A kind of biomass combustion furnace
Technical field
The present invention relates to a kind of combustion furnace, more particularly, to a kind of biomass combustion furnace.
Background technology
Energy problem is one of severe challenge of 21 century facing mankind.In recent years, develop rapidly with economic, China
Energy problem also day by day show especially.Energy problem becomes a difficult problem for countries in the world facing, and fossil energy is not only non-renewable,
Reserves are limited, and discharge substantial amounts of carbon dioxide, nitrogen, sulfur oxide and some other harmful gass after burning, seriously dirty
Contaminate environment, lead to many ecological problems such as greenhouse effect, global warming, the reduction of living species multiformity, desertification.Mesh
Biomass combustion furnace used by the front fertile machine for system has a following shortcoming:
1st, need plus a heat converter is to adjust temperature it is impossible to reasonably utilize heat energy, lead to thermal energy consumption serious.
2nd, grate can not rotate it is impossible to make fuel be fully burned in a combustion chamber.
For disadvantage mentioned above, the invention provides a kind of improved biomass combustion furnace is solving the above problems.
So-called biomass fuel refers to biomass granule fuel (commercially available), mainly the thing containing straw, wood flour, melon seed cases etc.
Matter, if burn down complete in combustion furnace internal combustion, relatively of reduced contamination.
Content of the invention
It is an object of the invention to provide a kind of biomass combustion furnace, to solve above-mentioned problem.
For achieving the above object, the technical solution of the present invention is: a kind of biomass combustion furnace, including feed arrangement,
Oxygen supply igniter and combustion furnace it is characterised in that:

14 connections, equipped with feeding screw axle in this feed pipe, one end of this helical axis is connected with motor 3 by sprocket wheel 8, and the one of feed pipe
End is connected with burner hearth 25;
B. described oxygen supply igniter includes oxygen supply blower fan 2, oxygen supplying tube 26, butterfly valve 4, one end of oxygen supplying tube 26 and oxygen supply wind
Machine 2 connects, and it is corresponding with the lower section of grate 18 that the other end passes through butterfly valve 4;
C. described combustion furnace includes igniter 15, burner hearth 25, grate 18, steering gear 16, and igniter 15 is built with electricity
Resistance silk, grate 18 is connected with steering gear 16, and this steering gear is connected with motor 3 with sprocket wheel 9 by drive shaft 10.
Described burner hearth 25 is the burner hearth that interior finishing has fire resisting mud layer 20, and dust arrester 21 and blower fan are passed through in its top
24 are connected with crater 23, and the upper peripheral of described burner hearth 25 is additionally provided with hot-water heating system 27, and this device is by water inlet 28, goes out
The mouth of a river 22 and the intercalated water sleeve of water tank composition.
Described grate 18 is rotatable arch grate.
The invention has the beneficial effects as follows:
1st, biomass granule fuel is directly blown out after stove chamber inner combustion by traditional combustion stove by crater, and shortcoming is: institute
Need temperature uncontrollable, it will supporting equipment is had an impact (such as: temperature is too high, to equipment material, using have certain
Impact);Produced heat energy is not clean, and substantial amounts of dust is contained in the inside, if not carrying out dust removal process, it will supporting is set
Have impact (such as: blocking);If corollary equipment has specified temp setting, need to fall his heat energy value, so have phase
When thermal waste, and as need to be solved above shortcoming, the also equipment that is necessary for is supporting with it, so will increase body
Long-pending, for the fabricating yard of limited area, much unnecessary trouble will be brought.For disadvantage mentioned above, the present invention will be traditional
Crater, from the design of side, has made into from roof of the furnace air-out, added with dedusting and temperature regulating device in the middle of burner hearth and air outlet
(hot-water heating system), principle: when leaving air temp is too high or when needing cooling to reach certain setting temperature, open this device, lead to
The principle of subcooled water heat absorption, is lowered the temperature, (temperature regulating device is the device of a water circulation).Certainly, when reaching design temperature, lead to
Discharge in water-carrying groove is keeping constant temperature.Heated water can do other purposes, reduces the waste of heat energy.
2nd, traditional combustion stove grate can not rotate it is impossible to make fuel be fully burned in a combustion chamber, and the present invention will
Grate is improved to rotatable arch grate, so that fuel is fully burned in combustor (burner hearth), thus improve thermal effect
Rate, simultaneously grate adopt the rotatable design of arch, the ashes after burning can be made, be more easily discharged to cylinder of skimming, reduce
Ashes in combustor.
3rd, by the design of hot-water heating system, the temperature required for outlet can be adjusted, it is possible to use unnecessary thermal source, can
The water of heating is added directly in the middle of the fertile machine of system, you can with improving material temperature and supplementary material moisture content, can serve as it again
He.
