Definitions

  • the invention relates to a boiler for connection to the heating circuit of a hot water heating system a burner opening and an exhaust opening, formed essentially hollow spherical Combustion chamber and a thermally connected to the combustion chamber, a return connection and a flow connection for the water circuit with the heating circuit.
  • Boilers have a mostly cylindrical design, the one between an inner and an outer jacket arranged, through which the heating water flows convectively Has water space.
  • the heating water becomes the water room removed from the flow connection and from another Point returned via the return connection.
  • the temperature differences inside of the boiler are reinforced by the geometric Asymmetries and dead spaces in the boiler, in particular in the area of the burner door and the flue gas nozzle. This exists especially in the low temperature range Danger of falling below the dew point in the flue gas and thus rapid corrosion.
  • the invention has for its object a boiler to develop the type specified at the outset lightweight design with the largest possible combustion chamber surface easy to manufacture and assemble from just a few parts and which is still largely uniform Thermal load of the entire combustion chamber surface guaranteed is.
  • the solution according to the invention is based on the idea that when using a substantially spherical Combustion chamber both radiation-optimized as well flow-optimized heat transfer with largely ensures uniform loading of the combustion chamber surface is.
  • the substantially hemispherical Interior surfaces complement the combustion chamber and in the wall of water pipes with forced flow molded into the water space or form-fitting are embedded.
  • the burner opening is there Appropriately on one and the exhaust opening on the the other half of the boiler. You get through it a completely cooled combustion chamber without uncooled burner door.
  • For maintenance purposes only need the two boiler halves pivoted against each other or to be lifted off from each other.
  • the two boiler halves conveniently on one Separating flange delimiting spherical great circle detachable connected, the separating flange of each Half of the boiler with an annular dividing surface semicircular groove for receiving a sealing strip can have.
  • the boiler halves essentially have hemispherical, complementary to a full sphere Outside surfaces.
  • the burner opening and the exhaust opening can each by one in the area a small ball circle concentric to the separating flange molded flange are limited.
  • a particularly light construction and high heat resistance is achieved when the boiler halves are made of aluminum, preferably made of die-cast aluminum with cast-in Stainless steel water pipes. If the two boiler halves are of the same design, can they are made with the same mold.
  • the return ports open expediently in a common return collector, while the flow connector in a common Flow collector.
  • the return collectors and the Flow collectors of the two boiler halves are advantageous through flexible hose lines with each other connected so that they open against each other to open the boiler pivoted or separated can.
  • Water space has at least one of the boiler halves in the Angular distance from each other, away from the separating flange extending to the burner or exhaust opening, Radially protruding thermal fins on.
  • the boiler half having the exhaust gas opening is preferably one supporting on the free rib edges, expediently used hemispherical impact pot so that between the baffle outer surface and the inner surface of the boiler a possibly through the heat-conducting fins divided flow space for the exhaust gases is formed becomes.
  • the flow space has one from the inlet gap near the separating flange to the exhaust opening towards the volume reduction of the Fuel gases in the flow direction decreasing flow cross-section on.
  • the temperature sensor for the boiler temperature control and safety temperature limitation in provided sensor pockets, which are in the course of the casting process are molded to accommodate.
  • the boiler according to the invention is primarily for oil and gas burners with the shortest possible spherical Suitable for flames.
  • the one shown in the drawing is essentially hollow spherical Boiler 10 is for use in a Hot water heating system determined. It essentially exists from two identically designed boiler halves 12, those bounding a great circle of the boiler ball Separating flange 14 detachable with one another via flange eyes 16 connectable and with the separating flange 14 open Cleaning and maintenance purposes in the direction of the arrow 18 pivotable against one another about the swivel joint 20 are.
  • the separating flanges 14 have an annular shape Flange surface 58 in which one is over half Flange surface extending groove 60 for receiving a not shown sealing strip is molded.
  • a further flange 22 is formed, which has an opening 24 limited and the 12 on the upper half of the boiler for connecting a burner 26 and to the lower one Boiler half 12 for connecting an exhaust pipe 28 is determined.
  • the preferably stainless steel water pipes 30 are with their elbows 32 in the course of production for example in the die-casting process in aluminum cast existing wall material of the boiler halves 12.
  • the pipe bends 32 are concentric with each other and to the separating flanges 14 on small circles Shell halves 12 arranged so that they are on the spherical Partial outer surface 33 of the boiler halves survive and on their bent return and flow connection 34 root-cast in and over stabilizing Crosspieces 38 connecting piece holders connected to one another 40 are guided to the outside in a stable manner (cf. in particular 3, 4 and 7).
  • thermal fins 46 formed.
  • a burner tube 45 extends through the side of the burner 26 the opening 24 into the combustion chamber 44, via the under A largely spherical flame 47 is produced.
  • the radiated from the surface of the flame Heat predominantly reaches the inner surface 42 on the burner-side boiler half 12 and is there over the promoted in forced circulation through the water pipes 30 Heating water discharged to the flow side.
  • the one when burning generated hot flue gases reach the Side of the flame tip in the baffle pot 48 and there in the direction of arrows 54 giving up their heat content via the thermal fins 46 and the inner surface 42 to the heating water flowing in the water pipes 30 directed to the exhaust pipe.
  • the resulting one Volume decrease is due to the cross-sectional decrease along the flow space 52 while maintaining a almost constant flow velocity of the flue gas compensated.
  • the invention refers to a boiler 10 for connection to the heating circuit of a hot water heating system.
  • the combustion chamber 44 of the boiler in substantially hollow spherical.
  • the purpose is two boiler halves that can be pivoted against each other provided whose essentially hemispherical inner surfaces 42 face the combustion chamber 44 complete and in the wall forced water pipes 30 are positively embedded.
