Opfindelsen angår en kedel til fyring med halmballer, hvor kedelen omfatter en i fyrkammeret anbragt bæreindretning til at bære ballerne.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a boiler with straw bales, the boiler comprising a carrier arranged in the firing chamber for carrying the bales.

Ved kedler af denne art fyrer man enten med de rektan-5 gulære halmballer, som smides ind direkte på fyrkammerets bund, eller rundballer, hvor ballerne stilles på højkant i fyrkammeret.Boilers of this kind are fired either with the rectangular yellow straw bales, which are thrown directly into the bottom of the firing chamber, or round bales where the bales are placed upright in the firing chamber.

I begge tilfælde opnår man imidlertid ikke den ønskede gode forbrænding af ballerne, idet de kun brænder fra 10 en og samme ende, samt at der ikke kan skabes tilstrækkelig luftcirkulation om ballerne.In both cases, however, the desired good combustion of the bales is not achieved, since they only burn from one and the same end and that sufficient air circulation cannot be created about the bales.

Formålet med opfindelsen er at angive en kedel af den i indledningen angivne art, hvor man opnår en jævn forbrænding af hele ballen og samtidig skaber den fornød-15 ne luftcirkulation om denne.The object of the invention is to provide a boiler of the kind specified in the introduction, whereby a uniform combustion of the whole bale is obtained and at the same time it creates the necessary air circulation thereon.

Dette opnås ifølge opfindelsen ved, at bæreindretningen har en drivaksel, der stikker ud gennem fyrkammeret og er indrettet til at kunne drives eksempelvis af en gearmotor, således at ballerne bibringes en lang-20 somgående rotation. Ved således at bibringe ballerne en rotation opnås en ensartet forbrænding af disse tillige med en øget luftcirkulation omkring ballerne.This is achieved according to the invention in that the carrier has a drive shaft protruding through the firing chamber and is arranged to be driven, for example, by a gear motor, so that the balls are provided with a slow rotation. By thus imparting a rotation to the bales, a uniform combustion of these is achieved, as well as an increased circulation of air around the bales.

Bæreindretningen for ballerne kan udformes på forskellig vis, ligesom den kan tilpasses alt efter, om man 25 benytter rektangulære eller runde halmballer. Bæreindretningen kan således være en vandret plade med eller uden huller eller en rist, således at asken falder ned på fyrkammerets bund, eller der kan være nogle fjederbelastede arme ud fra fyrkammerets sidevægge, som ra-30 ger asken ned. Drivakselen føres her hensigtsmæssigt 2 146305 gennem bunden i fyrkammeret, men den kan også gå gennem loftet. Bæreindretningen kan også være en tromle med huller eller lavet af tremmer med en vandret drivaksel, men mest hensigtsmæggsigt udgør drivakselen sam-5 tidig bæreindretningen for halmballerne, idet den har mindst ét, fortrinsvis to parallelle med akselen og til samme fastgjort spyd. Halmballerne presses da ind over drivakselen og spyddene. Længden af drivakselen og spyddene vælges således, at de ligger begravet i 10 halmen, hvorved de er isoleret mod varmepåvirkningen en stor del af tiden. Drivakselen føres hensigtsmæssigt ud gennem fyrkammerets endevæg, men kan anbringes i lågen, således at man kan stå udenfor og anbringe halmballerne på spyddene. Ved den lodrette anbringelse af 15 halmballerne kan der indrettes en skyllekanal eller lignende til fjernelse af asken på den side af ballen, som denne vil føre asken over mod.The support for the bales can be designed in different ways, and it can be adjusted according to whether rectangular or round straw bales are used. Thus, the carrier may be a horizontal plate with or without holes or a grate so that the ash falls on the bottom of the firing chamber, or there may be some spring-loaded arms from the side walls of the firing chamber which project the ash down. The drive shaft is conveniently passed through the bottom of the firing chamber here, but it can also pass through the ceiling. The carrier may also be a drum with holes or made of barrels with a horizontal drive shaft, but most conveniently the drive shaft constitutes at the same time the carrier for the straw bales, having at least one, preferably two, parallel to the shaft and for the same attached spear. The straw bales are then pressed over the drive shaft and the skewers. The length of the drive shaft and the spears are chosen such that they are buried in the straw, which is insulated against the heat effect a large part of the time. The drive shaft is conveniently extended through the end wall of the firing chamber but can be placed in the door so that one can stand outside and place the straw bales on the skewers. By the vertical positioning of the straw bales, a flushing channel or the like can be arranged to remove the ash on the side of the bale to which the ash will guide the ash.

Et udførelseseksempel for opfindelsen skal i det følgende forklares nærmere under henvisning til medføl-20 gende tegning, der viser fig. 1, længdesnit gennem en kedel ifølge opfindelsen og fig. 2, tværsnit gennem kedelen vist i fig. 1.An exemplary embodiment of the invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 is a longitudinal section through a boiler according to the invention; and FIG. 2, cross section through the boiler shown in FIG. First

På tegningen er vist en kedel af den art, der benyt-25 tes ved fyring med de såkaldte rundballer 1, der på højkant skubbes ind i kedelens fyrkammer 2.The drawing shows a kettle of the kind used in firing with the so-called round bales 1 which are pushed into the boiler 2 of the boiler on a high edge.

Kedelen omfatter en bæreindretning 3 bestående af en i kedelens længdemidtakse anbragt drivaksel 4, der er ført ud gennem kedelens endevæg, hvori den er lejret.The boiler comprises a carrier 3 consisting of a drive shaft 4 arranged in the longitudinal center axis of the boiler which is extended through the end wall of the boiler in which it is mounted.

30 Drivakselen 4 trækkes af en gearmotor 5 over et rem- 146305 3 træk 6. Parallelt med drivakselen 4 og fastgjort til samme er der to ekstra spyd 7.30 The drive shaft 4 is pulled by a gear motor 5 over a pulley 6. Parallel to the drive shaft 4 and attached to the same there are two additional jaws 7.

Når rundballen 1 føres ind i fyrkammeret 2, skubbes den ind over drivakselen 4, og de to ekstra spyd 7, 5 som sikrer, at drivakselen 4 fører rundballen 1 med rundt, når gearmotoren 5 starter. Udvekslingen er afpasset således, at ballen foretager 2-20 omdrejninger i timen, fortrinsvis 3-5 omdrejninger.As the round bale 1 is introduced into the firing chamber 2, it is pushed in over the drive shaft 4, and the two additional spears 7, 5 which ensure that the drive shaft 4 carries the round bale 1 around as the gear motor 5 starts. The exchange is adapted so that the bale makes 2-20 rpm, preferably 3-5 rpm.

Ved rundballens rotation sikres således en ensartet 10 forbrænding over hele ballen.Thus, by the rotation of the round bale, a uniform combustion is ensured over the entire bale.
