Abstract
The utility model discloses a long stalk gasifying stove, belonging to the technical field of stove. The long stalk gasifying stove has the technical proposal of comprising a hearth provided with grates; the bottom of the heath is a stove ash chamber which is opened with an ash outlet; the outer side of the stove wall of the hearth is provided with a secondary wind channel which consists of a thermal insulation layer, and the bottom of the secondary wind channel is opened with wind inlets, wherein, the stove wall is opened with a plurality layers of secondary wind inlets; the stove wall at the side part of the hearth is provided with an inclined thermal decomposition chamber which is communicated with the middle lower part of the hearth. The long stalk gasifying stove with the structure can fill the long stalk into the hearth at any moment when in the use process; further more the stove body is internally provided with the secondary wind chamber and the wind inlets so that the utility model is characterized in convenient use, high burning temperature and long service life.
Description
Technical field
The utility model belongs to the combustion stove technical field, relates in particular to the long stalk gasifier that a kind of family uses.
Background technology
At present, China remains a large agricultural country, and the annual number that produces is with 10,000,000,000 tons straw.These stalk parts are gone back outside the Tian Zaofei, and still some is used as fuel heating burning.But the burning of using general cooking stove stalk is insufficient, fuel value is lower, easily causes environmental pollution.The patent No. is to disclose a kind of " domestic direct-firing gasifying type cleaning stalk furnace " for the utility model patent of CN2523764Y ZL01275188.X, Granted publication number.The structure of this stalk furnace constitutes by be fixed with the burner of doing dismounting on the burning bucket.During use, burner is taken, separated with the burning bucket, then loose fuel such as stalk are filled into tamping in the burning bucket, the igniting that afterwards burner resetted is used.This domestic direct-firing gasifying type cleaning stalk furnace exists defective: owing to constitute the limited length of this stalk furnace burning bucket, therefore it must be pulverized when adding stalk; This stalk furnace can not the secondary filler in use, must blowing out during filler, and long-time the use is restricted; This stalk furnace in use easily produces tar and condensed water, and tar is nonflammable and can produce peculiar smell, influences environment, and condensed water easily produces corrosion to the furnace wall, influences its service life.
The utility model content
The purpose of this utility model just provides has simple in structure, repeatedly filler and a kind of long stalk gasifier easy to use.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of long stalk gasifier, its structure include the burner hearth that is provided with fire grate, the ashes chamber that has ash hole, the oblique pyrolysis chamber that is communicated with it that is provided with on the furnace wall of described burner hearth sidepiece.
Its additional technical feature comprises: the angle of described pyrolysis chamber and described tweer is 15---and 45; The import of described pyrolysis chamber is positioned at the middle and lower part of described burner hearth; Have the secondary air mouth of several layers on the furnace wall of described formation burner hearth, described furnace wall arranged outside has the bottom to have the secondary air duct of air inlet; The described secondary air duct outside is a heat-insulation layer; Be provided with the blast pipe that a bottom is communicated with the ashes chamber in the described burner hearth; Described blast pipe outlet is provided with pipe cap.
A kind of long stalk gasifier provided by the utility model compared with prior art, have the following advantages: one, since the sidepiece of body of heater be provided with burner hearth together with the pyrolysis chamber with certain altitude, therefore, in use can insert long stalk in the burner hearth at any time, stalk need not to pulverize and can add at any time, therefore has characteristics easy to use; They are two years old, owing in body of heater, be provided with secondary air chamber, can in burner hearth, replenish enough oxygen in the use, make the stalk in the burner hearth to be fully burned, improved its ignition temperature, the temperature in the body of heater chamber of this long stalk gasifier can reach more than 800 ℃ after testing, can be so that the tar that is produced burns, condensing water vapor, overcome the tar smell to the corrosion of the pollution of environment and condensed water, service life of having improved stalk gasifier to the furnace wall.
Description of drawings
As figure is the structural representation of long stalk gasifier.
The specific embodiment
Below in conjunction with accompanying drawing the long gasifying stalk furnace structure that the utility model provides is elaborated.
As shown in the figure, the structural representation of the best real-time mode of long stalk gasifier that provides for the utility model.Promptly the structure of this long stalk gasifier includes the burner hearth 2 that is provided with fire grate 1, and its bottom is for having the ashes chamber 4 of ash hole 3, and the arranged outside in the furnace wall 5 of burner hearth has the bottom that constitutes with heat-insulation layer 6 to have the secondary air duct 8 of air inlet 7.Wherein have the secondary air mouth 9 of several layers on the furnace wall 5.The oblique pyrolysis chamber with certain altitude 10 that is communicated with the middle and lower part of burner hearth that is provided with on the furnace wall of burner hearth sidepiece.
Its use principle is: at first stalk (stalk that does not especially have pulverizing) is filled in the burner hearth by the pyrolysis chamber and lighted a fire, take fire under the state that ash hole is opened.Closing ash hole when the temperature in the burner hearth reaches more than 500 ℃ gets final product.Can in burner hearth, insert stalk by the pyrolysis chamber at any time after straw burning in the burner hearth is intact.
Convenient in order to add stalk, make the included angle A of pyrolysis chamber and tweer be set in 15---between 45 degree.
In order to make that further stalk can fully burn in the burner hearth, in burner hearth, be provided with the blast pipe 11 that a bottom is communicated with the ashes chamber, and being provided with pipe cap 12 in the outlet of this blast pipe, this pipe cap 12 can improve the combustion rate in the burner hearth so that the air that enters in the burner hearth distributes uniformly.
Claims (7)
