Abstract
The utility model provides a steam blows sediment formula bagasse boiler has grate, its characterized in that at furnace bottom tilting fixed: this grate includes the framed bent, is fixed with row's piece of seting up the wind gap on the framed bent, is fixed with a plurality of steam jet on row's piece, and every steam jet all is connected with the steam system who is located the framed bent below. The utility model discloses mainly be applied to the bagasse boiler to not only enable the bagasse and fully burn, thereby improved the thermal efficiency of boiler, but also can avoid phenomenons such as stoker surface coking, long -pending heat to take place, and then prolonged the life of grate.
Description
Technical field
The utility model relates to field of boilers, and particularly a kind of take bagasse as the bagasse boiler of fuel.
Background technology
Bagasse is the discarded object produced in sugar refining technology process, but is also valuable fuel energy.If it can be used as industrial refuse directly to abandon, not only waste this energy, but also pollute the environment; So at present all using bagasse as boiler oil, thus the steam that boiler produces is used for power supply and steam supply, finally the not only Appropriate application energy, also protects social environment.
But the moisture of bagasse is high, calorific capacity is low, the ash melting point causing its burning to produce is lower, the air port of this lime-ash very easily on shutoff fire grate, be not easy to bagasse Thorough combustion on the one hand, cause stoker surface coking, accumulated heat on the other hand, finally have impact on the service life of fire grate.And the fire grate of existing bagasse boiler a kind of be conventional large scale fire grate, this fire grate not only complex structure, cost is high, and the very easily coking of this stoker surface, accumulated heat, cause its service life shorter, thus gradually eliminate by market.Another kind is water-cooled furnace grate, although its surface temperature can be reduced by water circulation by this fire grate, thus extend the service life of self, but the temperature that also can reduce in burner hearth, thus cause dry incomplete, insufficient, the more high chain effect of unburned carbon in flue dust of burning of bagasse, and then cause a large amount of flying dusts and not clean-burning bagasse coking on this grate surface, and block each air port, finally cause the thermal efficiency of boiler very low.
Utility model content
The purpose of this utility model is low in order to solve the existing bagasse boiler thermal efficiency, and in boiler, bagasse burns insufficient technical problem, and then provides a kind of steam and blow slag formula bagasse boiler.
The technical scheme that the utility model technical solution problem adopts is:
A kind of steam blows slag formula bagasse boiler, tilts to be fixed with fire grate at burner hearth bottom.This fire grate comprises framed bent, is fixed with the screening of offering air port on framed bent, screening is fixed with several steam jets, and each steam jet is all connected with the vapour system be positioned at below framed bent.
By implementing technique scheme, high steam sprays in burner hearth by steam jet by vapour system, and bagasse in burner hearth and flying dust under the triple role of steam, flue gas and air in suspended state, so not only be beneficial to the drying of bagasse, and bagasse and flying dust can also be made to realize suspension combustion, and then reach clean-burning object.Meanwhile, utilize steam to blow slag and not only can not reduce temperature in burner hearth, it can also be made to maintain about 900 °.So in high temperature environments, steam and fuel carbon generation chemical reaction H
2o+C=H
2+ CO, and the H produced
2, CO is all the inflammable gases contributing to bagasse after-flame in burner hearth.Therefore, the utility model not only can make bagasse Thorough combustion, thus improves the thermal efficiency of boiler, and the phenomenons such as stoker surface coking, accumulated heat can also be avoided to occur, and then extends the service life of fire grate.
In order to avoid the blocking of fire grate uptake better, the injection direction of each steam jet is all parallel with stoker surface.
Based on technique scheme, the injection direction of steam jet is identical.The object of clearing up step by step can be realized at stoker surface like this, and then better avoid the blocked phenomenon in fire grate air port and occur.
Steam jet is fixed on the surface of fire grate.
Screening is spliced by some sub-screenings, and steam jet is fixed on the surface of sub-screening.
Pre-embedded steel slab seal welding on framed bent and coagulation soil matrix.
For the ease of light a fire time place fuel, run time poke fire, blowing out time scarfing cinder, the technical program is being positioned at above fire grate, and the left and right side wall of burner hearth is respectively equipped with fire door.
In order to make the easier Thorough combustion of bagasse in burner hearth, the technical program is being positioned at above fire grate, the rear wall of burner hearth is provided with from bottom to up successively near the one-level overfiren air port of fire grate, the secondary overfiren air port higher than charging aperture, and three grades of overfiren air ports above secondary overfiren air port.Three overfiren air ports of such setting, more easily making when coordinating with flue gas and steam bagasse and flying dust be suspended in burner hearth, more easily realizing clean-burning object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
In figure: 1. burner hearth, 2. fire grate, 3. vapour system, 11. charging apertures, 12. fire doors, 13. one-level overfiren air ports, 14. secondary overfiren air ports, 15. 3 grades of overfiren air ports, 21. framed bents, 22. screenings, 23. steam jets, 221. sub-screenings.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model is the same with prior art, is also fixed with fire grate 2 in the bottom angled of burner hearth 1, and the front wall of burner hearth 1 is provided with the charging aperture 11 sprayed into for bagasse; Also be provided with bellows in the below of fire grate 2, these bellows can blow in burner hearth 1 air below fire grate 2 simultaneously, reduce the heat of fire grate 2 on the one hand, contribute to bagasse and flying dust suspension on the other hand.And in the utility model, the structure that mainly there is fire grate 2 and burner hearth 1 liang of aspect is improved.
As shown in Figure 1 and Figure 2, a kind of steam blows slag formula bagasse boiler, and its fire grate 2 comprises framed bent 21, is fixed with the screening 22 of offering air port on framed bent 21, the surface of screening 22 is fixed with several steam jets 23, each steam jet 23 is all connected with the vapour system 3 be positioned at below framed bent 21.The injection direction of above-mentioned steam jet 23 is parallel with fire grate 2 surface, and injection direction is consistent.
In actual use, for the ease of the installation and maintenance of screening 22, screening 22 can also be designed to be put together by some sub-screenings 221, if certain sub-screening 221 damages, so just can safeguard by pointed carrying out.In order to framed bent 21 being more firmly fixed on the bottom of burner hearth 1, can by above-mentioned framed bent 21 seal welding on the pre-embedded steel slab of coagulation soil matrix.
The utility model conveniently places fuel when lighting a fire, poke fire when running, blowing out time scarfing cinder etc., be also positioned at above fire grate 2, the left and right side wall of burner hearth 1 be respectively equipped with fire door 12.Secondly, more easily float in burner hearth 1 to make bagasse, flying dust, and then Thorough combustion, also burner hearth 1 rear wall and be positioned at above fire grate 2, be provided with successively from bottom to up near the one-level overfiren air port 13 of fire grate 2, the secondary overfiren air port 14 higher than charging aperture 11, and three grades of overfiren air ports 15 above secondary overfiren air port 14.
Each embodiment above-mentioned, under the prerequisite that there is not conflict, all may be combined with and uses.
