Description

  • 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 .
  • Taking into account the current level of technology, well-known and widely utilised water heater solutions are characterised by a heat exchange rate whose outlet gas temperature is so high that it makes it impossible for the process of condensation of steam in exhaust gases to occur. This effect lowers the heat exchanger efficiency rate together with other operational parameters. Moreover, burners used in current solutions do not always facilitate the process of lowering the content of detrimental combustion products, which adversely influence the natural environment.
  • 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. There is a tubular multi-chamber core inside the spiral tubular heat exchanger. There are radially distributed plate lamella elements inseparably fitted on the external surface of the core, thanks to which a maze-like heating medium stream flow system is achieved. 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.
  • 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. In the spiral tubular heat exchanger (1) each coil of the tube in the cross-section has a point contact with adjacent tube coils. After their inseparable thermal linear integration (e.g. by means of a soldering technique), 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. There is a tubular multi-chamber core (4) inside the spiral tubular heat exchanger (1). There are radially distributed plate lamella elements (5) inseparably fitted (e.g. by means of a soldering technique) on the external surface of the core, thanks to which a maze-like heating medium stream flow system is achieved. 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. fired heat exchanger for liquid heaters is designed to work with a burner, in particular a gas burner, the fired heat exchanger comprising a spiral tubular heat exchanger (1) for a liquid medium to be heated where each coil of the tube in the cross-section has a point contact with adjacent tube coils creating, after their inseparable thermal linear integration, a uniform surface of a combustion chamber (2) together with a heat medium flow chamber (3) in the further part of the unit, there being a core inside the spiral tubular heat exchanger,
    characterized in that the core is a tubular multi-chamber core (4) whose internal surface features radially distributed plate lamella elements (5) inseparably fitted on the external surface of the tubular multi-chamber core,
    thanks to which a maze-like heating medium stream flow system is achieved and the internal shape of the tubular multi-chamber core (4) can direct an air stream to flow around all its internal surfaces, which prevents the tubular multi-chamber core walls from overheating, at the same time, air used in later thermal processes of liquid heating can be heated as well.
