Description

449 130 ljudnivå. 449 130 sound level.

Den i publikationen presenterade och i kraven definierade eldstadsluckan uppfyller i första hand de båda sistnämnda ändamâlen.The fireplace door presented in the publication and defined in the requirements primarily fulfills the two last-mentioned purposes.

Ett ändamål med uppfinningen är att ta om hand alla even- tuellt utläckande bränngaser vid luck- och brännarsidan och skicka dessa tillbaka i pannan igen, trots att ett övertryck- råder i själva pannan gentemot omgivningen.An object of the invention is to take care of all any leaking fuel gases at the door and burner side and send these back into the boiler again, despite an overpressure prevailing in the boiler itself towards the surroundings.

För uppfinningen väsentliga kännetecken är angivna i patent- kravs 1 kännetecknande del.Essential features of the invention are set out in the characterizing part of claim 1.

Ett par utföringsformer av uppfinningen skall nedan beskrivas med hänvisning till bilagda schematiska ritningar.A couple of embodiments of the invention will be described below with reference to the accompanying schematic drawings.

Fig. 1 är ett vertikalsnitt genom övre delen av en övertrycks- panna försedd med en anordning enligt uppfinningen.Fig. 1 is a vertical section through the upper part of an overpressure boiler provided with a device according to the invention.

Fig. 2 är ett vertikalsnitt genom en i förhållande till fig. 1 modifierad panna.Fig. 2 is a vertical section through a boiler modified in relation to Fig. 1.

I pannluckan 1 som via exempelvis gångjärn är fäst till pannan 2 är på sedvanligt sätt fäst en oljebrännare 3 innehållande bl.a. en förbränningsfläkt 4 som pressar in förbränningsluft genom brännarhalsen 5 och in i pannan. Fläkten är oftast för- sedd med en ljuddämpningskâpa som dock icke tätar mot luckan.In the boiler door 1, which is attached to the boiler 2 via, for example, hinges, an oil burner 3 is contained in the usual manner, containing e.g. a combustion fan 4 which presses combustion air through the burner neck 5 and into the boiler. The fan is usually equipped with a sound-absorbing cover which, however, does not seal against the door.

Ett munstycke 6 finfördelar oljan som antändes. Rökgaserna vänder och passerar ett antal konvektionsrör 7 för att sedan samlas i det ringformade utrymmet 8, till vilket en skorstens- stos är ansluten (ej visat). Möjliga läckagevägar är i detta fall vid A, B och C.A nozzle 6 atomizes the ignited oil. The flue gases turn and pass a number of convection pipes 7 and then collect in the annular space 8, to which a chimney socket is connected (not shown). Possible leakage paths are in this case at A, B and C.

Huvudprincipen är att anordna tryckdifferenser, så att allt läckage är styrt på ett kontrollerat sätt och ej kan gå ut till omgivningen. På pannkonstruktionen enligt fig. 1 görs 449 1soj detta genom att en hel, eller till den normala ljuddämp- ningshuven kompletterande kåpa anbringas. Denna är öppen till omgivningen via en öppning 10 som är så dimensionerad att ett önskat undertryck erhålles inne i kåpan 9.The main principle is to arrange pressure differences, so that all leakage is controlled in a controlled manner and can not go out to the environment. On the boiler construction according to Fig. 1, this is done by fitting an entire cover, or supplementary to the normal sound attenuation hood. This is open to the environment via an opening 10 which is dimensioned so that a desired negative pressure is obtained inside the housing 9.

Läckage via A kan på så sätt aldrig tränga ut till omgiv- ningen. Läckage via B går ej direkt ut till omgivningen utan hamnar tillsammans med nedkylda rökgaser i det ringformade utrymmet 8. Läckage via C tas om hand genom ett ytterligare ringformat utrymme 11 (vilket naturligtvis inte behöver vara cirkulärt) och vilket är skapat med hjälp av en tätning 12.Leakage via A can thus never penetrate to the surroundings. Leakage via B does not go directly to the surroundings but ends up together with cooled flue gases in the annular space 8. Leakage via C is taken care of through an additional annular space 11 (which of course does not have to be circular) and which is created by means of a seal 12.

Utrymmet 11 står i förbindelse med undertrycket i kåpan 9 via en kanal 13 med tillräckligt stor genomströmningsarea i förhållande till läckageareorna, så att ett erforderligt undertryck skapas i utrymmet 11 gentemot omgivningen, så att någon läcka förbi tätningen 12 ej kan förekomma.The space 11 communicates with the negative pressure in the housing 9 via a channel 13 with a sufficiently large flow area in relation to the leakage areas, so that a required negative pressure is created in the space 11 towards the surroundings, so that no leakage past the seal 12 can occur.

Samma princip kan även användas på andra konstruktioner.The same principle can also be applied to other constructions.

Exempelvis visas i fig. 2 en s.k. säckpanna där det ring- formade utrymmet 11 och tätningen 12 finns markerade.For example, Fig. 2 shows a so-called sack pan where the annular space 11 and the seal 12 are marked.
