    Brief indication: Channel section for placement in a flue for a fireplace, as well as a fireplace provided with such a channel section.
    DESCRIPTION
    The invention relates to a channel section for placement in a flue, which flue is adapted for connection to the combustion space of a fireplace, in particular a gas fireplace, the flue being composed of a flue gas discharge channel connecting to the combustion space for the purpose of operating during the fireplace - discharging combustion flue gases from the combustion space, as well as a combustion air supply channel concentrically and in heat-exchanging contact with the flue gas discharge channel for feeding the combustion air into the combustion space elsewhere during the operation of the fireplace.
    Gas fires are increasingly being built into houses nowadays. In order to guarantee the correct and safe functioning of the fireplace in, for example, the home, safety regulations have been drawn up that require a gas check of the flue to which the gas fire is connected. In particular, it must be checked annually whether the supply of combustion gases and, in particular, the oxygen content into the combustion space is to be checked. Insufficient supply of oxygen into the combustion space can lead to incomplete combustion, whereby hazardous combustion flue gases such as carbon monoxide can be released.
    The object of the present invention is therefore to provide a solution with which the quality of the combustion air to the combustion space can easily be checked in a simple non-destructive manner with an already installed fire.
    According to the invention, the channel section is characterized in that it comprises a sampling line in gas communication with the combustion air supply channel for extracting a sample of combustion air from the combustion air supply channel. This makes it possible to easily analyze the gas conditions in the combustion air supply duct and in particular the oxygen content of the combustion air to be supplied to the combustion space.
    In a specific embodiment, the channel section is further characterized in that the sampling line is arranged around the entire circumference of the combustion air supply channel. Because combustion air is thus extracted from the full circumferential volume of the combustion air supply channel for sampling, a more accurate measurement of the oxygen content in the combustion air is thus obtained.
    Extracting a sample of combustion air from the combustion air supply channel from the full circumferential volume can be improved according to the invention if the sampling line is in gas communication with the combustion air supply channel at several locations.
    In a first embodiment according to the invention, the sampling line is formed as a circumferential flanged edge arranged in the wall of the combustion air supply duct. Such a seamed edge can be arranged in the wall in a single operation, wherein the seamed edge does not adversely affect the functionality (in particular the gas density) of the combustion air supply duct.
    According to a first embodiment, the circumferential seamed edge can be arranged inwardly in the wall of the combustion air supply channel and in a second embodiment can be arranged outwardly in the wall of the combustion air supply channel.
    In this case, the circumferential seamed edge can further be closed with the aid of a plate part arranged against the wall of the combustion air supply duct. A circular sampling line or space is hereby realized, which is well sealed and therefore has no gas leakage outside the combustion air supply duct.
    The plate part can herein be provided with a plurality of openings for withdrawing a sample of combustion air over the entire circumference of the combustion air supply duct.
    According to the invention, for an improved method of sampling a sample of combustion air, the sampling channel is provided with a protruding connecting line for connecting a sampling device for sampling combustion air.
    The invention also relates to a fireplace, in particular a gas fireplace, at least comprising a connection for a flue, which is connected to the combustion room, and for a flue provided with a channel section according to the invention.
    In a functional embodiment, the channel section is placed between the connection and the flue.
    The invention will now be explained in more detail with reference to a drawing, which drawing successively shows in:
    Figure 1 shows a schematic embodiment of a fireplace suitable for a channel section according to the invention;
    Figure 2 shows an embodiment of a channel section according to the invention;
    Figure 3 is a view of an embodiment of a channel section according to the invention.
    For a better understanding of the invention, the corresponding parts shown in the various figures are indicated in the following figure description with identical reference numerals.
    Figure 1 shows an embodiment of a fireplace according to the prior art. The fireplace 10 is usually built into a chimney (not shown) and is provided with a housing 11, which can be closed at the front by a mostly transparent panel 12, in particular a glass panel. This glass panel 12 closes the front open side of the combustion space 13 of the hearth 10.
    The hearth 10 has a connection flange 14 for connection to a flue not shown. Such a smoke channel is made up of two pipe parts placed concentrically around each other. In particular, the inner concentric tube part has the function of a flue gas discharge channel connecting to the combustion space 13 for discharging combustion flue gases from the combustion space 13 during operation of the fireplace 10. The outer pipe part, which is arranged concentrically around the flue gas discharge channel, functions as combustion air supply channel for supplying combustion air into the combustion space 13 during operation of the fireplace 13.
    In order to improve the combustion process in the combustion space 13, the outer combustion air supply channel is in heat-exchanging contact with the inner flue gas discharge channel, so that the combustion air, which is often supplied from the outside and therefore colder from the outside, is preheated into the combustion space through the discharged combustion flue gases. This prevents a cold fall due to the cold combustion air in the combustion space, whereby the combustion process is adversely affected.
    In Figure 2, reference numeral 20 shows an embodiment of a channel section according to the invention. The channel section 20 has a connecting flange 21 for placement on a wall part 11a (see figure 1) of the hearth 10.
    The channel section 20 then connects to the channel connection 14 which leads to the combustion chamber 13 of the hearth 10.
    The channel section 20 is made up of an outer tube part 22 as well as an inner tube part 27 (see figure 1), which two tube parts are arranged concentrically around each other.
    Thus, the inner tube part 27 connects to the inner tube part of the flue, which functions as a discharge channel of the combustion flue gases from the combustion chamber 13. The outer tube part of the flue and, accordingly, the outer tube part 22 of the channel section 20 forms a concentric around the inner tube part supply channel formed from the flue for supplying combustion air (oxygen) into the combustion space 13.
    The combustion air supply channel 22 arranged concentrically around the flue gas discharge channel 27 thereby comes into heat-exchanging contact with the flue gas discharge channel 27 for the purpose of partially heating the supplied combustion air, which combustion air is usually supplied to the combustion space 13 from outside and therefore with a low temperature.
    According to the invention, the channel section 20 is provided with a sampling space 23 for extracting a sample combustion air from the combustion air supply channel 22. This makes it possible to easily sample the quality of the combustion air and, in particular, the oxygen content during regular checks.
    This can thus be done in a simple repeatable manner without the structure in which the fireplace is built in (for example the fireplace) having to be dismantled temporarily.
    As shown in figures 2 and 3, the sampling space 23 is arranged around the entire circumference of the combustion air supply duct 22. Thus, combustion air is extracted from the full peripheral volume of the combustion air supply channel 22 for sampling, which yields a more reliable sample combustion air and results in a more accurate measurement of the oxygen content.
    As is clearly shown in Fig. 3, the sampling space 23 is formed by a flanged edge 22a arranged in the wall of the combustion air supply channel 22, which flared edge 22a extends over the entire circumference of the combustion air supply channel 22. In this embodiment, the seamed edge 22a is directed outwards, and is therefore formed by the cylinder wall of the combustion air supply channel 22. Thus, the combustion air supply channel remains completely closed on the outside, which prevents the risk of leaks from the outside.
    The circular sampling space formed by the seamed edge 22a is closed on the inside of the combustion air supply channel 22 by a plate part 26 which is provided with a plurality of openings 26a which enable a gas connection between the sampling space 23 and the internal volume of the combustion air supply channel 22. Because the openings 26a are arranged over the entire circumference of the plate part 26, thus over the complete circumferential volume (which is formed by the space between the wall parts 22 and 27) of the combustion air supply channel 22, combustion air is extracted from the combustion air supply channel so that the sample of combustion air which enters the the sampling space 23 is similar in composition to the combustion air in the combustion air supply duct, which guarantees a reliable and truthful measurement of the oxygen content and therefore a good indication of the combustion effect of the relevant h nature.
    In another embodiment (not shown), the seamed edge 22a is arranged inwardly in the wall of the combustion air supply channel 22 and the inwardly directed seamed edge is closed off on the outside of the combustion air supply channel 22 with a plate part. Any openings which can be compared with openings 26a in Fig. 3 are then arranged in the inward facing seam 22a.
    Although this embodiment has the advantage that the channel section 20 does not widen locally and is easier to place in a tight chimney in terms of built-in dimensions, this embodiment is less attractive in that the plate part provided on the outside of the combustion air supply duct 22 entails a possible risk of leakage.
    The sampling space 23 is provided with a connecting line part 24, which is suitable for connecting a sampling device for sampling combustion air. The connecting line part 24 can be provided with the aid of a rigid or flexible line part 24 "which can be concealed along the fireplace construction in the direction of a position or location that can be easily accessed for sampling purposes. The pipe part 24 "is provided at its end with a coupling 24" to which a sampling device can be connected. Optionally, the housing 11 of the hearth 10 can be provided with such a coupling 24 °, to which the pipe part 24 'connects.
