channel of flame, and more oxygen is provided when passing through flame, for burning.
Preferably, inside air inlet has been evenly arranged at least two along cylindrical portion annular, and inside air inlet
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 shell, 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

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 uses concrete material, and combustion-supporting and combustion-supporting lid, fire grate ontology and bracket use
Cast iron materials.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 present invention are: logical
It crosses cylindrical body upper end opening and places coal fuel.Ring chamber is steady air current room, provides source of oxygen by outside air inlet, then lead to
It crosses inside air inlet and provides more oxygen for flame, and then realize the effect or effect for promoting flame combustion.Fuel combustion is not filled
Timesharing has the gases such as some carbon monoxide, can be by providing the unburned abundant gas being mingled in more oxygen more flames
One step improves efficiency of combustion.After the furnace core is assembled on stove, the coal fuel that can be improved burning Unit Weight is produced
Raw heat.
