Description
Technical field
The utility model relates to the solid-fuelled burner of a kind of burning of particulate, is the solid-fuelled domestic stove of a kind of use biological particles shape specifically.
Background technology
In the existing domestic stove, common type is a coal stove.Its structure is: in the cylindrical shape furnace wall, forms the burner hearth of cylindrical space, in burner hearth, inserts solid fuel, and for example spherical coal cinder or honeycomb lump coal, solid fuel is in the burner hearth internal combustion.Upside at burner hearth is formed with upper shed, is used to add fuel.And, be provided with chamber stove and accessory with the corresponding position of upper shed burner hearth, a side of chamber has the outlet flue that is connected with chimney, chamber with the burner hearth upper shed over against top, position be provided with flame hole.Downside at burner hearth is provided with under shed, is used for air intake.And, be provided with fire grate at lower opening, be used to discharge the slag after the burning.Because form coke behind the coal combustion easily, the volume of the slag of formation is bigger, therefore, the opening on the fire grate or the size of perforate are bigger.In use, directly light because coal is difficult, the fuel that therefore need ignite earlier in burner hearth usually firewood or straw etc. are lighted easily, and then press coal cinder, coal cinder is progressively ignited.At first being ignited in the bottom of coal cinder burns, and is burned to the top of coal cinder then gradually.When coal cinder is about to burn totally, add new coal cinder, make initiate coal cinder continue to repeat original combustion process from bottom to top.
For above-mentioned existing domestic stove, the public has used for many years and and has been accustomed to, and the problems that exist in this stove and accessory are also ignored always.At first, the thermal efficiency is lower, and economy is relatively poor.Coal cinder burns from bottom to top, and when the burning of the bottom of coal cinder, flame is stopped by coal cinder top, makes available energy reduce, and is easy to generate cigarette; And when being burned to coal cinder top, the utilizability of flame is better, but coal cinder is about to burning totally, need replenish new coal cinder from the top, and flame is pressed in below the new coal cinder, has reduced available energy again.Secondly, the burning time of one stove coal cinder is about several hours, and as domestic stove (for example, family's usefulness of cooking), usually only need about half an hour to one hour, after using up, be difficult to will burning coal cinder extinguish, a stove coal cinder can only be burnt down usually, therefore, the domestic stove of burning coal cinder can cause unnecessary waste.Also have, coal cinder is difficult for lighting, and needs 20-30 minute ability to ignite fully usually, uses inconvenience.
At present, a kind of as reproducible alternative energy, biomass fuel more and more is subject to people's attention.Biomass fuel is to carry out moulding after biological materials such as for example stalk, straw, timber, wood chip and leaf are pulverized, and forms granular solid fuel.Though biomass fuel more and more comes into one's own, the present combustion furnace that utilizes granular biomass fuel has been confined to scale just economic feasibility, can only satisfy large medium-size boiler at present and use, and is difficult to be applied to average family and uses.
In view of the problem of above coal-fired domestic stove and the application of biomass fuel, therefore, be necessary to provide a kind of novel domestic stove that utilizes particulate biomass fuel, overcome the defective that existing coal stove exists.
The utility model content
The utility model is for a kind of domestic stove that utilizes particulate biomass fuel is provided, and this domestic stove is suitable for rural households to be used, and utilizes particulate biomass fuel to act as a fuel, easy to use and good economy performance.
The utility model provides a kind of domestic stove that utilizes particulate biomass fuel, and this domestic stove has the burner of tubular, and the inboard of this burner forms the combustion chamber of upper and lower opening; Arranged outside in the part that is positioned at downside at least of this burner has loading head, the bottom of this loading head extends to the below of combustion chamber and fire grate is installed, between the bottom of burner and fire grate, form the combustion zone, on the lateral wall of the bottom of loading head, offer air inlet, be provided with the charging aperture that is communicated in described combustion zone in the bottom of this loading head, the upper end of this loading head is formed with the feeding port that adds biomass fuel.
The structure of domestic stove of the present utility model has significant technique effect.In use, can add granular biomass fuel to loading head is inner from the feeding port between the outer wall of the upper end of loading head and burner, biomass fuel is motion downwards in loading head, charging aperture between the bottom by being formed on burner and the inwall of loading head enters into the bottom of burner and the combustion zone between the fire grate and burns.When burning, along with the negative pressure that burning produces, air enters into the combustion zone from the gap that the air inlet on the lower sides that is arranged on loading head passes between the biomass fuel, supplies with fresh air to the combustion zone.Because air inlet is arranged on the lower sides of loading head, thereby, can supply with fresh air fully near the combustion zone.Owing to only stay ashes seldom behind the biomass fuel combustion, there is not the material of coke shape, therefore can easily discharge from fire grate.Along with the discharge of ashes, be deposited in biomass fuel in the loading head and further tumble the combustion zone and burn by charging aperture.The domestic stove that the utility model provides simple in structure, and biomass fuel can be supplied with to the combustion zone by charging aperture automatically and continuously along with burning, and avoided the problem of the new interpolation fuel gland combustion front in the existing coal stove, make fuel fully to burn, improved efficiency of combustion.
According to the domestic stove that utilizes particulate biomass fuel described in the utility model, in one embodiment, described loading head has madial wall and described lateral wall, forms the space that gathers materials of described loading head between described madial wall and described lateral wall.Certainly, also loading head can be arranged to other structures, for example, in another embodiment, this loading head only has described lateral wall, forms the space that gathers materials of described loading head between the lateral wall of this loading head and the outer wall of burner.Further, described charging aperture is formed between the inner surface of lateral wall of the bottom of burner and loading head.Only have lateral wall and the structure of madial wall is not set for loading head, can use the outer wall of burner,, can make structure simpler like this, reduce the quantity of parts with the formation space that gathers materials.
According to the domestic stove that utilizes particulate biomass fuel described in the utility model, in one embodiment, the described space that gathers materials has the ring section and round the part setting that is positioned at downside at least of this burner.In another embodiment, described loading head forms more than one, and the space that gathers materials of each loading head has the fan ring section and partly round the part setting that is positioned at downside at least of this burner.Have the structure of fan ring section for the space that gathers materials, it is restricted or have other to be provided with when requiring the place to be set at this domestic stove, makes things convenient for the setting of this domestic stove.
