Definitions

  • the invention described here is a fired heat exchanger for liquid heaters designed to be best utilised in throughflow water heaters.
  • a fixed heat exchanger according to the preamble of claim 1 is known from document EP0825392 .
  • the invention features a solution where the fired heat exchanger for liquid heaters is equipped with a spiral tubular heat exchanger with a heated liquid medium whose each coil in the cross-section has a point contact with adjacent tube coils. After their inseparable thermal linear integration, a uniform surface of the combustion chamber is created together with the heat medium flow chamber in the further part of the unit.
  • a tubular multi-chamber core inside the spiral tubular heat exchanger.
  • the internal shape of the tubular multi-chamber core directs the air stream to flow around all its internal surfaces, which prevents the core from overheating. At the same time, the air, to be used in later thermal processes for liquid heating, is heated as well.
  • the invention features a solution where the construction of the fired heat exchanger for liquid heaters makes it possible to lower the exhaust gas temperature below the dew-point, which results in condensation of moisture contained in the exhaust gases, which, in turn, has a favourable ecological effect.
  • Another advantage of this solution is the possibility of fitting the latest generation burners to the heat exchanger, which enables their users to optimally minimise the emission of detrimental combustion products to the air.
  • the design of the invention facilitates gaining very favourable operational parameters and a high degree of thermal efficiency. Additional features are a simple, compact and light housing and the ease of operation.
  • FIG. 1 An example of the subject of the invention is shown in the picture attached. It depicts a fired heat exchanger for liquid heaters in the axonometric view with a broken-out section of the side part of the device featuring a view of the internal structure.
  • the fired heat exchanger for liquid heaters is built from a spiral tubular heat exchanger (1) which heats the liquid medium.
  • each coil of the tube in the cross-section has a point contact with adjacent tube coils.
  • a uniform surface of the combustion chamber (2) is created together with the heat medium flow chamber (3) in the further part of the unit.
  • the internal shape of the tubular multi-chamber core (4) directs the air stream to flow around all its internal surfaces, which prevents the core walls from overheating. At the same time, the air used in later thermal processes of liquid heating is heated as well.

Claims (1)

  1. Befeuerter Wärmetauscher zur Fluiderwärmung, der für gemeinsamen Betrieb mit einem Brenner, insbesondere einem Gasbrenner ausgelegt ist, mit einem spiralen Rohrwärmetauscher (1) mit einem zu erwärmenden flüssigen Mediums, in dem jede Rohrwicklung in Querschnitt einen punkförmigen Stoß mit anliegenden Rohrwicklungen aufweist, die nach ihrem thermischen, unlösbaren, linearen Verbinden eine einheitliche Oberfläche der Brennkammer (2) und der Durchflusskammer des Heizmediums (3) in weiteren Teil des spiralen Rohrwärmetauschers (1) bilden, in dessen Inneren sich ein Kern befindet,
    dadurch gekennzeichnet, dass als der Kern ein Rohrmehrkammerkern (4) eingesetzt ist, auf dessen äußeren Oberfläche unlösbar, die gesamte Länge entlang, radial verteilt, plattenartige Lamellenbauteile (5) angebracht sind,
    durch die ein labyrinthähnlicher Durchfluss des Heizmediums sichergestellt ist und die innere Form des Rohrmehrkammerkern (4) den Luftstromdurchfluss ausrichtet, der alle seine inneren Oberflächen abwäscht, was seiner Überhitzung vorbeugt und zugleich die Luft erwärmt, die anschließen in weiteren Wärmeprozessen der Fluiderwärmung eingesetzt wird.
