Definitions
- the present invention relates to a Burner-equipped boiler or instantaneous water heater, with a casing enclosing a boiler room, a jacket-shaped heat exchanger, which converts the boiler room into a Combustion chamber and an exhaust chamber split and over the The lateral surface distributes passages for hot combustion gases has, and one arranged in the combustion chamber Burner head according to the preamble of patent claim 1.
- GB-A-792 747 discloses a boiler with one Boiler room, which is made up of a heat exchanger special coiled pipe into a pipe wrapped by the heat exchanger Fire chamber and an exhaust gas chamber surrounding the heat exchanger divides. Opposite an arranged on the front, Fireclay flame pot, in which for the commissioning of the Arrange a boiler head, not shown, in the boiler is a head assembly is formed on which the hot gases are redirected and swirled. Through the Turbulence gets unburned gases from the periphery back to the central flame.
- the influx of fresh ignited air / fuel mixture into the combustion chamber creates an overpressure with which the exhaust gases openings between the windings of the heat exchanger tube in a ring channel outside the heat exchanger become.
- the exhaust gases can be close to the head arrangement get into a first ring channel, in this to Flow on the burner side and in a second outer ring channel back again. In a simpler embodiment they reach the burner side within the combustion chamber, and step through the openings into the ring channel. In this The flue gas flows in the other direction again to a fireplace.
- a burner head is inside the flame pot to arrange which is the heat exchanger before the radiant heat protects the flame and the burner head.
- a recirculation of the exhaust gas in the flame is only in the boiler room provided outside the flame pot. With one Boilers can therefore only use high fuels Burn exhaust emissions.
- a boiler according to the The preamble of claim 1 is known.
- the boiler is with a vertical spiral tube as a heat exchanger Mistake.
- On the top of the boiler is a burner head Fall burner arranged.
- Opposite the fire opening of the The lint burner's flame cup is a concave one Firebrick arranged.
- the heat exchanger is arranged, which an annular one arranged around the heat exchanger Separates the hot gas flue from the combustion chamber.
- the turns of the spiral tube are in one middle area tight. Through increasing openings the gas enters between the end turns of the helical tube the outer hot gas flue, where it is down again and again passed through the heat exchanger into an exhaust pipe becomes
- the disadvantage of this boiler is that the temperature the heating gas in the outer heating gas flue is still so high that radiant heat from one that surrounds the heating gas flue and on the Heat exchanger can be transferred.
- the heating system should an oil or gas burner can be operated.
- One advantage of the boiler according to the invention is in that it can be heated with burners, which one have lance-shaped flame. Such a flame is needed usually one elongated in the direction of the flame Firebox.
- An arranged according to the invention Flame deflecting part allows the length of the Shorten the combustion chamber significantly. The deflecting part directs the Flame back to its starting point and shorten it Boiler room about half the length. This is the Combustion chamber almost filled with a flame, which comes from a flame tube in one direction and on the deflection part redirected in the opposite direction burns.
- the rear part of the flame forms an axial core flow and the front part of the flame one around the core flow opposite mantle flow arranged around.
- the Returning the flame to its root has continued Advantage that immediately after lighting the flame around the There are hot gases around the flame tube, which are suitable for the Improvement of the cold start behavior can be used.
- Another advantage is that by turning the flame Furnace is better used and more compact than with a long, thin flame shape. In particular the entire length of the firebox is practically uniform suitable for heat transfer to a heat exchange medium, because the burning head is covered by the flame.
- the heat exchanger advantageously has at or near at least one end of a final organ, which the Combustion chamber limited in the longitudinal direction. This is in addition to the exhaust gas chamber around the heat exchanger formed yet another chamber in which exhaust gas from the Exhaust chamber flows. This exhaust gas is now through the Heat exchanger is already cooled and can be used to cool the flame partly recirculated into the flame tube and partly through a chimney be drained.
- a closing body advantageously divides its side facing away from the combustion chamber from the boiler room outflow chamber connectable with a chimney. Such Outflow chamber lies axially in the boiler. So she takes it Flue gas from the periphery evenly. Unilateral Loads on the heat exchanger can thus be avoided.
- a closing organ from the boiler room advantageously divides one Recirculation chamber.
- Cooled exhaust gas can be used to cool the flame into the flame tube be recirculated.
- the recirculation chamber can also be the outflow chamber. It is advantageous the exhaust gas discharge chamber partitioned off by a closing element or / and the recirculation chamber from the heat exchanger encased. As a result, what flows into these chambers becomes Exhaust gas additionally cooled before it leaves the boiler room or performs its cooling task.
- the exhaust gas is through the double contact with the heat exchanger up to about 80 Degrees cooled, even under continuous operation Full performance. This allows the flue gas to go directly to the boiler be drained into a plastic fireplace.
- the closing body advantageously points between Combustion chamber and exhaust gas outflow a bulge for Exhaust gas outflow chamber open to extend the combustion chamber and the outflow chamber does not take up too much space claimed. Expediently through such Bulge the heat exchanger area around the Exhaust gas outflow chamber in relation to its volume kept large.
- the flame deflecting part advantageously forms Closing organ, so the number of parts required can be reduced.
- the arrangement of the Deflection part at a distance from the housing wall also acoustic Benefits.
- This closing body is expediently or Flame deflection part bulged out towards the outflow chamber.
- the flame deflecting part expediently has one on the flame axis, the flame opposing flame dividers and one around them annular deflection channel.
- the flame divider divides the Flame apart and the deflector guides the flame parts so that their flow direction is turned through 180 °.
- the Deflection channel is advantageously uniform all round designed so that the flame even after the deflection has a uniform shape.
- the jacket of the heat exchanger advantageously consists of with space next to each other, which the combustion chamber arranged extensively and to a feed and a Discharge are connected.
- These are expediently Heat exchanger tubes wound helically.
- Such a heat exchanger jacket is easy to manufacture, exhibits a large surface and passages between the pipes on.
- pipes can a smaller wall thickness and thus a more dynamic one Have heat transfer, which is characterized by a higher Performance noticeable in a small footprint.
- the jacket of the heat exchanger is advantageous from a A plurality of heat exchanger units put together. The Individual heat exchanger units face each other a heat exchanger with a single one, but all the longer Pipe, a smaller length of pipe, causing the Flow rate can be increased.
- the heat exchanger units are expedient therefore connected in parallel to the inlet and outlet.
- Heat exchanger units according to the in French Patent No. 93 00498 Heat exchanger elements applied. These stand out other by a flattened pipe cross-section, which rounds out the exchange surface Cross sections is also enlarged.
- Heat exchanger units also in that their production is already running for gas water heaters and therefore in excellent quality available on the market.
- the burner is advantageous for exhaust gas recirculation equipped to meet the exhaust gas values prescribed today, especially in the case of frequent cold starts. Even if gas burners are used in the boiler according to the invention can find, so the burner is advantageous Oil burners because oil can be stored in simple tanks and these can easily be refilled. The dependence from a pipeline network can thus be avoided. The Handling oil is also much less dangerous than the handling of gas which, so it is not through a network is distributed under pressure in appropriate pressure tanks must be filled.
- the burner is advantageously switchable or switchable on gas operation. If the burner head for both oil and oil Alternatively, these two media can be used with gas little additional installation effort, in the same Plant can be used. This has the advantages that e.g. on Price developments that can be responded to are higher Security against delivery bottlenecks exists or through Installation of a temporary oil tank on a projected creation of a gas supply line can, etc.
- an air supply duct is expediently designed as a mixing tube for the admixture of gaseous fuel.
- the inlet openings in the flame tube for the fuel / air mixture or the recirculated exhaust gas are advantageously designed such that the fuel / air mixture and the exhaust gas mix in a hollow cylindrical or frustoconical vortex zone. Due to these similar methods, the same flame tube can be used for both oil and gas.
- the oil nozzle can even remain in the system during gas operation or the gas supply means during oil operation, so that there is a two-media firing system with a single burner.
- these burners achieve exhaust gas values of less than 60 mg NO x per kW for oil and less than 20 mg NO x for gas.
- the CO values of 16 mg / kW are also at a low level. Apart from this, excellent cold start behavior is achieved with this burner.
- This flame chamber jacket ensures one even distribution of the hot smoke gases to the Heat exchanger and forms an ash catcher. It protects the Heat exchanger before direct contact with the flame. Thereby the distance between the flame and the heat exchanger can be very small being held.
- This flame chamber coat also has an effect positive on noise insulation. They are advantageous Passages arranged so that the flue gases are approximately tangential flow out of the flame chamber jacket because they are in one common direction of rotation ordered the heat exchanger jacket flow through tangentially. This is the Heat transfer versus radial heat transfer Flow direction improved.
- the housing advantageously has an installation in Enabling wall heater or plug-in kitchen unit Dimensions on.
- the housing with air supply and exhaust duct can have a length of up to approx. 50 cm.
- a the short version comes with a good 30 cm boiler length. This allows for a separate room for this heater to be dispensed with. It can be stored in a closet become.
- a supply air line in counterflow is advantageous the flue gas pipe arranged to allow the air to pass through the waste heat is preheated in the flue gas.
- This is expedient Blower arranged next to the housing and a supply air duct from Fan on one end of the housing and on the burner head led to the length or depth of the plant as small as possible to keep.
- Essential housing parts are expedient and / or the heat exchanger made of austenitic stainless steel manufactured, which is resistant to the aggressive exhaust gases and condensates.

- the heat exchanger 15 consists of individual elements 43, which are parallel and / or are connected in series to an inlet or outlet.
- the A deflection part 39 is arranged opposite the flame opening 37. This deflection part 39 forms a closure member 27 or is connected to a closure member 27.
- the closing body 27 sits between two tubes 40 or between two elements 43, so that the hot exhaust gas through the spaces 41 from the combustion chamber 17 into the exhaust chamber 19 and from there again between the pipes 40 into the outflow chamber 29 must flow.
- the exhaust gas can then flow out of the outflow chamber 29 through the opening 31 into a fireplace or a Step over the exhaust pipe.
- the deflection part 39 forms on the axis 45 of the Flame tube 23 or the boiler 11 an increase 47, which opposes the flame and divides it symmetrically.
- the Flame is through the deflection channel 49 in one of the original direction of flame opposite direction deflected and strikes between the flame tube 23 and the Heat exchanger tubes 40 back against the flame root. This creates an approximately cylindrical flame body of about double the flame tube diameter and the hot exhaust gases are through the entire length of the combustion chamber 17 Gaps 41 conveyed between the tubes 40 where an exchange of energy with that flowing in the tubes 40 Heat transfer medium takes place.
- the deflection part 39 is basin-shaped and sits with its bottom 49 near that opposite the flame tube Front of the housing 13.
- the outer pool rim 51 closes almost flush with the outer channel edge 53 of the Deflection channel 49 between the heat exchanger tubes 40 to this and the pool wall 55 runs obliquely from the edge 51 of the Heat exchanger tubes 40 away, so that none of the tubes 40 through the depth claimed by the deflection part 39 is covered.
- the the space occupied by the basin-shaped deflection part 39 opens up Cost of the outflow chamber 29, which thereby necessary minimum dimension is reduced.
- the combustion chamber 17th is opposed by this form of closing body 27 the outflow chamber 29 extended. So that the length of the boiler room can be minimized.
- a cover 57 is arranged, which is connected to the housing 13 is screwed.

- the flame tube 23 is located near the baffle plate 61 Recirculation openings 35 through which exhaust gas from the Space 65 between heat exchanger 15 and flame tube 23 in the Flame tube to be recirculated.
- the exhaust gas encased in Flame tube 23 a centrally let air flow. Thereby the flame tube is immediately after the ignition of a flame hot exhaust gas and immediately becomes hot itself.
- an oil nozzle 67 is provided which the fuel through the central air flow into the Exhaust jacket sprays. The fuel evaporates in the exhaust jacket. The vaporized fuel is now together with the exhaust gas swirled in the air. The flame burns blue because of the whole Fuel is gasified before flame formation.
- the same burner head can be used for gas operation. Only the gaseous fuel is added to the air, preferably on the vacuum side in the fan.
- the flame tube 23 becomes hot and transfers a certain amount of energy to the heat exchanger 15 by radiation. This effect is desirable, especially because blue-burning flames otherwise emit little radiant energy.
- the exhaust gas values are very low in both operating modes:
- the NO X emissions are below 60 mg / kW in the case of an oil fire and below 20 mg / kW in the case of a gas fire.

- the connecting links 133 have a stepped, themselves tapered silhouette on.
- Paragraphs 137 in the stairs are on the flame tube side of the baffle plate 113 and thus define the opening width of the recirculation slot 135. Exhaust gas becomes through this recirculation slot 135 along the baffle plate 113 and the aperture insert 125 in the Flame tube 115 sucked to soot this area to prevent.
- a favorable opening width is around 1 mm.
- the flame tube 115 has recirculation openings 139 through which the exhaust gas through the Vacuum, which is downstream of the baffle plate 113 due to the Air flow is created, is sucked in.
- the openings 139 can but also in a different number and / or other form.
- the flame tube 115 has an inner diameter of about 80 mm and a length of about 160 mm. At the The combustion chamber 112 facing the end of the flame tube 15 is this constricted. The constriction 141 narrows the Flame outlet opening 143 opposite Flame tube cross section. The edge area 145 of the flame tube 115 is round inward to form the constriction 141 turned.
