Description

Uppfinnare: F Sperlich Prioritet begtird frail den 30 juni 1960 (Forbundsrepubliken Tyskland) Uppfinningen avser en uppvarmningsanordning for med flytande bransle matad munstycksbrannare med en ringformig tryckforangare, som omsluter en central kanal och omgives av en pa visst avstand anordnad mantel, vilken tillsanunans med tryckforangarens yttre vagg bildar en ringformig kanal, varvid en uppsamlingsanordning for den branslemangd som skall uppvarmas fir anbragt framfOr tryckfOrangaren. Inventor: F Sperlich Priority dated 30 June 1960 (Federal Republic of Germany) The invention relates to a heating device for a nozzle fired with a liquid fuel with an annular pressure evaporator, which encloses a central channel and is surrounded by a jacket arranged at a certain distance. The cradle forms an annular channel, a collecting device for the amount of fuel to be heated being placed in front of the pressure evaporator.

Hittills har for namnda brannartyp mestadels anvants uppvarmningsanordningar, vid vilka uppsamlingsanordningen for branslemangden, som skall uppvarmas, bestar av ett lagre an tryckforangaren placerat karl. Vid anvandning av tragflytande branslen sasom t. ex. eldningsolj a, erhalles dock harvid mycket langa uppyarmningstider, yarfor mestadels extra uppvarmningsanordningar, sasom uppvarmningsbrannare maste anvandas. Hitherto, for the said type of burner, heating devices have mostly been used, in which the collecting device for the amount of fuel to be heated consists of a bearing placed on the pressure evaporator. When using the floating industry as e.g. heating oil a, however, is obtained with very long heating times, yarfor mostly extra heating devices, such as heating burners must be used.

FOr fOrbattring av dessa kanda uppvarmningsanordningar har aven tidigare foreslagits anvandning av en atminstone delvis melIan munstycke och tryckforangaren placerad veke, vilken är anordnad i ett samtidigt som vekhallare utformat karl. Harigenom kan visserligen uppvarmningstiden avsevart forkortas, sâ att nagon tillsatsbrannare icke erfordras, men f8r brannarens igangsattning sarskilt vid laga temperaturer behovs likval fortfarande relativt lang tid, varfor en obegransad anvandning av namnda brannartyp hittills icke varit mOjlig. For the improvement of these known heating devices, it has also previously been proposed to use a wick placed at least partially between the nozzle and the pressure evaporator, which is arranged in a vessel designed at the same time as the wick holder. As a result, the heating time can be considerably shortened, so that no additional burner is required, but for the burner to start especially at low temperatures, a still long time is still required, for which an unlimited use of the said burner type has not been possible so far.

Med uppfinningen astadkommes nu en uppvarmningsanordning med vilken tryckforangaren kan uppvarmas till driftstemperaturen pa I forhallande till kanda anordningar avsevart kortare lid. The invention now provides a heating device with which the pressure evaporator can be heated to the operating temperature in relation to known devices with a correspondingly shorter lead.

Detta syfte uppnas enligt uppfinningen genom ett efter uppvarmningsperioden borttagbart framfOr tryckforangarens centrala kanal anordnat tackelement, som tacker kanalens inloppsOppning till minst 60 %, foretradesvis minst 80 %. This object is achieved according to the invention by a tack element arranged in front of the central channel of the pressure evaporator which can be removed after the heating period, which tackles the inlet opening of the channel to at least 60%, preferably at least 80%.

En ytterligare avsevard fOrkortning av uppvarraningstiden erhaller man, om man i tryckforangarens centrala kanal anordnar en Mrformig ledkropp for la.gan, sa att en ringformig kanal bildas mellan dess yttervagg och fOrangarens vagg, varvid man under uppvarmningsperioden endast tacker inloppsoppningen i den ringformiga ledkroppen for ratan. Forbranningsgaserna frau det i forangaren uppvarmda branslet kunna pa detta satt na fram till aven den vagg i forangaren som bildar den centrala kanalen, utan att a andra sidan mangden av forbranningsgaser, som till f8ljd av tackelementet strommar genom den ringformiga kanalen mellan manteln och tryckforangaren, reduceras i alltfOr hOg grad. A further considerable shortening of the heating time is obtained if, in the central channel of the pressure evaporator, a Mr-shaped hinge body is arranged for the bearing, so that an annular channel is formed between its outer wall and the cradle of the evaporator, during the heating period only the inlet opening in the annular hinge body . The combustion gases from the fuel heated in the evaporator can in this way also reach the cradle in the evaporator which forms the central channel, without on the other hand the amount of combustion gases flowing through the annular channel between the jacket and the pressure evaporator due to the tack element. to a very high degree.

I en fordelaktig utforingsform av uppfinningen utformar man tackelementet som vek- 2 element, dvs. som veke eller vekhallare. Enklast anvandes harvid vekelementet tillsammans med ett stavformigt hallarelement som Junta. In an advantageous embodiment of the invention, the tack element is designed as a folding element, i.e. as wick or wickhaler. The easiest way is to use the folding element together with a rod-shaped holding element such as Junta.

Det är harvid lampligt att det foretradesvis av asbest besthende vekmaterialet under uppvarmningsperioden kommer i beroring med kanten pa inloppsoppningen ph den centrala fOrangningskanalen respektive den rorformiga ledkroppen for lagan, da harigenom i vane fall en god tatning astadkommes utan sarskilda centreringsanordningar, vilket icke obetydligt paverkar uppvarmningstiden. It is then appropriate that the preferably asbestos-containing wick material during the heating period comes into contact with the edge of the inlet opening of the central vapor channel and the tubular hinge body of the layer, as this usually results in a good seal without special centering devices, which does not obstruct.

AnvOndningen av ett i oth for sig kant, lagre an forangaren anordnat karl, som är dimensionerat sa, att projektionen av en tankt forbindningslinje fra'n munstycket och tryckforangaren faller mom detsamma rekommenderas sarskilt i forbindelse med foremalet for uppfinningen, emedan tackelementets verkan vid forbranning av branslet i detta karl är sOrskilt stor under uppvarmningsperioden och dessutom vid anvandning av en tillsatsveke det Iran denna neddroppande branslet uppfangas av kdrlet. The use of a separate edge bearing arranged on the evaporator, which is dimensioned so that the projection of a tank connection line from the nozzle and the pressure evaporator falls accordingly, is especially recommended in connection with the object of the invention, since the action of the tack element in burning the industry in this tank is particularly large during the heating period and also when using an additive wick in Iran this dripping industry is captured by the boiler.

Bifogade ritning askadliggar ett utforingsexempel av uppvarmningsanordningen enligt uppfinningen, vilket narmare beskrives harnedan, varvid ytterligare kannetecken for uppfinningen angivas. Fig. 1 visar en munstycksbrannare med en som Junta utformad tackanordning; fig. 2 visar den i fig. 1 askh.dliggjorda luntan, delvis i snitt och fig. 3 visar en annan avenledes som lunta utformad tiickanordning. The accompanying drawing illustrates an exemplary embodiment of the heating device according to the invention, which is described in more detail below, in which further features of the invention are given. Fig. 1 shows a nozzle burner with a filling device designed as a Junta; Fig. 2 shows the cord made of Fig. 1, partly in section, and Fig. 3 shows another rope device designed in the form of a cord.

Den i fig. 1 visade ringformiga tryekforangaren 1 tillfores bransle Over en tilloppsledning 2, vilken Over en regleringsventil 3 ar forbunden med en frau en icke visad branslebehallare kommande ledning 4. The annular pressure evaporator 1 shown in Fig. 1 is supplied with fuel via an inlet line 2, which via a control valve 3 is connected to a line 4 coming from a fuel container (not shown).

I en central kanal 5 i tryekfOrangaren 1 är en rorformig ledkropp 6 for Fagan anordnad, vars vagg 7 tillsammans med en inre vagg 8 I tryckforangaren 1 bildar en ringformig kanal 9, vilken i naturlig storlek foretradesvis har en bredd av hogst 3 mm. Vidare bildas ytterligare en ringformig kanal 12 av en yttre vagg 10 i tryckforangaren 1 och en pa visst avstand frau denna anordnad mantel 11. In a central channel 5 in the pressure evaporator 1 a tubular hinge body 6 for the phage is arranged, whose cradle 7 together with an inner cradle 8 in the pressure evaporator 1 forms an annular channel 9, which in natural size preferably has a width of at most 3 mm. Furthermore, a further annular channel 12 is formed by an outer cradle 10 in the pressure evaporator 1 and a jacket 11 arranged at a certain distance therefrom.

Inloppsoppningen for den r8rformiga ledkroppen 6 tackes av ett tdckelement 13, vilket tillsammans med en veke 14 och ett larelement 15 bildar en lunta sasom visas i tvarsnitt enligt fig. 2. Hallarelementet 15 be-star darvid av ett rar, genom vilket veken 14 kan drankas med bransle. The inlet opening of the tubular hinge body 6 is thanked by a cover element 13, which together with a wick 14 and a clay element 15 forms a cord as shown in cross section according to Fig. 2. The holder element 15 then consists of a tube through which the wick 14 can be drunk. with industry.

En fordelaktig utforingsform av tackelementet askadliggores i fig. 3, som visar en lunta, i vilken vekens material 16 sammanMlles med en ring 17, varvid den sidan, som skall tryckas mot inloppsappningen i farangaren resp. i utforingsexemplet enligt fig. 1 i den rOrformiga ledkroppen 6 avenledes bestar av vekmaterial, varfor en avtatning av denna appning är majlig aven dä luntan Mlles i snett lage. An advantageous embodiment of the tack element is damaged in Fig. 3, which shows a cord, in which the material 16 of the wick is assembled with a ring 17, the side to be pressed against the inlet opening in the faranger resp. in the exemplary embodiment according to Fig. 1 in the tubular articulated body 6, it is thus also composed of wick material, for which reason a reduction of this opening is possible even when the wire Mlles is inclined.

Tackelementet 13 kan givetvis Oven vara svangbart anbragt t. ex. vid tryckforangaren 1, tilloppsledningen 1 eller ledkroppen 6 for lhgan. The roof element 13 can of course also be pivotally arranged, e.g. at the pressure evaporator 1, the supply line 1 or the hinge body 6 for the body.

Da tryckforangaren 1 uppnatt drifttemperatur, maste dock, am tackanordningen är utformad som veke, denna Ater avlagsnas, for att veken icke skall bli kvar direkt i centrum av den fran det genom tryckledningen 19 matade munstycket utsprutade angstrhlen. When the pressure evaporator 1 has reached operating temperature, however, if the filling device is designed as a wick, this return must be removed so that the wick does not remain directly in the center of the nozzle ejected from the nozzle fed through the pressure line 19.

Sasom redan namnts begransas uppfinningen icke till det askadliggjorda utforingsexemplet utan kan modifieras och kompletteras pa olika salt utan att uppfinningsramen Overskrides. As already mentioned, the invention is not limited to the ashless embodiment but can be modified and supplemented on various salts without exceeding the scope of the invention.
