Abstract

The invention relates to a chimney stack (110, 210, 310, 410), comprising a closing plate (12) in which openings of an exhaust gas shaft (14) and an air/exhaust gas shaft (16) that are open towards the top, as well as disposed thereinbetween the opening of a fresh air shaft (18) that is open towards the top, are disposed side by side. An exhaust gas discharge neck (20) is provided above the opening of the exhaust gas shaft (14) and an air/exhaust gas discharge neck (22) is provided above the opening of the air/exhaust gas shaft (16), said air/exhaust gas discharge neck having at least one intake opening (24) for supply air close to the closing plate (12). The aim of the invention is to limit the recirculation rate of exhaust gas into the fresh air shaft or into the air inlet shaft of the air/exhaust gas shaft to less than 5 % even under unfavorable wind conditions. To this end, a guiding device (134, 234, 334, 434) is disposed above the opening of the fresh air shaft (18) and guides the exhaust gas discharged from the exhaust gas discharge neck (20) across the opening of the fresh air shaft (18) and across the intake opening (24) of the air/exhaust gas discharge neck (22).

Description

Izum se odnosi na jednu glavu dimnjaka prema uvodnom dijelu patentnog zahtjeva 1. The invention relates to one chimney head according to the introductory part of patent claim 1.

Glava dimnjaka ima jedan kanal za dimne plinove, jedan LAS-kanal i jedan između njih postavljen kanal za svježi zrak sa prema gore otvorenim ulaznim otvorom. The chimney head has one flue gas channel, one LAS channel and one fresh air channel placed between them with an upward opening.

U stručnom žargonu, LAS-kanal označuje jedan zračno-dimni kanal (Luft-Abgas-Schacht), kod kojega je unutar kanala za dovod svježega zraka - uglavnom centrično - postavljen kanal za dimne plinove, tako da se ulazni zrak kreće u suprotnom smjeru u odnosu na dimne plinove duž jednog prstenastog proreza. Ulazni se zrak usisava u podnožju LAS-cijevnog naglavka. U tom je cilju u podnožju LAS-cijevnog naglavka predviđen jedan ili više usisnih otvora, ili je cijelo podnožje izvedeno u vidu rešetke koja se pruža po cijelom obujmu podnožja. Na jedan LAS-kanal priključuju se ložišta velike toplinske moći koja rade neovisno o zraku u prostoriji. In professional jargon, the LAS channel refers to an air-smoke channel (Luft-Abgas-Schacht), where a flue gas channel is placed inside the fresh air supply channel - mostly centrally - so that the incoming air moves in the opposite direction in in relation to flue gases along one annular slit. The incoming air is sucked in at the base of the LAS-pipe nozzle. To this end, one or more suction openings are provided at the base of the LAS-tube header, or the entire base is made in the form of a grid that extends over the entire circumference of the base. One LAS-channel is connected to burners with high thermal power that work independently of the air in the room.

Poseban kanal za svježi zrak postavit će se kada svježi zrak dolazi u vezu sa zrakom u prostoriji, npr. kod otvorenog kamina ili kod ložišta na čvrsto gorivo. A special channel for fresh air will be installed when the fresh air comes into contact with the air in the room, for example near an open fireplace or a solid fuel fireplace.

Iz DE-A 33 42 360 i iz DE 296 21 701 U1 poznata je glava dimnjaka sa jednim kanalom za dimne plinove i jednim kanalom za svježi zrak, pri čemu se dimni plinovi ispuštaju iznad jedne pokrivne ploče dok se dovodni zrak usisava ispod pokrivne ploče i uvodi kanal za svježi zrak. From DE-A 33 42 360 and from DE 296 21 701 U1 a chimney head with one duct for flue gases and one duct for fresh air is known, wherein the flue gases are discharged above a cover plate while the supply air is sucked in under the cover plate and introduces a channel for fresh air.

Slično je rješenje poznato iz DE-U 297 19 924 za glavu jednog dimnjaka koji ima dva, jedan do drugoga postavljena kanala, od kojih je bar jedan od kanala načinjen kao jedan LAS-kanal. Dovodni zrak za LAS-kanal usisava se ispod pokrivne ploče načinjene u obliku prirubnice. A similar solution is known from DE-U 297 19 924 for the head of a chimney which has two channels placed next to each other, of which at least one of the channels is made as one LAS channel. The supply air for the LAS channel is sucked under the cover plate made in the form of a flange.

U DE-G 92 01 176.4 dalje je objavljen jedan uređaj za dovod zraka za sagorijevanje i za odvod dimnih plinova, pri čemu dimni plinovi izlaze iz jednog cijevnog naglavka preko krovnog pokrivača, dok se svježi zrak usisava ispod krovnog pokrivača i kroz LAS-kanal dovodi u ložište. In DE-G 92 01 176.4, a device for supplying air for combustion and for the removal of flue gases is further published, whereby the flue gases exit from a pipe nozzle over the roof cover, while fresh air is sucked under the roof cover and supplied through the LAS channel into the fire pit.

U naprijed navedenim slučajevima izgradnja glave dimnjaka je relativno skupa, bilo zbog toga što je ispod pokrivne ploče potrebna još jedna zaustavna ploča, bilo zbog toga što su na donjoj strani pokrivne ploče postavljeni elementi za usmjeravanje zraka. U obadva navedena slučaja nije pokrivna ploča izrađena jednodijelno sa omotačem dimnjaka. In the aforementioned cases, the construction of the chimney head is relatively expensive, either because another stop plate is needed under the cover plate, or because air directing elements are placed on the underside of the cover plate. In both cases, the cover plate is not made in one piece with the chimney casing.

Zadatak ovog izuma je da se kod naprijed opisane glave dimnjaka i pod nepovoljnim djelovanjem vjetra količina recirkulacije dimnih plinova u kanal za svježi zrak, odnosno u kanal za dovodni zrak jednog LAS-kanala ograniči na manje od 5%. Nepovoljno djelovanje vjetra je kada vjetar puše u pravcu uzdužne osi pokrivne ploče od cijevnog naglavka za odvod dimnih plinova ka LAS-odvodnom cijevnom naglavku. Pored toga, trebalo bi da je po mogućnosti pokrivna ploča načinjena zajedno sa omotačem dimnjaka. The task of this invention is to limit the amount of flue gas recirculation into the fresh air channel, or into the supply air channel of one LAS channel, to less than 5% with the chimney head described above and under unfavorable wind conditions. Unfavorable wind action is when the wind blows in the direction of the longitudinal axis of the cover plate from the flue gas exhaust pipe header to the LAS exhaust pipe header. In addition, if possible, the cover plate should be made together with the chimney casing.

Prema izumu taj je zadatak riješen naznačujućim svojstvima patentnog zahtjeva 1. Pogodna izvođenja prikazana su u zavisnim zahtjevima i tamo su opisana. According to the invention, this task is solved by the indicative features of patent claim 1. Suitable embodiments are shown in the dependent claims and are described there.

Pogodno je što je preko otvora kanala za dovod zraka postavljen jedan usmjerivač tako da dimne plinove koji izlaze iz cijevnog naglavka za odvod dimnih plinova odbacuje naviše i prekida strujanje na jednom prekidnom rubu usmjerivača. It is convenient that one diverter is placed over the opening of the air supply channel, so that the flue gases coming out of the pipe nozzle for the flue gas discharge are rejected upwards and interrupt the flow at one interrupting edge of the diverter.

Ako se ugradi jedan usmjerivač koji nije neposredno u nastavku izlaznih cijevnih naglavaka, već samo prekriva ulazni otvor kanala za ulazni zrak, mogu zbog tzv. Coanda-efekta dimni plinovi naleći na vanjsku stranu usmjerivača i da kod nepovoljnog djelovanja vjetra budu neposredno uvedeni u usisni otvor LAS-dimnjaka. If one router is installed that is not directly in the continuation of the output tube headers, but only covers the inlet opening of the inlet air channel, they can, due to the so-called The Coanda-effect flue gases fall on the outside of the diverter and are directly introduced into the suction opening of the LAS-chimney when the wind is unfavorable.

Da bi se u tom slučaju izbjeglo ulaženje dimnih plinova iz kanala dimnih plinova u usisni otvor kanala za dovod zraka, preporučuje se usmjerivač koji prekriva ulazni otvor kanala za svježi zrak, a koji dimne plinove iz cijevnog naglavka za odvod dimnih plinova odbacuje nagore i ima jedan prekidni rub. In order to avoid the entry of flue gases from the flue gas channel into the intake opening of the air supply channel in this case, a diverter is recommended that covers the inlet opening of the fresh air channel, which rejects the flue gases from the pipe nozzle for the flue gas discharge upwards and has a breaking edge.

Usmjerivač je oblikovan u vidu krova, pri čemu se sljeme krova pruža približno u pravcu poprečne osi pokrivne ploče. Čeone površine usmjerivača otvorene su za prolaz zraka i omogućavaju ulaz svježeg zraka sa strane u prostor ispod pokrivača u čijem je podu načinjen otvor kanala za svježi zrak. Pod čeonom površinom otvorenom za prolazak zraka ne podrazumijeva se samo neka potpuno slobodna čeona površina, već isto tako jedna čeona površina sa postavljenim rešetkama. The diverter is designed in the form of a roof, with the ridge of the roof extending approximately in the direction of the transverse axis of the cover plate. The front surfaces of the router are open for the passage of air and enable the entry of fresh air from the side into the space under the cover, the floor of which has an opening for fresh air channels. Under frontal surface open for the passage of air is meant not only a completely free frontal surface, but also a frontal surface with installed grilles.

Usmjerivač u obliku krova može biti načinjen u vidu kosog krova sa krovnim površinama koje dosežu do tla, tako da se dobiva poprečni presjek u obliku trokuta. The roof-shaped diverter can be made in the form of a sloping roof with roof surfaces that reach the ground, so that a cross-section in the form of a triangle is obtained.

Posebno elegantno djeluje usmjerivač ako ima poprečni presjek u obliku jednakostraničnog trokuta. The router looks especially elegant if it has a cross section in the form of an equilateral triangle.

Na jednoj glavi dimnjaka sa takvim usmjerivačem mjerena je količina recirkuliranja pod raznim uvjetima strujanja. Količina recirkuliranja R u % izračunata je mjerenjem sadržaja CO2 – CCO2 prema jednadžbi: On one chimney head with such a diverter, the amount of recirculation was measured under various flow conditions. The amount of recirculation R in % was calculated by measuring the content of CO2 – CCO2 according to the equation:

CCO2(dovodni zrak) – CCO2(okoline) CCO2 (supply air) – CCO2 (environment)

R [%] = --------------------------------------------- *100 R [%] = -------------------------------------------- *100

CCO2(dimni plinovi) – CCO2(okoline) CCO2 (flue gases) – CCO2 (environment)

Prema analognoj formuli, u kojoj je CCO2(dovodni zrak) zamijenjen sa CCO2(svježi zrak izmjerena je količina recirkuliranja u kanalu za svježi zrak. According to the analogous formula, in which CCO2 (supply air) is replaced by CCO2 (fresh air), the amount of recirculation in the fresh air duct was measured.

Na dijagramu 1 prikazana je količina recirkuliranja u dovodnom zraku LAS-kanala dok je na dijagramu 2 prikazana količina recirkuliranja u svježem zraku u kanalu svježeg zraka, a u ovisnosti o brzini vjetra, od 0 m/s (bez vjetra) do 6 m/s za različite upadne kutove od -30° do +30°. Iz cijevnog naglavka za odvod dimnih plinova izlaze dimni plinovi koji odgovaraju ložištu za čvrsta goriva kapaciteta 20 kW. Pritom izlazi oko 40 m3 dimnih plinova na sat sa sadržajem od 10,2 vol. % CO2. Nastrujavanje se vrši pod nepovoljnim kutom, to jest točno u smjeru od kanala za dimne plinove ka LAS-kanalu. Upadni kut označuje pravac kretanja vjetra u okomitoj ravnini paralelnoj pravcu nastrujavanja, pri čemu struja vjetra ima od koso na dolje prema koso na gore negativnu vrijednost upadnog kuta. Kut nagiba krova iznosi 23°. Diagram 1 shows the amount of recirculation in the supply air of the LAS duct, while diagram 2 shows the amount of recirculation in the fresh air in the fresh air duct, depending on the wind speed, from 0 m/s (no wind) to 6 m/s for different incidence angles from -30° to +30°. Flue gases corresponding to a solid fuel burner with a capacity of 20 kW come out of the flue gas outlet. At the same time, about 40 m3 of flue gases are released per hour with a content of 10.2 vol.% CO2. The flow is done at an unfavorable angle, that is exactly in the direction from the flue gas channel to the LAS channel. The angle of incidence indicates the direction of wind movement in a vertical plane parallel to the direction of flow, where the wind current has a negative value of the angle of incidence from obliquely downwards to obliquely upwards. The angle of inclination of the roof is 23°.

Kao što se iz dijagrama 1 i 2 može vidjeti, i kod jako nepovoljnih dodatnih uvjeta, tj. kod brzine vjetra u opsegu od 2 m/s do 3m/s i kod upadnog kuta odozgo prema dolje od +30° količina recirkuliranja od 5% nije dosegnuta niti za svježi zrak, niti za dovodni zrak. Isto tako ni kod drugih nagiba krova u području od 0° (ravan krov) do 45° (kosi krov) nije izmjerena veća količina recirkuliranja, već je kod povećanja nagiba krova izmjerena manja vrijednost. Kod usporednih mjerenja, pri čemu je preko otvora kanala za svježi zrak postavljen poklopac oblika polucilindra, u dovodnom zraku u LAS-kanalu, pod inače istim uvjetima, izmjerena je količina recirkuliranja veća od 9%. To jasno ukazuje na utjecaj otkidnog ruba na otklanjanju strujanja koje naliježe na pokrivnu ploču zbog tzv. Coanda-efekta. As can be seen from diagrams 1 and 2, even with very unfavorable additional conditions, i.e. with a wind speed in the range of 2 m/s to 3 m/s and with an angle of incidence from top to bottom of +30°, the amount of recirculation of 5% is not reached neither for fresh air, nor for supply air. Similarly, with other roof slopes in the range from 0° (flat roof) to 45° (sloped roof), a larger amount of recirculation was not measured, but a smaller value was measured when the roof slope increased. In comparative measurements, where a half-cylinder cover was placed over the opening of the fresh air channel, in the supply air in the LAS channel, under otherwise identical conditions, the amount of recirculation greater than 9% was measured. This clearly indicates the impact of the tear-off edge on the elimination of the flow that impinges on the cover plate due to the so-called Coanda effect.

Da bi se dobio što je moguće veći prostor ispod usmjerivača, usmjerivač može imati poprečni presjek u obliku jednog peterokuta. In order to get as much space as possible under the router, the router can have a cross-section in the form of a pentagon.

U biti usmjerivač može imati bilo koji poprečni presjek, bitno je samo to da u području vrha ima jedan otkidni rub koji omogućava prekid strujanja. U području podnožja usmjerivača, u blizini pokrivne ploče mogu se napraviti otvori. Pritom se područje podnožja može izvesti u vidu rešetke. Na taj način svježi zrak može strujati u uzdužnom pravcu duž pokrivne ploče i dodatno dospjeti u područje na zavjetrinskoj strani otkidnog ruba. In essence, the router can have any cross-section, the only thing that is important is that it has a tear-off edge in the top area that enables the interruption of the flow. Openings can be made in the area of the base of the router, near the cover plate. At the same time, the area of the base can be made in the form of a grid. In this way, fresh air can flow in the longitudinal direction along the cover plate and additionally reach the area on the leeward side of the tear-off edge.

Na slici 1 shematski je prikazana glava 10 dimnjaka u vodoravnoj projekciji, dok je na slici 2 prikazana u pogledu sa strane. Glava 10 dimnjaka izvedena je sa pokrivnom pločom 12, na kojoj su jedan pored drugoga postavljeni izlazni otvori kanala 14 za dimne plinove i jednog LAS-kanala 16 kao i jedan između njih postavljen, na gore otvoren, ulazni otvor kanala 18 za svježi zrak. Preko otvora kanala 14 za dimne plinove postavljen je jedan konični cijevni naglavak 20, dok je preko otvora LAS-kanala 16 postavljen konični cijevni naglavak 22 LAS-kanala, koji u blizini pokrivne ploče 12 ima usisni otvor 24 koji se u području podnožja po cijelom obujmu u vidu cilindrične rešetke. U LAS-kanalu 16, tj. zračno-dimnom kanalu, unutar kanala 26za dovodni zrak postavljen je jedan LAS-kanal 28 za dimne plinove, tako da za dovodni zrak ostaje slobodan jedan prolaz prstenastog poprečnog presjeka. Pozivnim brojem 30 označena je uzdužna os pokrivne ploče 12, a pozivnim brojem 32 označena je poprečna os pokrivne ploče 12. Figure 1 schematically shows the chimney head 10 in a horizontal projection, while Figure 2 shows it in a side view. The head 10 of the chimney is made with a cover plate 12, on which the outlet openings of the flue gas channel 14 and one LAS-channel 16 are placed next to each other, as well as one of the openings of the channel 18 for fresh air placed between them, open at the top. One conical pipe header 20 is placed over the opening of the flue gas channel 14, while a conical pipe header 22 of the LAS channel is placed over the opening of the LAS channel 16, which near the cover plate 12 has a suction opening 24, which in the area of the base extends over the entire circumference in the form of a cylindrical grid. In the LAS channel 16, i.e. the air-smoke channel, one LAS channel 28 for flue gases is placed inside the channel 26 for the supply air, so that one passage of annular cross-section remains free for the supply air. Reference number 30 indicates the longitudinal axis of the cover plate 12, and reference number 32 indicates the transverse axis of the cover plate 12.

Na slici 1 strelicama β su označeni kutovi pravca vjetra u vodoravnoj ravnini, pri čemu se najnepovoljnija struja vjetra na β = 180° kreće točno u smjeru uzdužne osi 30 od cijevnog naglavka 20 za dimne plinove ka cijevnom naglavku 22 LAS-kanala. In Figure 1, the arrows β indicate the angles of the wind direction in the horizontal plane, whereby the most unfavorable wind current at β = 180° moves exactly in the direction of the longitudinal axis 30 from the pipe header 20 for flue gases to the pipe header 22 of the LAS channel.

Usmjerivač je izveden kao tanka ploča koja se pruža od cijevnog nastavka 20 kanala ispušnih plinova, i prekriva, na nekom razmaku otvor kanala 18 za dovodni zrak kao i usisni otvor 24 LAS-cijevnog naglavka 22. Ploča je šira od kanala 18 dovodnog zraka i ima u području cijevnih naglavaka 20, 22 otvore kroz koje ovi prolaze. Figure 3 shows, in a side view, the first chimney head 110 according to the invention with a plate deflector 134. The deflector is made as a thin plate that extends from the pipe extension 20 of the exhaust gas channel, and covers, at some distance, the opening of the channel 18 for the supply air, as well as the suction opening 24 of the LAS pipe nozzle 22. The plate is wider than the supply air channel 18 and has openings in the area of the pipe nozzles 20, 22 through which these pass.

Na slici 4 prikazana je, u pogledu sa strane, druga glava 210 dimnjaka prema izumu sa usmjerivačem 234 oblika krova formiranim na pokrivnoj ploči 12.
