Definitions
- the invention relates to a device for burning and gasification of solid Biomasses in a combustion chamber according to the preamble of claim 1.
- Such Method is already known from document US-A-4 421 064.
- the bales or the biomass are largely crushed and pulverized. After a possible drying, the so prepared Biomass fed to a special stationary or circulating furnace. Different to With coal, however, this preparation is extremely expensive and energy-consuming, so it is here to a rarely used and for small systems usually too complicated procedure is.
- the invention has therefore set itself the goal of a method for burning and To provide gasification of solid biomass in a combustion chamber in which neither consuming Boiler constructions are needed, nor a special preparation of biomass before the burning is necessary.
- FIG. 1 shows a section through a Inventive device for carrying out the method in a first Embodiment is;
- Fig. 2 shows the same device with a burn-up inserted bales;
- FIG. 3 shows a section through a device for Implementation of the method of this first embodiment along the line A-A in Fig. 1.
- the Fig. 4, 5, 6 and 7 respectively through further cuts Devices for carrying out the method according to the invention in each case further Embodiments.
- a bale 1 pressed from biomass is introduced as a whole Closure member 2 placed in a lock chamber 3 of the device according to the invention.
- the bale 1 by a Feed channel 5 is pushed continuously or stepwise against the combustion chamber 6.
- the feed channel 5 z on its outside. With cold ones Combustion air or can be cooled with water.
- the feed channel 5 is connected via a supply line 7 with an inert gas, for example with Steam or a flue gas, applied to burn back into the lock chamber. 3 to avoid.
- an inert gas for example with Steam or a flue gas
- a ZündT 8 arranged in the combustion chamber 6 is against the end face of the inserted bale 1 .
- This ignition screen 8 which is designed to be heated for primary ignition can be, is only a weakly cooled surface with very good storage capacity. at Practical testing has thick refractory sheet and a refractory Masonry mass proven. Through the partially or completely occurring Combustion, the Zündhold 8 is hot and it is thereby the throwing back of Radiant heat on the bale 1 allows.
- the amount of air is such that usually only a partial Combustion, so a gasification takes place.
- an ash hopper 12 for collecting the left over permanent ash; this ash funnel 12 has for post-oxidation of the ash components on bottom end Ausbrandluftdüsen 13 and below an ash sluice 14 for the Burnt ash on. The ash can be removed with the aid of this ash sluice 14 become.
- the gas released during the combustion of the biomass passes from the combustion chamber 6 a fuel gas channel 15 in a Nachverbrennungsraum 16.
- this Nachverbrennungsraum 16 can via secondary air nozzles 17 substantially transverse to Main direction of the gas, the secondary air for complete afterburning of the gas be injected.
- a bale 1 is inserted into the feed channel 5.
- This Feed channel 5 has the shape of a square placed on top. This form the feed channel 5 is therefore expedient because the bale 1 on the lower sides of the Feed channel 5 rests and thus remains only in the upper area a space. loose and detached fuel parts of the bale 1 thereby accumulate in the trough of Feed channel 5 and are pushed by the next bale in the combustion chamber 6 to there to be burned or gassed.
- a bale 1 is inserted into the combustion chamber 6.
- a Primary air blower 19 is air via an air line 20 of a flow switch 21 fed.
- This flow switch 21 distributes alternately the air to be blown into the Primary air ducts 22 ', 22 "and 22' '' by means of schematically illustrated trim tabs 23
- the amount of air flow supplied can be changed individually.
- a bale 1 is inserted into the combustion chamber 6.
- the air nozzles 24 are not arranged directly opposite the feed channel 4 in this embodiment, but they are slightly shifted in the direction of the post-combustion chamber 16.
- the Air nozzles 24 are inclined downwards, so that the air jets of the injected air are inclined relative to the feed direction of the bale 1.
- the air nozzles 24 could not in Be offset in the direction of the post-combustion chamber 16, but in the direction of Ash hopper 12, wherein in this embodiment, the air nozzles 24 upwards in the direction the bale 1 would be inclined.
- a feed device 27 pushes the bale 1 on a grate 28 'of the Combustion chamber 28.
- the bale 1 is completely (and not successively in accordance with the burning of the bale 1) inserted into the combustion chamber 28.
- the primary air line 30 a (only schematically illustrated) telescopic piece 31 on.
- a bale 1 is inserted into a combustion chamber 28.
- Air nozzles 32'and 32 " are tilted downwards and depending on the burning of the bale 1 from above down with air. This has the consequence that the injected air in each case in strikes a similar distance on the surface of the bale 1, and a uniform Burning caused.
