Abstract
Description
25 30 F 619 557 2 genom vridning av en knopp 13 på stången 11, kan denna bringas uppåt eller nedåt. By turning a knob 13 on the rod 11, it can be brought up or down.
Demia vridningsrörelse medför att även det inre röret 6 förskjuts uppåt eller nedåt, varvid röret 6 glider mot det stationära tätningsorganet 7.This rotational movement means that the inner tube 6 is also displaced upwards or downwards, whereby the tube 6 slides against the stationary sealing member 7.
Vid nedmatning av bränslet till förbränningsugnen 2 faller detsamma av sin egen tyngd från behållaren 1 via det inre röret 6 ned på keramikplattan 4, där det bildar en hög av en viss storlek. Vill man att denna bränslehög skall bli större, vilket innebär att förbränningen blir kraftigare och därmed värmeeffekten högre, drar man upp det inre röret 6 medelst stången 11. Regleringen av värrneeffekten sker sålunda synnerligen enkelt med hjälp av stången 11. Naturligtvis skulle vridningen av stången 11 kunna ske med hjälp av en elektrisk stegmotor i stället för manuellt.When feeding the fuel to the incinerator 2, the same falls of its own weight from the container 1 via the inner tube 6 down onto the ceramic plate 4, where it forms a pile of a certain size. If you want this fuel pile to be larger, which means that the combustion becomes stronger and thus the heating effect higher, you pull up the inner pipe 6 by means of the rod 11. The regulation of the heating effect is thus extremely simple with the help of the rod 11. Of course the rotation of the rod 11 can be done using an electric stepper motor instead of manually.
Förbränningsluften alstras av ett elektriskt drivet fläktorgan 14, som sprutar in luft till ett utrymme 15 utanför förbränningsugnen 2 via en kanal 16. Från detta utrymme tränger luften in i förbränningsugnen 2 via ett stort antal, mindre hål, av vilka vissa 17 är anordnade längs långsidorna på ugnen och placerade nära intill keramikplattan 4, medan andra hål 18 är anordnade i förbränningsugnens bakvågg 19.The combustion air is generated by an electrically driven fl means 14, which injects air into a space 15 outside the incinerator 2 via a duct 16. From this space the air penetrates into the incinerator 2 via a large number of smaller holes, some 17 of which are arranged along the long sides on the furnace and placed close to the ceramic plate 4, while other holes 18 are provided in the rear wall 19 of the incinerator.
Förbränningsugnen 2 och det omgivande utrymmet 15 omsluts av ett hölje 20, som har fonnen av en parallellepiped med kvadratisk eller rektangulär tvärsektion och innefattar en inre 21 och en yttre 22 plåt, vilka år åtskilda av en värmetålig isolering 23.The incinerator 2 and the surrounding space 15 are enclosed by a housing 20, which has the shape of a parallelepiped with a square or rectangular cross-section and comprises an inner 21 and an outer 22 plate, which are separated by a heat-resistant insulation 23.
I ett lämpligt hål i höljets 20 frontvägg är en rörstos 24 fastsatt, som är i direkt förbindelse med förbränningsugnen 2 och skjuter ut ett stycke utanför höljets frontvägg.In a suitable hole in the front wall of the housing 20, a pipe socket 24 is fixed, which is in direct connection with the incinerator 2 and projects a distance outside the front wall of the housing.
Denna rörstos 24 är avsedd att skjuta in i uppvärrnningsutrymmet i pannan vid dess hopkoppling med den uppfmningsenliga anordningen, varvid höljets/förbränningsugnens frontvägg ligger an mot pannans frontvägg. Vid förbränning av bränslet i ugnen kommer sålunda de bildade eldslågoma att kastas in i pannan via rörstosen 24 och sålunda värma pannvattnet.This pipe socket 24 is intended to slide into the heating space of the boiler when it is coupled to the device according to the invention, the front wall of the housing / incinerator abutting against the front wall of the boiler. Thus, when burning the fuel in the furnace, the fire flames formed will be thrown into the boiler via the pipe socket 24 and thus heat the boiler water.
Antändningen av bränslet sker med hjälp av en tändsticka eller liknande, som skjuts in till bränslet via ett tåndrör 25.The fuel is ignited by means of a match or the like, which is pushed into the fuel via a spark plug 25.
En väsentlig del i denna uppfinning är en luftkanal 26, som leder från fläktkanalen 16 till en sidoyta 27 på behållaren 1, och som sålunda erhåller luft från fläktorganet 14.An essential part of this invention is an air duct 26, which leads from the fan duct 16 to a side surface 27 of the container 1, and which thus receives air from the mating means 14.
Härigenom uppnår man två fördelar: För det första förhindras att rök och eld sprids uppåt via det inre röret 6 till behållaren 1, ty den luft som' sprutas in i behållaren skapar ett övertryck därstädes. För det andra möjliggör övertrycksluften i behållaren att det skapas en luftström nedåt genom det inre röret 6 till brånslehögen. Denna luftström, som träffar Psssosslsoo/ÖWMD { , . . . a 519 557 3 bränslehögens topparti, fungerar som kompletterande förbränningsluft och bidrar tillsammans med kupolformen på förbränníngsugnen till att hela bränslehögen brinner samtidigt, vilket gör förbränningen av bränslet synnerligen effektiv.In this way two advantages are achieved: Firstly, smoke and fire are prevented from spreading upwards via the inner pipe 6 to the container 1, because the air which is injected into the container creates an overpressure there. Secondly, the overpressure air in the container enables an air flow downwards through the inner pipe 6 to the fuel pile. This airflow, which hits Psssosslsoo / ÖWMD {,. . . a 519 557 3 the top part of the fuel pile, functions as supplementary combustion air and together with the dome shape of the incinerator contributes to the entire fuel pile burning at the same time, which makes the combustion of the fuel extremely efficient.
I flg. 1 visas den uppñnningsenliga anordningen placerad på ett förflyttningsbart stativ 28. Härigenom kan anordningen enkelt förflyttas från pannan vid teknisk översyn.I fl g. 1 shows the device according to the invention placed on a replaceable stand 28. As a result, the device can be easily removed from the boiler during technical inspection.
Uppñnningen är naturligtvis ej begränsad till den angivna utföringsformen utan kan modifieras inom ramen för efterföljande patentkrav.The invention is of course not limited to the specified embodiment but can be modified within the scope of the appended claims.
