Description
Gass- eller oljeoppvarmet varmtvannskjele. Gas or oil-heated hot water boiler.
Foreliggende oppfinnelse angår gass- eller oljeoppvarmede varmtvannskjeier av den art hvor vannrommet består av to liggende, konsentrisk i hverandre innstukne vannmantler, som står i forbin-delse med hverandre gjennom oventil og nedentil anbrakte, fortrinnsvis gjennom spalten mellom mantlene gående forbindelseskanaler, og ved hvilke det går et sirkulasjonsrør mellom den øvre og nedre del av den ytre vannmantel. The present invention relates to gas- or oil-heated hot water boilers of the kind where the water space consists of two lying, concentrically inserted water jackets, which are connected to each other through connection channels arranged above and below, preferably through the gap between the jackets, and by which the runs a circulation pipe between the upper and lower part of the outer water jacket.
Ved varmtvannskjeler av denne type foreligger det store vanskeligheter med å opprettholde en jevn temperaturfordeling av kjelevannet, dels mellom de to vannmantler, dels innen hver enkelt vannmantel, og da særlig i den indre, i hvilken flammen oppstår og forbrenner. With hot water boilers of this type, there are great difficulties in maintaining an even temperature distribution of the boiler water, partly between the two water jackets, partly within each individual water jacket, and especially in the interior, in which the flame arises and burns.
Ved varmtvannskjelen ifølge oppfinnelsen overvinnes disse vanskeligheter. Kjelen er av den art som har liggende vahnrom som,omslutter brenneren og hvor. det mellom vannrommets øvre og nedre del løper et sirkulasjonsrør i .hvilket munner ut et;injektormunnstykke, gjennom, hvilket, det nedkjølte returvann fra det varmesystem som er forbundet med kjelen innføres, slik. at det gjennom sirkulasjonsrøret oppretthpldes en kraftig strømning av med varmt vann fra kjelens øvre del blandet nedkjølt returvann, The hot water boiler according to the invention overcomes these difficulties. The boiler is of the type that has a horizontal chamber that surrounds the burner and where. between the upper and lower parts of the water space runs a circulation pipe in which an injector nozzle exits, through which the cooled return water from the heating system connected to the boiler is introduced, as follows. that a strong flow of cooled return water mixed with hot water from the upper part of the boiler is created through the circulation pipe,
og kjelen ifølge oppfinnelsen karakteriseres ved at vannrommet på and the boiler according to the invention is characterized by the water space on
i og for seg kjent måte består av to liggende, konsentrisk i hverandre innskutte vannmantler som kommuniserer med hverandre gjennom på kjent måte nedentil og oventil anbrakte, fortrinnsvis gjennom spalten mellom mantlene passerende forbindelseskanaler, og at, sirkulasjonsrøret munner ut i den ytre vannmantel gjennom et injektormunnstykke hvis munning er anbrakt rett under den nedre forbindelseskanal mellom yannmantlene et så langt stykke nedenfor kanalen at det oppnås en ønsket fordeling av returvannblandingen på den ytre og den indre vannmantel.. in a known manner consists of two lying, concentrically cut into each other water jackets that communicate with each other through connecting channels arranged below and above in a known manner, preferably passing through the gap between the jackets, and that, the circulation pipe opens into the outer water jacket through an injector nozzle whose mouth is located directly below the lower connecting channel between the water jackets so far below the channel that a desired distribution of the return water mixture is achieved on the outer and inner water jackets..
Det vesentlig nye ved kjelen ifølge oppfinnelsen er at The essential novelty of the boiler according to the invention is that
den har et sirkulasjonsrør som gjennom et injektormunnstykke munner ut i den nedre delen av kjelen idet herved oppnås en effektiv blan-ding av returvannet og det varme vannet fra kjelens øvre del, it has a circulation pipe which, through an injector nozzle, opens into the lower part of the boiler, whereby an efficient mixing of the return water and the hot water from the upper part of the boiler is achieved,
samtidig som det blir en jevnere fordeling av vann til den ytre og indre vannkappen. Det er fra norsk patent nr. 106 243 kjent en lignende kjele, men denne har intet sirkulasjonsrør som løper direkte mellom den øvre og den nedre delen av kjelen. Riktignok viser patentskriftet at det er anordnet en dyseaktig utvidelse av forbindelseskanalen, men en kan ved en slik anordning ikke opp-nå den samme virkningen på fordelingen av.returvannet.som. foreliggende oppfinnelse innebærer. at the same time as there is a more even distribution of water to the outer and inner water jacket. A similar boiler is known from Norwegian patent no. 106 243, but this has no circulation pipe that runs directly between the upper and lower parts of the boiler. Admittedly, the patent document shows that a nozzle-like expansion of the connection channel is arranged, but such an arrangement cannot achieve the same effect on the distribution of the return water as. present invention involves.
Oppfinnelsen.skal beskrives under nærmere henvisning til vedlagte,tegning, hvor: The invention shall be described with further reference to the attached drawing, where:
Fig. 1 viser et vertikalt aksialsnitt gjennom kjelen, og Fig. 1 shows a vertical axial section through the boiler, and
Fig. 2 viser et vertikalt tverrsnitt langs linjen II-II Fig. 2 shows a vertical cross-section along the line II-II
på fig. 1. on fig. 1.
Ifølge tegningen består varmtvanns kjelens vannrom av en ytre begerformet vannmantel 10, og en i denne konsentrisk innstukket indre vannmantel 11 i form av en hulsylinder. De to vannmantler er forbundet med hverandre gjennom nedentil og oventil anordnede kanaler 12 og 13, som passerer diametralt gjennom det ringformede spalterom 14 mellom vannmantlene. Den ikke viste olje- eller gassbrenner er anbrakt sentralt i den fremre ende av den indre vannmantel 11, på innsiden båret av en frontdør 15 som kan åpnes. Flammen dannes og forbrennes inne i den indre vannmantel 11, orien-tert i dennes lengderetning. Røkgassene fra forbrenningen passe- According to the drawing, the hot water boiler's water space consists of an outer cup-shaped water jacket 10, and an inner water jacket 11 inserted concentrically into this in the form of a hollow cylinder. The two water jackets are connected to each other through below and above arranged channels 12 and 13, which pass diametrically through the annular gap space 14 between the water jackets. The oil or gas burner, not shown, is located centrally at the front end of the inner water jacket 11, on the inside supported by a front door 15 which can be opened. The flame is formed and burned inside the inner water mantle 11, oriented in its longitudinal direction. The flue gases from the combustion pass
rer via et indre vendekammer 16 gjennom spalterommet 14 mellom de to vannmantler, og videre via et fremre vendekammer 17 gjennom en sats av røkgasser 18, som i jevn fordeling passerer gjennom den ytre vannmantel 10 til et samlekammer 19 ved den bakre ende av kjelen, og deretter ut gjennom røkrøret 20 til den ikke viste skor-sten. moves via an inner turning chamber 16 through the gap 14 between the two water jackets, and further via a front turning chamber 17 through a batch of flue gases 18, which pass in uniform distribution through the outer water jacket 10 to a collection chamber 19 at the rear end of the boiler, and then out through the flue 20 to the chimney, not shown.
I en kjele av den viste konstruksjon opptas en meget bety-delig del av varmeavgivningen fra flammen av røkgassene og den indre vannmantel 11. I denne, som av dimensjonsårsaker har et lite vann-volum, er det forbundet med vanskeligheter å beherske vanntemperaturen. Disse vanskeligheter er ifølge oppfinnelsen overvunnet på følgende måte. In a boiler of the construction shown, a very significant part of the heat output from the flame is taken up by the flue gases and the inner water jacket 11. In this, which for dimensional reasons has a small water volume, it is associated with difficulties in controlling the water temperature. According to the invention, these difficulties are overcome in the following way.
Mellom toppen og bunnen av kjelen er innkoplet et sirkula-sjonsrør 21, som løper fritt utenfor kjelen. Oventil i dette rør innføres det nedkjølte returvann fra det ikke viste varmesystem ved hjelp av et i røret innstikkende munnstykke 22. Ved injek-sjonsvirkning blandes det nedkjølte returvann effektivt med det fra kjelens topp uttatte varme vann, og samtidig sikres en kraftig strømning ned gjennom sirkulasjonsrøret. Fra den: nedre ende av dette innføres blandingen i kjelens nedre del gjennom et injektormunnstykke 23. Dette er slik plassert at det munner ut midt under den nedre forbindelseskanal 12 mellom de to vannmantler og i noen avstand nedenfor nevnte kanal. På grunn av vanntilførselen til den indre mantel 11 oppstår en kraftig oppadrettet strømning gjen- A circulation pipe 21 is connected between the top and bottom of the boiler, which runs freely outside the boiler. At the top of this pipe, the cooled return water from the heating system, not shown, is introduced by means of a nozzle 22 that sticks into the pipe. In the case of injection, the cooled return water is effectively mixed with the hot water drawn from the top of the boiler, and at the same time a strong flow down through the circulation pipe is ensured . From the: lower end of this, the mixture is introduced into the lower part of the boiler through an injector nozzle 23. This is positioned so that it opens out in the middle below the lower connecting channel 12 between the two water jackets and at some distance below the aforementioned channel. Due to the water supply to the inner mantle 11, a strong upward flow occurs again.
nom denne. Ved hjelp av den nedre forbindelseskanal 12 kan vann-innstrømningen rettes slik at det oppnås god sirkulasjon også i den indre ende av den mot denne avsmalnende vannmantel. I den ytre vannmantel 10, som har store varmeopptagende flater, oppnås natur-ligvis også en kraftig strømning oppover. Ved plassering av in-jektormunnstykket 23 i passende avstand under den nedre forbindelseskanal 12 kan en hovedsakelig selvregulerende fordeling av returvannblandingen til den ytre og til den indre vannmantel oppnås nom this one. With the help of the lower connection channel 12, the water inflow can be directed so that good circulation is also achieved at the inner end of the water jacket which tapers towards it. In the outer water jacket 10, which has large heat-absorbing surfaces, a strong upward flow is naturally also achieved. By placing the injector nozzle 23 at a suitable distance below the lower connection channel 12, an essentially self-regulating distribution of the return water mixture to the outer and to the inner water jacket can be achieved
under innvirkning av de termiske, krefter som oppstår under oppT varmingen av ..vannet i kjelens man ti er-.. Et underskudd i tilfør-, selen av relativt- nedkjølt returvannblanding, f.eks. til den indre mantel, resulterer i en viss temperaturstigning i denne, som umiddelbart medfører en økning av den termiske kraft, og der-med en økning av mengden innstrømmende temperert returvannblanding inntil en likevektstilstand er oppnådd. Ved oppfinnelsen er altså tilveiebrakt dels en utjevning av vanntemperaturen innen hver vannmantel, dels en slik fordeling av det kaldere returvann på- under the influence of the thermal forces that arise during the heating of the ..water in the boiler's man ten is-.. A deficit in the supply-, the seal of relatively- cooled return water mixture, e.g. to the inner mantle, results in a certain temperature rise in this, which immediately entails an increase in the thermal power, and with it an increase in the amount of inflowing tempered return water mixture until an equilibrium state is achieved. The invention thus provides partly an equalization of the water temperature within each water jacket, partly such a distribution of the colder return water on
