Definitions

  • the present invention relates to an arrangement with at least two burners.
  • the arrangement generates warm air and/or heats water.
  • the arrangement can form a single device, but can also result from spatially distributed components.
  • each device has its own exhaust system and its own combustion air intake.
  • a leisure vehicle especially a mobile home or caravan
  • each of which has its own burner especially gas burner or liquid fuel burner
  • each device has its own exhaust system and its own combustion air intake.
  • any device combination can be installed at different installation locations and that mutual interference via the combustion air ducts and/or via the exhaust systems is ruled out.
  • a device can suffer damage as a result, because such a device is usually not designed for reverse flow at high temperatures.
  • the NL 1 014 990 C2 discloses an assembly consisting of a pipe part for conveying flue gas and a non-return valve, the non-return valve being completely contained in the pipe part.
  • a tubular body is provided that includes a valve seat and a movable valve. It has an outer peripheral shape and dimensions that correspond to the inner peripheral shape and dimension of the tubular member so that the tubular body fits within the tubular member.
  • the valve seat is located at one longitudinal end of the tubular body and extends around its circumference.
  • the tubular body has at its other opposite longitudinal end an extending clamping rib, the outer peripheral dimension of which is preferably at most 0.5 mm larger than the inner peripheral dimension of the tube part.
  • the EP 2 985 529 A1 describes a combustion system with a plurality of gas burners and a common exhaust pipe for the plurality of gas burners, wherein in burner-on phases of a respective gas burner this gas is burned and exhaust gas is produced which flows into the common exhaust pipe, and wherein in the burner Off phases of a respective gas burner, no gas is burned, with the common exhaust gas pipe being assigned a common exhaust gas sensor and in an operating state of the combustion system in which only a single gas burner of the plurality of gas burners is in a burner-on phase, while all other gas burners are in a burner-off phase, the signal supplied by the common exhaust gas sensor is used for combustion adjustment at least on the gas burner that is in the burner-on phase.
  • the object of the invention is to improve an arrangement that has at least two burners in terms of applicability.
  • the invention solves the problem by an arrangement with at least two burners, the arrangement having an exhaust gas routing device, the exhaust gas routing device of a common routing of exhaust gases serves at least two burners, the arrangement having a supply device, the supply device supplying combustion air to the at least two burners together, the arrangement having at least one non-return valve, the non-return valve preventing a flow of a gaseous medium in at least one flow direction, the non-return valve in the exhaust gas guiding device or in the air fuel supply device, wherein the non-return valve has at least one opening and at least one movable element, wherein the movable element is movable between at least two positions, the opening being in the event that the movable element is in one of the two positions is located, is open, and wherein the opening is closed in the event that the movable element is in another of the two positions, wherein the non-return valve is arranged in the exhaust gas guiding device, wherein each of the two ei burner exits from an exhaust duct, each exhaust
  • a common exhaust gas routing device and a common feed device are provided for the at least two burners.
  • the exhaust gas routing device is used for the joint removal of the exhaust gases from the at least two burners, which are each led out separately from the burners and together to an exhaust gas outlet, e.g. B. a chimney.
  • the combustion air supply device is such that the combustion air—as the air used in the combustion process—is fed separately from a common combustion air supply—as an air inlet—to each burner or to the components upstream of the respective burner.
  • At least one non-return valve is provided in the arrangement, which prevents a gaseous medium from flowing in an undesired direction of flow.
  • the flow direction of a gaseous medium that is blocked by the non-return valve can therefore also be referred to as the blocking direction.
  • the gaseous medium is in particular an exhaust gas.
  • the flow in a (blocking) direction is blocked by the at least one non-return valve or the plurality of non-return valves, thereby preventing exhaust gases from entering an undesired direction.
  • the non-return valve is arranged in the exhaust gas routing device or in the feed device.
  • the feed device preferably supplies the at least two burners together with combustion air.
  • a further advantage is that during operation without the involvement of all burners, it is prevented that the exhaust gases flowing backwards get back into the common combustion air intake via the burner with the combustion chamber that is not in operation. Otherwise the mixture formation for combustion would be negatively influenced by the exhaust gas recirculation and complete combustion could no longer be achieved. This would increase too CO values in the exhaust gas. If too much exhaust gas is drawn in, the flame on the active burner could also go out.
  • the arrangement relates in particular to burners with combustion chambers that are independent of one another (ie in particular burners with a combustion air fan).
  • the arrangement has only one common exhaust system and only one common combustion air intake, with combustion chambers that are independent of one another.
  • the non-return valves function as a type of valve that allows flow only in the preferred direction and prevents or at least sufficiently reduces flow in the opposite direction.
  • the non-return valves (alternatively called: non-return valves) preferably have an almost negligible flow resistance in the direction of flow, so that they have a low and preferably negligible pressure loss in the direction of flow.
  • the non-return valves open slightly in the event of pressure differences in the permissible direction of flow, thereby releasing the largest possible flow cross-sections. Contrary to the direction of flow, they preferably close automatically even without a pressure difference and, moreover, reliably withstand the designed pressures.
  • the non-return valves and in particular the materials used are preferably designed in such a way that they reliably withstand the mechanical and thermal loads that occur over the intended period of use.
  • the opening and closing functions of the non-return valves are preferably designed in such a way that accelerations acting from the outside have as little or no effect as possible. This is of particular importance when used in a leisure vehicle in which the burners with combustion chambers are also operated while driving. This is inevitably caused by bumps in the road and by braking or accelerating the vehicle to accelerations also at the non-return valves.
  • the non-return valve or non-return valves only have moving parts with a very low mass, so that the non-return valves are hardly affected in their function when there is an acceleration acting from outside (for example due to operation while driving in a motor vehicle).
  • non-return valves should be able to be produced particularly inexpensively, and the additional effort involved in installing the heater should be as small as possible.
  • non-return valve there is at least one non-return valve at a point (seen from the supply device to the exhaust gas routing device and thus in the direction that the combustion air takes under normal conditions) downstream of a combustion air fan, but in front of the combustion chamber of the associated burner.
  • a non-return valve in front of the combustion air fan, but behind the branching of the combustion air supply to the individual burners.
  • the arrangement has several fan-supported burners that are to be used in combination with other devices in such a way that they only have a common exhaust gas outlet or a common combustion air intake.
  • the burners with combustion chambers are installed in different devices and, in an alternative embodiment, are located within an overall device. For example, if it is divided into several separate devices, one device can be used for warm air heating and a second one for hot water preparation (different basic functions). However, it is also conceivable to combine a first device for warm air heating with a second device for warm air heating.
  • One embodiment provides that at least two non-return valves are present.
  • One configuration includes that one of the two non-return valves is arranged in the exhaust gas routing device and that another of the two non-return valves is arranged in the feed device.
  • each of the two burners is preceded by one of the two non-return valves in the feed device. Upstream in relation to the combustion air, so that the combustion air first passes through the non-return valves and only then through the burners.
  • One embodiment includes that the feed device has at least one blower device, and that the non-return valve is arranged between the blower device and one of the two burners.
  • the non-return valve is located between the blower device and the associated burner in the direction that the combustion air takes under normal or standard conditions from the supply device to the exhaust gas routing device. If, in this embodiment, hot exhaust gases get into a burner that is not in operation, the associated non-return valve prevents the exhaust gases from getting any further to the blower device.
  • the feed device has at least one blower device, and that the blower device is arranged between the non-return valve and one of the two burners.
  • the non-return valve is located in the direction from the supply device to the exhaust gas routing device—and thus in the direction that the combustion air takes under normal conditions—in front of the blower device and in front of the burner, which is arranged downstream in this direction and is assigned to the blower device.
  • the blower device is to be designed in such a way that it tolerates higher temperatures, such as are typical for exhaust gases, for example.
  • the section between a burner and the feed device is sealed off by the non-return valve in such a way that if the associated burner is not being operated, there is no negative pressure in the area of the burner that is not in operation, so that no exhaust gases from the burner in operation get into the burner that is not in operation.
  • One configuration includes that the non-return valve is arranged in the exhaust gas routing device.
  • the non-return valve in the exhaust gas routing device in particular prevents exhaust gases from being fed from an operated burner to an inoperative burner, since the exhaust gas is blocked directly.
  • the non-return valve is located in particular in the area in which the separate exhaust gas paths of the at least two burners are brought together.
  • a non-return valve that acts on both sides is arranged at the point at which the individual exhaust gas channels of the burners come together.
  • the non-return valve can thus allow a gaseous medium to flow in two directions.
  • the non-return valve placed there closes the flue gas duct of the non-operating burner when only one burner is in operation.
  • the valve flap assumes a middle position in one embodiment, depending on the volume flow in the two exhaust gas ducts, in order to enable exhaust gas to be discharged together from this point.
  • there is the advantage of only requiring a non-return valve for the burners which can lead to a cost advantage overall.
  • the non-return valve has at least one opening and at least one movable element, that the movable element can be moved between at least two positions, that the opening is open when the movable element is in one of the two positions, and in that the opening is closed in the event that the movable element is in another of the two positions.
  • the non-return valve is preferably designed in such a way that the movable element automatically moves into the position in which the opening is closed when there is no pressure.
  • the non-return valve is designed in such a way that the movable element is actuated by a gaseous medium, e.g. B. by the combustion air or by a combustion air-fuel mixture from the one position can be moved to the other position.
  • the non-return valve preferably closes the opening when no gaseous medium acts on the movable element or when a gaseous medium acts on the movable element from a blocking direction. However, if a gaseous medium flows in the forward direction, the movable element releases the opening.
  • the movable element is a centrally mounted diaphragm—in particular one made of an elastomer.
  • the membrane rests with a freely movable edge on a bearing point surrounding the membrane.
  • the bearing point is therefore a bearing surface for part of the membrane.
  • One embodiment provides that the movable element closes the opening when it rests in a bearing point, and that the movable element can be moved away from the bearing point by a gaseous medium.
  • One embodiment includes that the movable element is at least partially elastic, and that in the event that a gaseous medium flows against the movable element from one direction, the movable element deforms elastically in such a way that the opening is uncovered.
  • the movable element is thus designed in the manner of a nozzle, which has an end face with the opening. The gaseous medium ensures that the movable element deforms appropriately, thereby releasing the opening.
  • the movable element is designed as a nozzle, that a tip of the nozzle restricts the opening, that the movable element is at least partially elastic, and that the movable element in the event that a gaseous medium the movable element of a Direction flows, elastically deformed in such a way that the opening is released.
  • the movable element is a flap that is mounted decentrally or on one side.
  • the flap is preferably made of a material that is suitable for higher temperatures and so designed and is stored that, for example, exhaust gases allow tilting of the flap.
  • the storage does not take place around the center of the movable element, but offset to it. Due to the bearing, the mass of the flap is also unevenly distributed around the bearing point.
  • One embodiment includes that the non-return valve is arranged in the exhaust gas routing device, that an exhaust gas duct emanates from each of the two burners, that each exhaust gas duct is assigned an opening, that the movable element is a flap mounted decentrally or on one side between the two openings, and that a Position of the damper depends on a ratio of the exhaust gas volumes of the two burners.
  • the supply device supplies the two burners with a mixture of combustion air and a gaseous fuel or a liquid fuel that has been converted into a gaseous state.
  • the backflow blocking device is at least one blower device of the feed device, and that the feed device also supplies one of the two burners with combustion air via the at least one blower device when the burner is not in an operating state.
  • the reverse flow blocking is thus provided by at least one fan device and the blocking direction is the direction opposite to the direction of the combustion air (under normal conditions from the supply device to the exhaust gas routing device).
  • a burner that is not in an operating state and is therefore not in operation is supplied with combustion air, so that the combustion chamber of the burner that is not in operation is flushed with combustion air.
  • the combustion air thus also passes through the burner that is not in operation and reaches the exhaust gas routing device as exhaust gas.
  • the blower device is operated in such a way that the energy consumption is reduced as much as possible.
  • the speed of the combustion air fan is monitored by a control unit in such a way that the speed does not fall below the minimum speed required to prevent backflow.
  • the rotational speed of the combustion air fan is measured.
  • a temperature is measured, the temperature being measured at such a location that penetrating exhaust gases increase the temperature.
  • the temperature in or on a combustion air fan is determined.
  • a temperature is generally measured in such a region through which the combustion air flows during normal operation and is thus upstream of at least one burner. If the temperature rises above a tolerance range, this means that exhaust gases have been recirculated because the associated burner is not flushed with sufficient combustion air. The speed of the combustion air fan must therefore be increased in order to prevent backflow.
  • the blower device of the burner that is not in operation is operated in such a way that there is no risk of the exhaust gas flowing back, but that full output of the blower device is avoided.
  • the 1 shows schematically an arrangement 1 with two burners 10, each of which has its own burner space.
  • the burners 10 each receive their combustion air via a supply device 3 which has a single combustion air supply 31 .
  • the combustion air is supplied to the burners 10 via a fan device 30 in each case.
  • the exhaust gases of the two burners 10 are discharged via a common exhaust gas routing device 2 after they have left the burner 10 via their own exhaust gas outlets. So they are Combustion air inlets of the two burners 10 are coupled to one another and the exhaust gas outlets of the two burners 10 are coupled to one another.
  • exhaust gases are primarily prevented from entering the blower devices 30 . This is done here by a backflow blocker 4 between a fan device (alternative name: combustion air fan) 30 and the associated burner 10 is arranged.
  • a gaseous medium can only flow through the non-return valves 4 in the passage direction (indicated by the arrows drawn in) and thus in the direction of the burner 10 .
  • the non-return valves 4 close the path and thus in particular also prevent exhaust gases (as a gaseous medium) from entering the blower devices 30 .
  • the non-return valves 4 are upstream of the blower devices 30 with respect to the combustion air and are therefore arranged further in the direction of the combustion air supply 31 .
  • This configuration makes it possible, for example, to design the two blower devices 30 and the combustion air supply 31 as a common component. This simplifies production.
  • non-return valves 4 are arranged at different positions of the feed device 3 .
  • the following configurations relate to exemplary configurations of the non-return valves 4 themselves.
  • the 3 shows a non-inventive non-return valve 4 with an elastically movable membrane as a movable element 41.
  • the membrane 41 is - here via a screw - stored in the middle.
  • the opening 40 is thus open.
  • the 4 shows an embodiment not according to the invention with a movable element 41, which is designed here as a disc and serves as a floating body.
  • the opening 40 is open and the medium can pass.
  • the movable element 41 has to be made correspondingly light, so that it can be lifted by a gaseous medium.
  • several (preferably at least three) clamping hooks are provided in the embodiment shown, which prevent a lateral movement of the movable element 41 and limit the axial movement upwards.
  • a surrounding edge is provided as an alternative to the clamping hooks.
  • FIG. 12 shows a movable element 41 which is designed in the form of a nozzle and is designed to be elastic.
  • the opening 40 is thereby restricted by the upper tip of the nozzle 41 . If the gaseous medium presses against the tip of the nozzle 41 from below, the material expands and the opening 40 is released. Without the flow from this direction, the tip preferably closes by itself, as shown here. If, in addition, a gaseous medium presses against the upper end face of the movable element 41 from above, the tip and thus the opening 40 are also closed.
  • the mobility of the movable element 41 thus relates either to the mobility in relation to the position and/or in relation to the geometry and the change between different geometric states of the element 41.
  • the 6 shows a similar embodiment of the arrangement 1 as the 2 .
  • there is also a non-return valve 4 in the exhaust gas routing device 2 which is assigned to both burners 10 .

  • the exhaust gas from the right-hand burner pushes the cantilevered movable element 41 in the direction of the burner, which is not in operation and is arranged here on the left. Due to the arrangement and the configuration of the movable element 41 designed as a flap, the opening 40 on the left-hand side of the line system is thereby closed and the exhaust gas cannot reach the other burner. If the left and not the right burner were operated, the flap 41 would close the opposite opening 40 .
  • the 8 shows the case that the burner on the left has a higher output than the burner on the right (cf. 6 ) is operated.
  • the damper 41 assumes a tilted position in accordance with the relationship between the amounts of exhaust gases, so that again for the burner with the lower exhaust rate, the opening is more closed.
