Definitions

  • the invention relates to an exhaust device for a burner heater in a mobile room.
  • the invention relates to a safety device for the operation of heaters or other devices with gas or liquid fuel burners, which are used in living or passenger spaces (interiors, mobile spaces) of mobile devices.
  • living or passenger spaces internals, mobile spaces
  • mobile spaces can be found especially in caravans, motorhomes or boats.
  • Atmospheric burners draw their combustion air automatically from the immediate environment. Since the burners for the above applications, especially in caravans or motorhomes, must be independent of room air, the burners are usually placed directly on an outer wall or on the ground inside the passenger compartment and connected via a breakthrough with the environment to from there combustion air Respectively.
  • the combustion air is supplied to the burner and combusted in the burner with the fuel, e.g. LPG or liquid fuel mixed.
  • the exhaust gas is usually passed through a flexible pipe to the roof and there by means of a chimney piece to the outside. Due to the hot exhaust gases creates a chimney effect, which keeps an automatic discharge of the exhaust gases in motion. Due to the suction of the chimney effect prevails in the exhaust pipe always a slight negative pressure, which prevents leakage of exhaust gases from the exhaust pipe in particular at interfaces or sealing joints. In this way it can be achieved that no exhaust gas can enter the installation space or the passenger compartment. Further safety devices are not required.
  • the combustion air supplied to the burner on the one hand and the exhaust gases to be discharged on the other hand are conveyed by means of a combustion air blower.
  • This allows greater freedom in design and installation of the devices can be achieved.
  • the exhaust gases can be discharged via a side wall chimney and installation height of the device from the device and the interior be, without it depends on the above-described atmospheric effect (chimney effect).
  • the combustion air blower is arranged in the device, with the result that the exhaust gas is discharged by means of an overpressure in the lying downstream of the combustion air blower exhaust pipe.
  • the combustion air temperature is strongly coupled to the exhaust gas temperature because the pipe-in-pipe structure corresponds to a pipe heat exchanger.
  • the combustion air blower In order to compensate for the resulting volumetric flow fluctuations, the combustion air blower must be controlled depending on the combustion air temperature.
  • the invention has for its object to provide an exhaust device in which also a safe operation of heaters or other devices with gas or liquid fuel burners is achieved, but in which the influence of the exhaust gas temperature is reduced.
  • An exhaust device for a combustion device in a mobile space comprises: an exhaust passage for guiding exhaust gas from the combustion device into the environment, an air passage at least partially surrounding the exhaust passage and opened to the atmosphere, and a blower device arranged in the air passage for generating a Air flow in the air duct.
  • the air flow in the air duct has a flow direction towards the environment. In particular, the air flow in the air duct can be guided from the firing device to the environment.
  • the exhaust device has a safety device to ensure the discharge of any exhaust gas from the interior.
  • the air passage is thus located close to or close to the exhaust passage and surrounds the exhaust passage at least in areas where exhaust gas from the exhaust passage, e.g. can escape via separation or connection surfaces or joints.
  • the blower device ensures an air flow in the direction of the environment, so that exhaust gas that has escaped undesirably and has reached the air duct can be reliably removed to the environment.
  • the air flow in the air duct is independent of a supply of combustion air. Rather, a separate combustion air duct is provided for the combustion air supply, which can be arranged separately or integrated into the exhaust device with.
  • the air duct and / or the exhaust duct can be composed of several channel elements. It is common that such ducts or air ducts e.g. be assembled from dimensionally stable tubular elements and flexible hoses or tubes. Channel elements may also be air ducts or air ducts in geometries in burner heaters.
  • the air duct should surround the exhaust duct at least in an area where a sealing joint between two duct elements is provided in the exhaust duct. It has been found in practice that it can not be prevented due to the pressure prevailing in the exhaust duct overpressure that exhaust again and again seeks ways in which it can escape undesirable. Understandably, such sealing joints are understandably suitable for this purpose. Therefore, it may be expedient to design the air duct such that the exhaust gas exiting at the respective sealing joint via the air duct to the environment, that is discharged to the outside of the room to be heated out.
  • the term environment is to be understood below always in this sense.
  • the air duct surrounds the exhaust duct radially completely and axially at least in one section. Radially enclosing the exhaust passage through the air passage results in a tube-in-tube arrangement which ensures that any exhaust gas leaving the exhaust passage in an unforeseen way is taken up and removed from the air passage. Accordingly, the section should be chosen so that there is no further possibility for the exhaust gas to escape unchecked from the exhaust duct. In this tube-in-tube construction then the air flow is not, as in the prior art, from the environment to the burner, but vice versa, towards the environment.
  • the air duct may be formed as an over tube and enclose the exhaust duct designed as an exhaust pipe completely on the circumference.
  • the air duct may have a negative pressure section (suction section) located upstream of the fan device and an overpressure section located downstream of the fan device.
  • a negative pressure section suction section
  • an overpressure section located downstream of the fan device.
  • the downstream overpressure section should serve only for discharging the air guided in the air duct and, if appropriate, the exhaust gas components leaving the exhaust duct to the outside to the surroundings.
  • the negative pressure section and the overpressure section are arranged at least partially axially relative to one another. This allows a particularly compact arrangement of vacuum and overpressure section.
  • the negative pressure section and the overpressure section can then be separated from one another by a partition wall and thereby be placed axially very close to each other axially, in order to save installation space.
  • the negative pressure section and / or the overpressure section may be arranged at least partially coaxially with the exhaust gas duct and at least partially radially surround the exhaust gas duct.
  • the exhaust duct and the overpressure section of the air duct each have an orifice which leads into a common mixing area.
  • the hot exhaust gas it is possible for the hot exhaust gas to be mixed with the cooler air of the air duct in the mixing area so as to lower the exhaust gas temperature. It has been found that an exhaust gas temperature of initially 200 to 300 ° C is lowered by the mixture with the air from the air duct to a temperature value of less than 150 ° C.
  • the mouth of the air duct and the mouth of the exhaust duct may be immediately adjacent to each other to effectively assist in mixing the air flow with the exhaust flow.
  • the mouth of the air duct may radially open the mouth of the exhaust passage, i. Surrounded over the entire circumference. This initially forms a cooler protective jacket from the air flow of the air duct, which surrounds the inner hotter exhaust duct.
  • the blower device may be located near the mouth of the air duct.
  • the mouth of the air duct also corresponds to the end of the air duct. It is desirable that the blower device is placed as close as possible to the end of the air duct in order to achieve the largest possible negative pressure section upstream of the blower device. Only the negative pressure section is adapted to receive escaping exhaust gas from the exhaust duct.
  • the length of the overpressure section should be minimal with respect to the interior, so as low as possible.
  • the mixing area may be separated from the environment by an exit grid.
  • the outlet grille is located towards the environment and prevents the ingress of dirt, rainwater, etc. It also provides a safety device that prevents the hot exhaust gas flow exiting at the mouth of the exhaust duct from causing damage to people and the environment.
  • the adjoining the mouth part of the exhaust passage, the pressure section, a portion of the negative pressure section and the blower device can form a structural unit.
  • Both the exhaust duct and the vacuum section are usually formed in practice by a plurality of tubular elements which are plugged together or fixed together in a suitable manner.
  • the am Farthest downstream parts of the exhaust passage and the negative pressure section can form together with the fan means and the relatively short pressure section, the structural unit, which can be mounted very easily as a whole.
  • the structural unit can be mounted from the outside to a vehicle wall, when the exhaust device in a vehicle, such. a caravan or a motorhome is used. This results in better sealing options.
  • a heating system may be equipped with the described exhaust device, wherein the combustion device is provided in a heating device with a combustion chamber and the exhaust gas channel leads an exhaust gas flow from the combustion chamber to the environment.
  • the heating system may be suitable for heating air or water.
  • the heating system can be used in a mobile unit, so in particular a caravan or a motorhome or a boat.
  • the air duct can run between the heating device and the surroundings and adjoin at least a part of the firing device in the region of the heating device. This makes it possible for exhaust gas which escapes directly from the combustion device or in the heating device, that is to say even before it enters the exhaust gas duct, to be discharged through the air duct.
  • FIGS. 1 to 5 show views and sections of the same exhaust device. They are therefore partly described together.
  • An exhaust pipe 1 serving as an exhaust gas duct is surrounded on the circumference by an air duct 2.
  • the air channel 2 is divided into a negative pressure section 2a and a positive pressure section 2b.
  • the negative pressure portion 2a and the overpressure portion 2b surround the exhaust pipe 1 at the periphery.
  • a radial fan 3 serving as a fan device is arranged, which sucks air from the negative pressure section 2a and presses it into the overpressure section 2b. Accordingly, an air flow with the flow direction A arises in the air duct (see arrow).
  • the radial fan 3 is driven by a fan motor 4.
  • the exhaust pipe 1 leads into the interior of a living room or passenger compartment in a caravan, motorhome or boat or the like to a burner (burner) of a heater, not shown, left of the in the Figures 1 and 2 to arrange arranged exhaust device. Accordingly, exhaust gas flows in the direction of arrow B in front of the combustion device in the exhaust pipe 1 and exits at an opening 5 from the exhaust pipe 1 to in the in the FIGS. 1 and 2 to reach the right outside environment.
  • the mouth 5 is protected by an outlet grille 6, which on the one hand prevent the ingress of moisture or dirt into the exhaust pipe and on the other hand should avoid a direct outflow of the exhaust gas into the environment.
  • a mixing region 7 is formed, in which also the overpressure section 2 b opens via an orifice 8.
  • the hot exhaust gas from the exhaust pipe 1 thus mixes with the cooler air blown off by the radial blower 3 via the overpressure section 2b.
  • the exhaust gas temperature is lowered significantly so that the exhaust gas can finally escape at a lower, uncritical temperature via the outlet grille 6 into the environment.
  • the relatively long negative pressure section 2 a of the air duct 2 in relation to the overpressure section 2 b substantially completely surrounds the exhaust pipe 1. So is in the FIGS. 1 and 2 only a plastic nozzle of the negative pressure section 2a shown, on the upstream end, for example, still a flexible tube can be pushed, which is finally led to the heater or the combustion device, not shown.
  • the entire vacuum section 2a should therefore be designed so that it surrounds all areas of the exhaust pipe 1, but also optionally also the burner in the heater. It is important to ensure that especially at start of the heater by pressure surges escape exhaust gas at different points of the heater and can lead to impairment in the interior. Accordingly, it must be ensured that all sealing joints, joints, openings, etc., at which exhaust gas can escape in an uncontrolled manner at a corresponding overpressure in the system, are surrounded by the vacuum section 2a or are in fluid communication therewith. In this way, the undesirable discharged from the exhaust pipe 1 and other units exhaust gas is sucked through the negative pressure portion 2a due to the action of the radial fan 3 and finally blown through the pressure section 2b into the environment.
  • the negative pressure section 2a and the overpressure section 2b are arranged axially aligned with each other at least in a certain area.
  • a partition wall 9 is provided, which serves as a bulkhead and the negative pressure section 2 a separated from the overpressure section 2 b.
  • the partition wall 9 may be formed integrally with the exhaust pipe 1.
  • Both the air duct 2 and the exhaust pipe 1 may be formed of a plurality of sub-elements, although e.g. the exhaust pipe 1 is shown in the figures only as one piece. It should be noted, however, that the exhaust pipe 1 in the direction of the combustion device will have a significantly greater length than shown in the figures.
  • the entire exhaust device can - as in the FIGS. 1 and 2 shown - used as a unit in a vehicle wall 10 of a caravan or motorhome or other mobile device.
  • a dish made of a robust and impact-resistant plastic is provided, in which the components can be used or to which the components can be attached.
  • this also includes the exhaust pipe 1 and elements of the air duct 2.
  • the discharged via the air duct 2 air not only ensures a safe discharge of undesirable exiting exhaust gas. Moreover, even with a suitable design of the firing device or the heating device, it is possible to effectively cool critical areas.
  • Fig. 3 shows the outside view with the exit grille 6, which is placed on the vehicle wall 10.
  • Fig. 4 shows the rear view of the exhaust device from the inside.
  • an inflow nozzle 11 can be seen, via which fresh air can be conducted from the environment as combustion air to the combustion device.
  • the fresh air supplied via the inflow pipe 11 is mixed and combusted in a known manner with fuel (liquid gas, liquid fuel). This ensures that the combustion air used for combustion is not supplied from the heated interior, but from the environment.
  • the inflow pipe 11 is thus part of a combustion air duct, which is provided in addition to the air duct 2. While the air in the air channel 2 flows toward the environment, the air flows in the combustion air channel not shown in detail in the figures from the environment into the interior.
  • Fig. 5 to supplement a sectional view of the radial fan 3 and the fan motor 4 in the installed state in the vehicle wall 10, analogous to the other figures.
