Abstract
Description
- The present invention is for a chimney which may be used with one or more fireplaces or hearths both at new installations and rebuilding.
- Chimneys for fireplaces or hearths which are intend to generate heat primarily for heating and hot water generation have traditionally been built of brick. The chimney stack then mainly has its extension inside through the building. There have also been developed chimneys having chimney flues made from steel. Due to the high temperatures of the flue gases these ways of building strictly regulated and at known constructions it is required that the the chimneys or flues are built into special shafts in the building. This takes up a lot of space and means that the building of the chimney must be at the site. Further requirements then are that the shaft must be sealed so that the intrusion of oxygen to possibly leaking out flue gases is prevented as the gases may be explosive. Conventional outer jackets made from metal or concrete, pumice or the like has joints and are not satisfactorily sealed.
- The object of the present invention is a chimney which has flue flues made from steel and so made that it may be installed without a shaft. This means that a chimney may be installed inside or adjacent all kinds of building constructions and building materials. It is also an object that is shall be possible to assemble the chimney in whole in a factory for direct installation at its place in the building. It is further an object to achieve a chimney of low weight so that it may be put on the existing framing of joists without any reinforcement thereof. The chimney according to the invention och embodiments thereof has the characterising features which are mentioned in the claims.
- In order that the chimney may be installed without a shaft the temperature at its outer surface may not at any moment or at any spot be above a highest allowed temperature. The chimney according to the present invention thus has a smoke flue which is surrounded by an inner jacket and an outer jacket, preferably made from steel. The space between the outer jacket and the smoke flue is filled with insulating material which is of granular or powder form or other form which allows flowing of the material. The chimney is so designed that no empty pockets may occur within the insulating material neither at manufacture nor at use. For this aim the inner jacket is so adapted that its has regular discontinuities through which the insulating material may pass between the two sides of the inner jacket, where the motions of the insulating material may be caused by expansion and retraction of the smoke flue due to the always occurring changes of temperature. Preferably the smoke flue is made from corrugated steel. A reservoir or compensation possibility for insulating material is arranged at the top section of the chimney.
- The invention will below be described more in detail with reference to the embodiment which is shown in the enclosed figures.
- Figure 1 is a horizontal cross section through a vertical section of a chimney.
- Figure 2 is a vertical cross section through the section of the chimney.
- Figure 3 is a vertical cross section through a partially deflecting chimney.
- The chimney according to the invention comprises a smoke flue 1 which is surrounded by an
inner jacket 2 and anouter jacket 3. Theinner jacket flue 2 is connected to theouter jacket 3 by means ofmembers 4 whereas the smoke flue 1 is freely arranged inside the inner jacket. The three tubes are mainly concentric but deviations occur at chimneys having deflections. The space between theouter jacket 3 and the smoke flue 1 is totally filled with insulating material. - The smoke flue 1 is preferably made from corrugated, spirally wound steel which forms a flexible tube. Goods and dimensions are selected considering the application where the selection of fuel and the number of hearths are essential parameters. The smoke flue tube is continuous without any discontinuities or junctions except for possible branching where smoke flues from several hearths are joined. The
outer jacket 3 is divided into sections which are joined by sleeves to a continuous outer jacket. Also theinner jacket 2 is divided into sections. These are fixedly mounted to the outer jacket by means ofmembers 4 so that there is a open slot between each of the inner jacket sections - Chimneys according to the invention may be made with some sections deflecting from the vertical line for example as shown in figure 3. The sections of the outer jacket are connected by
sleeves 7 and the section of the inner jacket in a corresponding way byjoint guides 8. There aremembers 4 as required between the outer and inner jacket and that section of the inner jacket which deviates from the vertical line is preferably without joint slots. - The
insulating material 5 is selected so that it will fill up all of the accessible spce between the smoke flue and outer jacket. Thus the material ought to be powdered or granular and be flowing. At manufacture and installation of a chimney according to the invention the individual sections of the outer and inner jacket are first joined together where after jacket sections are put together to a chimney jacket. The flexible flue is then inserted into the jacket and connected to the hearth in known manner. After this the insulating material is filled in between the flue and the outer jacket by way of pouring into thevolume 5 from the top of the chimney. The slots between the sections of the inner jacket will then secure that all accessible space is filled with insulating material as this may flow both vertically downwards into accessible volumes and between the sides of the inner jacket by passing through the slots. - When in use the chimney is exposed to great variations of temperature which cause expansion and contraction of the flue and the jackets, causing that the insulating material is deformed and very slowly disintegrates into small parts. The disintegration and the movements cause a gradual compacting of the insulating material. Additional insulating material may continuously be added from the storage container and the upwards and downwards movements of the corrugated surface, which are caused by the changes of temperature, provide a feeding function which secures that fresh insulating material is continuously supplied so that no empty pockets occur in the insulation. At the top of the chimney there are means for compensation of the reduced volume of insulating material. Primarily this comprises a ring of rockwool or the like flexible or elastic insulating material which fills up the entire space between the flue and the outer jacket At the assembly the height of the ring is compressed and it then expands downwards as the volume of the granular insulating material is reduced. Another alternative is to arrange at the top of the chimney a container which is in open connection with the
insulation volume 5. The container, which for example may be made as a surrounding funnel or be arranged at one side of the top of the chimney, is filled up with a supply of insulating material which gradually flows down into the insulation space as the existing material there is reduced in volume. The container is filled up with insulating material when required. - As it is secured with a chimney according to the invention that there always is sufficient amount of insulating material between the outer jacket and the flue so that the outside temperature of the outer jacket always is below the highest temperature allowed the chimney may be installed without a surrounding shaft. It may wholly or partially be prefabricated at a factory, which is preferred in case of new buildings, while by rebuilding and replacement of old chimneys it is also possible to manufacture the jacket as sections of desired length. The are put in position and the flue is then inserted and insulating material is filled in. Preferably the outer jacket is made as sections which are that much longer than the sections of the inner jacket as corresponds to the size of the desired slots between the sections of the inner jacket. At the assembly it is preferred to make use of joint sleeves with insulating material so that a sealed outer jacket is obtained.
- Chimney according to the invention also brings further advantages with it. The low-weight and steady design means that the chimney may be raised on existing framing of joists without reinforcements and the structure is self-supporting also at sidewise deflecting design. Compared to previously known designs also the problem with noise that is generated at the changes of length of the material is reduced. Control and inspection is made easier as the installation is well visible and all joints may be positioned so that they are readily available for inspection. The chimney may be adapted to various conditions of use and more than one flue may be installed in one and the same jacket. At change of hearth or method of heating, e. g. changing oil to logs, the flue may be exchanged so that the best condition also are obtained.
- The chimney according to the invention further has the important advantage that there is smaller decrease of the temperature of the flue gas than is the case with hereto known chimney designs for corresponding applications and uses. The reduced decrease of the drop of the temperature may be utilised either to to lower the temperature of the output gas from the hearth and so achieve a higher efficiency thereof or to achieve a higher temperature of the flue gases out from the chimney. It is a further advantage that at start up the initially cold chimney quickly reaches a steady state temperature both of the flue and the outer jacket.
- Within the frame of the inventive idea there are also other possible embodiments besides what is apparent from the examples above. Both the flue and the surrounding jacket may have cross sections which are different from circular, primarily elliptic or rectangular shapes are possible. At certain embodiments with a straight chimney or a chimney which only has a small sideways deviation the flue may be a smooth tube.
