Description

KURILNI VLOŽEKKURILNI INLOŽEK

Predmet izumaSubject of the invention

Predmet izuma je kurilni vložek kot trdno lesno gorivo, ki je prednostno izdelan iz hlodovine listavcev ali iz lesu podobne snovi, na primer iz stisnjenih in lepljenih lesnih odpadkov in se uporablja kot kurilno sredstvo za ustvarjanje in vzdrževanje toplote v zaprtih kuriščih in na prostem.The subject of the invention is a fuel injection as a solid wood fuel, preferably made of logs of wood or wood-like material, for example from compressed and glued wood waste, and is used as a heating medium for creating and maintaining heat in enclosed furnaces and in the open air.

Tehnični problemTechnical problem

Tehnični problem, ki ga rešuje izum, je nov inovativen izdelek lesnega kurilnega vložka, ki je prednostno izdelan iz odžaganega kosa debla listavca. Možna je tudi njegova izvedba iz lesu podobne snovi, na primer iz stisnjenih in zlepljenih lesnih odpadkov, kot na primer iz žagovine, oblancev, odrezkov in podobno. Njegova izvedba predstavlja povsem novo konstrukcijsko rešitev, ki ni podobna znanim trdnim kurilnim sredstvom, kot so briketi, drva, sekanci, oblanci, peleti, premog in drugi. Bistvena inovativna značilnost kurilnega vložka je v tem, da zaradi svoje izvedbe, oblike in načina prižiga gori od sredine navzven in je temu posledično njegova zunanja površina po celotnem obsegu večina časa gorenja hladna in je zato varnejši za rokovanje in uporabo. Nadalje rešuje problem enostavne priprave za kurjenje in hitrega vžiga, med gorenjem vložka ni potrebno dodajati drugih trdih goriv, skladiščenje vložkov je enostavno in estetsko, za enak čas gorenja je potrebna manjša masa goriva, zaradi boljšega izgorevanja pa se tvori manj dima.The technical problem solved by the invention is a new innovative product of wood fired castings, which is preferably made of a sawn slat-tree piece. It can also be made of wood-like materials, for example, from compressed and glued wood waste, such as sawdust, shavings, chips, and the like. Its design is a completely new construction solution, which is not similar to known solid heating agents, such as briquettes, wood, chips, shavings, pellets, coal and others. The essential innovative feature of the firebox is that due to its performance, shape and mode of ignition it burns from the middle outwards and consequently its outer surface over the entire range of most burning times is cold and is therefore safer for handling and use. Furthermore, it solves the problem of a simple preparation for firing and quick ignition, while it is not necessary to add other solid fuels during the burning of the cartridge, the storage of the cartridges is simple and aesthetic, and for the same burning time a lower mass of fuel is required, and less smoke is formed due to better combustion.

Stanje tehnikeState of the art

Najstarejša znana trdna goriva so drva, premog, sekanci in oblanci, v zadnjem času tudi lesni peleti.The oldest known solid fuels are wood, coal, chips and shavings, and recently also wood pellets.

Iz dostopnih patentnih dokumentov je znanih kar nekaj rešitev trdih goriv.There are quite a few solutions of solid fuels known from the available patent documents.

Po patentnem dokumentu Sl 24020 A je znana energetska kurilna bombica oblike nekoliko višjega valja, ki se sestoji iz lepenkastega plašča napolnjenega s stisnjeno in z mletim voskom prepojeno žagovino in je v celoti odeta z zaščitno folijo proti vlagi. Njena slabost je zlasti v tem, da lepenkast plašč ni odporen na vlago, med stiskanjem lahko poči. Nadalje je njena slabost v tem, da je proizvodnja dokaj zahtevna in dolgotrajna in zato draga.According to the patent document Sl 24020 A, there is a well-known energy barrel forming a slightly higher cylinder, consisting of a cardboard coating filled with pressed and milled wax with a sawdust and completely wrapped with a protective film against moisture. Its disadvantage is, in particular, that the cardboard coat is not moisture-resistant, it can crack during the pressing. Furthermore, its disadvantage is that production is quite demanding and time-consuming and therefore expensive.

Nadalje je po patentnem dokumentu SI/EP 0985723 T1 znano zgoščeno trdno gorivo iz lesa ali lesu podobne snovi v obliki odrezkov ali obliki lesne volne, kateremu je dodan konjski gnoj, celuloza in sečnina. Izdelava tega goriva je zahtevna, dolgotrajna in posledično draga.Further, according to patent document SI / EP 0985723 T1, a known solid fuel from wood or wood-like material is known in the form of chips or wood wool form, to which horse manure, cellulose and urea are added. The production of this fuel is demanding, long-lasting and, consequently, expensive.

Po patentnem dokumentu Sl 21425 A so znani aromatični lesni briketi, ki so izdelani iz kombinacije različnih vrst lesa in aromatičnih delov ene ali več vrst aromatičnih rastlin. Izdelava tega goriva je zahtevna, dolgotrajna in posledično draga.According to the patent document Sl 21425 A, there are aromatic wood briquettes made from a combination of different wood types and aromatic parts of one or more types of aromatic plants. The production of this fuel is demanding, long-lasting and, consequently, expensive.

Predhodno opisane slabosti znanih trdih goriv predstavljajo nerešen tehnični problem. Njihova skupna značilnost je zlasti zahtevna in dolgotrajna proizvodnja, ki je temu posledično zelo draga. Prav tako je njihova priprava za vžig in kurjenje dokaj zahtevna, izgorevanje pa nepopolno.The previously described weaknesses of known solid fuels are an unresolved technical problem. Their common characteristic is particularly demanding and long-lasting production, which is consequently very expensive. Also, their preparation for firing and firing is quite demanding, but the incineration is incomplete.

Opisani tehnični problem bo rešen s kurilnim vložkom po izumu, ki je izvedljiv na vsaj dva načina in sicer kot odžagan del hloda listnatega drevesa ali kot stisnjenec iz zlepljenih lesnih odpadkov, kot so žagovina, oblanci, odrezki in podobni. Zlasti proizvodnja kurilnih vložkov iz hlodovine bo od znanih rešitev enostavnejša in cenejša, zgorevanje boljše, energetski izkoristek pa višji. Konstrukcija kurilnega vložka bo homogena in kompaktna, njegova oblika pa estetsko dopadljiva, kar velja za oba izvedbena primera.The described technical problem will be solved with a heating insert according to the invention, which is feasible in at least two ways, namely as a squeezed part of the log of a log tree or as a clamped pile of wood waste such as sawdust, shavings, chips, and the like. In particular, the production of fuel wood fuel inlays will be simpler and cheaper than the known solutions, while combustion will be better, and energy efficiency will be higher. The construction of the heating cartridge will be homogeneous and compact, and its shape is aesthetically pleasing, which is the case for both embodiments.

Opis izumaDescription of the invention

Rešitev predhodno opisanega tehničnega problema je zasnovana na inovativni izvedbi kurilnega vložka po prijavljenem izumu, ki ga je, oziroma jih je mogoče izdelati na najmanj dva načina. Prednostno izvedbo predstavlja njegova izdelava iz hlodovine, od katere se odžaga ali kako drugače odreže kos hloda oblike nekoliko nižjega valja poljubnih dimenzij, pri čemer je premer kurilnega vložka odvisen od debeline hloda. Pravilo je, da se za izdelavo teh lesnih kurilnih vložkov uporabijo izključno samo debla listavcev, nikakor pa ni priporočljivo za to uporabiti debla iglavcev, ki vsebujejo smolo. Prav tako je priporočljivo, da se za izdelavo uporabijo sušena debla ustreznih listavcev, ki zagotavljajo enostaven prižig, optimalno kurjenje oziroma gorenje in so lahko različnih vonjev ali pa so brez vonja.The solution of the previously described technical problem is based on the innovative embodiment of the heating insert according to the invention claimed, which can be produced in at least two ways. A preferred embodiment is its manufacture from a log of which off or otherwise cuts off a piece of log of the shape of a slightly lower cylinder of any dimensions, wherein the diameter of the heating insert depends on the thickness of the log. The rule is that only wood trunks are used for the production of these wood combustion coils, but it is by no means recommended to use trunks of resin-containing conifers. It is also advisable to use dried trunks of suitable deciduous trees to ensure easy burning, optimum firing or combustion and can be of various odors or odors.

Kot rečeno, je kurilni vložek po prednostni izvedbi odžagan ali kako drugače odrezan kos hloda in je oblike nižjega valja, z vertikalno izvedeno centrično luknjo, ki sega po celi debelini vložka. Iz centrične luknje vodijo radialne notranje zareze poljubnih dolžin, prav tako izvedene skozi celo debelino kurilnega vložka. Po celotnem zunanjem obodu so izvedene zunanje zareze, ki potekajo v obratni smeri proti centrični luknji in so prednostno nekoliko krajše od notranjih zarez, so pa prav tako izvedene skozi celotno debelino kurilnega vložka. Notranje in zunanje zareze si izmenično sledijo v radialnem nizu po celotnem obsegu kurilnega vložka, kar je vidno na njegovih čelnih ploskvah. Zunanji rezi omogočajo sušenje kurilnega vložka, notranji rezi pa omogočajo potreben dotok zraka pri gorenju.As indicated, the combustion cartridge is, according to a preferred embodiment, a sauce or otherwise cut off a piece of log and forms a lower cylinder, with a vertically executed centric hole extending over the entire thickness of the insert. The radial internal notches of arbitrary lengths are guided from the centric hole, also carried out through the entire thickness of the heating element. Throughout the entire outer circumference, the outer incisions are carried out in the opposite direction towards the centric hole and are preferably slightly shorter than the internal notches, but are also carried out throughout the thickness of the heating insert. The inner and outer incisions are alternately followed in a radial sequence over the entire extent of the heating insert, which is visible on its front surfaces. The external cuts allow drying of the heating element, and internal cuts allow the necessary air intake during combustion.

Na eni večji ploskvi so v kurilni vložek izvedeni distančniki, za zagotavljanje potrebnega razmaka med podlago in nanjo položenim kurilnim vložkom. Ploskev z distančniki predstavlja ploskev njegove namestitve. V centrično luknjo se vstavi vžigalni snop iz lesnih palčk, ki služi za zažig kurilnega vložka in, ki prednostno sega do podlage, na kateri vložek leži.In one large area, spacers are made in the combustion insert, to provide the necessary space between the substrate and the filling insert placed on it. The surface with spacers represents the surface of its installation. A centrifugal hole is inserted from the wooden rods, which serves to ignite the heating insert and preferably extends to the base on which the cartridge is lying.

Predhodno je pojasnjeno, da je kurilni vložek prednostno izveden iz odžaganega dela hloda listavca, pri čemer je lahko v drugem izvedbenem primeru kurilni vložek izdelan tudi kot briket, iz zlepljenih in stisnjenih lesnih odpadkov oziroma ostankov, kot so žagovina, odrezki, oblanci in podobnih. Oblika teh stisnjencev je enaka obliki kurilnega vložka iz hlodovine. Za njihovo izdelavo je orodje za stiskanje lesnih odpadkov izvedeno tako, da v celoti določa končno obliko kurilnega vložka, ki po stiskanju ni potreben dodatne obdelave. V prvem izvedbenem primeru osnovno valjčasto obliko kurilnega vložka določa oblika debla, od katerega je bil kos odžagan. Temu sledi še mehanska obdelava odžaganega kosa, kot je vrtanje centrične luknje, žaganje notranjih in zunanjih zarez ter pritrditev distančnikov na eno njegovo večjo ploskev. Seveda je tudi v tem primeru mogoča sprememba osnovne valjčne oblike kurilnega vložka, kar pa zaradi višjih proizvodnih stroškov ni utemeljeno, niti potrebno. V drugem izvedbenem primeru je mogoče stisniti poljubno osnovno obliko kurilnega vložka, ki jo narekuje kalup stiskalnega orodja. Ta je lahko v tem primeru poljubnih pravilnih in nepravilnih geometrijskih oblik. Seveda imajo v tem primeru odločujočo vlogo tudi stroški izdelave takšnega orodja.It is preliminary explained that the combustion cartridge is preferably derived from a squeezed part of the deciduous log, in which case, in the second embodiment, the combustion cartridge can also be produced as briquette, from glued and compressed wood waste or residues such as sawdust, chips, shavings, and the like. The shape of these clamps is the same as the shape of the log-shaped log shell. For their manufacture, the tool for pressing wood waste is designed to completely determine the final shape of the heating insert, which, after pressing, does not require further processing. In the first embodiment, the base cylindrical shape of the heating insert determines the shape of the trunk from which the piece is burned. This is followed by mechanical treatment of a saucepan, such as drilling a centric hole, sawing internal and external notches, and fixing spacers to one of its larger surfaces. Of course, in this case, it is possible to change the basic roll form of the heating input, which is not justified nor necessary due to higher production costs. In the second embodiment, it is possible to compress any basic shape of the heating insert dictated by the mold of the press tool. This may be in any case arbitrary correct and irregular geometric shapes. Of course, in this case, the cost of producing such a tool also plays a decisive role.

Izum temelji na dolgoletnem razvoju optimalne konstrukcije lesnega kurilnega vložka, na uporabi ustreznega materiala ter na metodi njegove izdelave. Pri tem je bil poseben poudarek na osnovnem lesnem materialu, enostavnem prižiganju in optimalnem kurjenju oziroma gorenju, nadalje na dolgotrajnejšem gorenju posameznega vložka brez dodajanja goriva med gorenjem, na optimalnem izgorevanju vložka ter posledično manjšem dimljenju in s tem čistejšim ozračjem. Tudi estetski videz izdelka je bil pri tem v ospredju.The invention is based on the long-term development of an optimum construction of wood fired castings, the use of suitable material and the method of its manufacture. In this regard, a special emphasis was placed on basic wood material, easy ignition and optimal firing or combustion, furthermore on long lasting combustion of a single cartridge without adding fuel during combustion, optimal combustion of the cartridge and, consequently, lower dimming and thus a cleaner atmosphere. Also, the aesthetic appearance of the product was at the forefront.

Kot je predhodno že opisano, predstavlja izum prednostno kolutni, od debla odrezani enovit kos oblike nizkega valja poljubne premera in višine, ki pa morata ustrezati dimenzijam zaprtega ali odprtega kurišča, kar ne velja za kurilne vložke za kurjenje na prostem. Njegova izvedba iz stisnjenih in lepljenih lesnih odpadkov predstavlja temu podrejeno rešitev. Pri eni in drugi izvedbi pa je potrebno upoštevati razpoložljive proizvodne oziroma tehnološke možnosti z vso opremo, ki bodo njihovo izdelavo omogočale. V nadaljevanju bo opisan postopek izdelave ene in druge izvedbe lesnega kurilnega vložka po izumu.As previously described, the invention is preferably a disc rectangular, from a truncated single piece of the shape of a low cylinder of any diameter and height, but which must correspond to the dimensions of the enclosed or open firebox, which is not the case for burning fumes for outdoor fires. Its performance from compressed and glued wood waste represents this subordinate solution. In one and the other embodiment, however, it is necessary to take into account the available production or technological possibilities with all the equipment that will enable their manufacture. In the following, a process for the manufacture of one and the other embodiment of a wood heating element according to the invention will be described.

Pri prvem izvedbenem primeru se od hloda izbranega listavca odžaga kos, ki je prednostno oblike nižjega, poljubno visokega valja. V čelno ploskev odžaganega kosa se skozi celo debelino izvrta centrična luknja poljubnega premera, ki zaradi zagotavljanja dobrega zgorevanja naj ne bo manjši od 3 cm. Po celotnem obsegu se po zunanjem obodu odžaganega kosa izdelajo zunanje vertikalne in radialno potekajoče zareze poljubne debeline, ki so med sabo poljubno oddaljene in ki so poljubne globine v smeri centrične luknje. Sledi izdelava in pritrditev distančnikov na eno večjo ploskev odžaganega kosa. Eno ali obe večji ploskvi kurilnega vložka je mogoče po žaganju tudi površinsko obdelati, za kar pa ni potrebe.In the first embodiment, a piece of the selected deckchar is depressurised, preferably in the form of a lower, arbitrarily high cylinder. A centric hole of any diameter is drilled through the entire thickness of the squeezed piece, which, in order to ensure good combustion, should not be less than 3 cm. The outer perimeter of the squeezed piece produces outer vertical and radially extending slits of any thickness, which are arbitrarily distant from each other and which are arbitrary depths in the direction of the centric hole. The manufacture and mounting of the spacers on one larger surface of the squeezed piece is followed. One or both of the larger surfaces of the heating element can also be surface treated after sawing, but there is no need for it.

Kurilni vložek je primeren za uporabo oziroma kurjenje v zaprtih in odprtih kuriščih in to v zaprtih prostorih in na prostem, na primer notranjih kaminih, vrtnih kaminih in v krušnih pečeh ter na ustrezni podlagi tudi na prostem.The burner cartridge is suitable for use in burning and open fireboxes, indoors and outdoors, for example, internal fireplaces, garden fireplaces and baked ovens, and on an appropriate basis also in the open air.

Predhodno osušeni kurilni vložek v kurišče ali na drugo podlago položimo tako, da stoji na distančnikih, ki omogočajo dotok zraka do mesta gorenja v in ob centrični luknji, v katero pred vžigom vstavimo vžigalni snop lesenih palčk. Nato vžigalni snop na spodnji strani kurilnega vložka prižgemo z vžigalicami ali drugim ustreznim vžigalnim sredstvom. Začetek gorenja je brez dima. S prižigom vžigalnega snopa je postopek za prisotnega kurjača končan. Posamezni kurilni vložek gori okrog 2 do 3 ure, odvisno od njegovih dimenzij, premera in debeline, kakor tudi od tega koliko vložkov je zloženih en na drugega, kar je empirično preizkušeno. V času gorenja kurilnega vložka v kurišče ni potrebno dodajati drv ali drugih goriv.The pre-dried combustion cartridge in the firebox or on another substrate should be positioned on the spacers that allow the air flow to the burning point in and along the centric hole into which the ignition beam of wooden sticks is inserted before the ignition. Then, the ignition beam on the underside of the fuser cartridge is lighted with matches or other suitable incendiary. The start of the burning is without smoke. With the ignition of the firing beam, the procedure for the presence of the frying pan is completed. The individual combustion cartridge burns for about 2 to 3 hours, depending on its dimensions, diameter and thickness, as well as how many cartridges are stacked together, which is empirically tested. No fuel or other fuels should be added during the combustion burning process.

Kot je razvidno iz predhodnega opisa gori kurilni vložek od sredine, oziroma od centrične luknje navzven kar je njegova bistvena značilnost, saj ostala trdna goriva gorijo v obratni smeri. Ker kurilni vložek ne gori po obsegu zunanje stene, je z zunanje strani hladen in ga lahko med gorenjem ročno premikamo.As can be seen from the previous description, a burning cartridge burns from the center, or from a centric hole outwards, which is its essential characteristic, since the remaining solid fuels are burning in the opposite direction. Since the combustion cartridge does not burn on the external wall, it is cold from the outside and can be manually moved during burning.

Notranje in zunanje zareze omogočajo na eni strani sušenje kurilnega vložka, na drugi strani pa boljše izgorevanje s tem boljši izkoristek in manj dima. S ciljem natančnejšega opisa in prikaza izvedbe kurilnega vložka po prijavljenem izumu, bo le-ta v nadaljevanju opisan na osnovi obeh predhodno navedenih prednostnih izvedbenih primerov ter predstavljen s pomočjo slik, ki prikazujejo sl. 1 kurilni vložek po izumu, v aksonometrični projekciji sl. 2 enako, kot v sl. 1, samo v tlorisuInternal and external notches allow drying of the combustion cartridge on the one hand, and on the other hand, better combustion with this better efficiency and less smoke. In order to provide a more detailed description and demonstration of the performance of the heating insert according to the invention, the description will be described hereinafter on the basis of the aforementioned preferred embodiments, and is illustrated by means of the figures shown in FIG. 1 combustion cartridge according to the invention, in the axonometric projection of Fig. 2 is the same as in FIG. 1, only in the ground plan

Kurilni vložek 1 po izumu je prednostno oblike nekoliko nižjega valja poljubnega premera in debeline, ki ustreza dimenzijam kurišča. V nekem drugem izvedbenem primeru je lahko njegovo telo tudi drugačni pravilnih ali nepravilnih geometrijskih oblik. Skozi njega je po celotni debelini izvedena vertikalna centrična luknja 2 prednostno okroglega preseka, ki je lahko v nekem drugem izvedbenem primeru tudi drugačnega preseka, pravilnega ali nepravilnega geometrijskega lika. Na eni večji ploskvi kurilnega vložka 1 so prednostno izvedeni trije distančniki 5, ki so hkrati njegove nosilne nogice. V nekem drugem izvedbenem primeru je lahko distančnikov 5 tudi več, oziroma je lahko kurilni vložek 1 izveden tudi brez njih.The burner cartridge 1 according to the invention is preferably a shape of a slightly lower cylinder of arbitrary diameter and thickness corresponding to the dimensions of the firebox. In another embodiment, the body may also be of different or irregular geometric shapes. Through it, a vertical centric hole 2 of a preferably circular cross-section is implemented along the entire thickness, which may also be in a different embodiment of a different cross section, a regular or irregular geometric figure. Preferably three spacers 5, which are at the same time its supporting legs, are preferably made on one larger surface of the combustion cartridge 1. In another embodiment, spacers 5 may also be larger, or the combustion cartridge 1 may also be made without them.

Iz centrične luknje 2 so v smeri proti zunanjemu plašču kurilnega vložka 1 radialno izvedene notranje zareze 4 poljubnih dolžin in širin, ki se končajo nekoliko pred robom zunanjega plašča in so od njega poljubno oddaljene. So pa notranje zareze 4 praviloma izvedene po celi debelini kurilnega vložka 1 in so ena od druge poljubno oddaljene.From the centric hole 2, the inner sheaths 4 of the lengths and the widths ending slightly outside the edge of the outer jacket are arbitrarily removed from the outer jacket of the combustion insert 1. However, the internal notches 4 are, as a rule, implemented along the entire thickness of the heating element 1 and are arbitrarily distant from each other.

Po celotnem obsegu zunanjega plašča kurilnega vložka 1 so v smeri proti centrični luknji 2 izvedene zunanje zareze 3 poljubnih dolžin in širin, ki so prednostno pozicionirane med nasprotne notranje zareze 4. Zunanje zareze 3 so nekoliko krajše od notranjih zarez 4 in so prav tako izvedene po celi debelini kurilnega vložka 1 in so ena od druge poljubno oddaljene.Throughout the entire circumference of the outer jacket of the combustion cartridge 1, the outer incisions 3 optional lengths and widths, preferably positioned between the opposite internal notches 4, are directed towards the centric hole 2. The outer incisions 3 are slightly shorter than the inner notches 4 and are also carried out after the entire thickness of the combustion cartridge 1 and are arbitrarily distant from one another.

Notranje zareze 4 so radialno usmerjene od centrične luknje 2 proti zunanjemu plašču kurilnega vložka 1, dočim so zunanje zareze 3 usmerjene v nasprotni smeri tako, da si v nizu izmenično sledijo po celem obsegu kurilnega vložka 1.The inner notches 4 are radially directed from the centric hole 2 towards the outer jacket of the combustion cartridge 1, whereas the outer incisions 3 are directed in the opposite direction so that they follow alternately in the array throughout the combustion cartridge 1.

Kurilni vložki 1 so prednostno lesne izvedbe.The burning inserts 1 are preferably woodworking.

Prednostni izvedbeni primer predstavlja izdelava kurilnega vložka iz hlodovine listavcev tako, da se od hloda odžaga ali kako drugače odreže kos oblike nižjega valja, v katerega se v nadaljevanju izdela centrična luknja 2, nato notranje zareze 4 in zunanje zareze 3, na koncu pa se dodajo še distančniki 5.A preferred embodiment is the production of a frying pan from the logs of the deciduous trees by removing or otherwise cutting off the shape of the lower cylinder form into which the centric hole 2, the inner notches 4 and the outer incisions 3 are then produced, and finally added still spacers 5.

Naslednjo izvedbo predstavlja izdelava kurilnih vložkov 1 iz zlepljenih in stisnjenih lesnih odpadkov oziroma ostankov, ki se v končni izdelek oblikujejo v zato namenjenem orodju. Na ta način izdelani kurilni vložki 1 so lahko poljubnih pravilnih in nepravilnih geometrijskih oblik in so lahko poljubnih dimenzij.The next embodiment is the production of combustion inserts 1 from glued and compressed wood waste or residues, which are formed into the finished product in the intended tool. In this way, the combustion inserts 1 can be of any kind of correct and irregular geometric shapes and may be of any dimensions.

Za zažig kurilnega vložka 1 je namenjen vžigalni snop 6 iz lesnih palčk, vstavljen v centrično luknjo 2.To ignite the combustion cartridge 1, a light beam ignition beam 6 is inserted into the centric hole 2.

Kurilni vložek 1 je uporaben za kurjenje in ogrevanje v zaprtih in odprtih kuriščih in to v zaprtih prostorih, kot tudi na prostem.The burner cartridge 1 is useful for burning and heating in indoor and outdoor fireboxes, both indoors and outdoors.
