Definitions

  • the invention described here is a fired heat exchanger designed to be best used in boilers and pre-heaters.
  • EP-A-1 184 628 disclosed a heat exchanger which has a row of plates forming hollow chambers for a heating medium and intermediate chambers for a heating gas flue.
  • the plates form a modular body with integrated chamber for a burner. Heating medium chambers and heating gas chambers alternate with each other. One plate has flow surfaces for the heating gas and the other one has flow surfaces for the heating medium.
  • a fired heat exchanger comprising a modular block of panel plates connected inseparably together, whereas each panel plate is made of two plate members connected inseparably one with another and creating in one side a combustion chamber and in its other side is integrated with a working heat exchange surface for hot gases, said heat exchange is created by a surface of one of the plate members together with protrusions is characterized in that the combustion chamber is in the upper part of the plate members and is surrounded in its upper side with a water jacket and in its lower side integrated with the working heat exchange surface, said heat exchange surface has creased bands mounted thereon, and the circulation of the liquid heated medium in the unit of panel plates has a medium flow velocity within the range 0.5 - 2 m/s and is of a two stage - type, wherein during the first stage, the main process of heat exchange on the working surface takes palace and during the second stage the combustion chamber is cooled by the water jacket.
  • This layout ensures full integration of the combustion chamber with the working heat exchange surface located in the lower part of the panel plates.
  • the working heat exchange surface is created by the lower lateral sides of the panel plates and the creased bands mounted on them.
  • the bands expand the working heat exchange surface and the gasses created in the combustion chamber flow around this surface.
  • the circulation of the liquid heated medium in the unit of interconnected panel plates has a flow velocity of the medium within the range of 0.5 - 2 m/s and is of a two-stage type. During the first stage, the main process of heat exchange on the working surface takes place. During the second stage, the combustion chamber is cooled by the water jacket, constituting the upper part of panel plates.
  • the structure of the fired heat exchanger ensures full integration of the combustion chamber with the working heat exchange surface, which provides effective cooling for the combustion chamber and a sample compact build obviating the need for additional closing elements.
  • High thermal efficiency has been achieved by means of specially shaped creased bands filling the space between panel plates expanding the working heat exchange surface, which provides the possibility for combustion product condensation and turbulence.
  • the vital advantage of this solution is the high heat exchange surface to weight ratio.
  • This new invention facilitates power scaling by adding or removing additional panel plates and utilising a condensation technique enabling the unit to use less fuel and emit smaller amounts of detrimental compounds to the air. Thanks to this, the device is ecologically efficient. Another important advantage of this solution is the simplified production technology with the possibility of using full automation.
  • Fig.1 shows the perspective view of the fired heat exchanger with a partial pre-installation setting-up of the heat exchanger part
  • Fig. 2 shows the perspective view of the heat exchanger elements set which, having been connected, create a panel plate together with a creased band mounted on the lateral surface
  • Fig. 3 shows the axonometric view of the panel plate together with the creased band.
  • the invented fired heat exchanger described in this document contains a modular block constituting a set of inseparably interconnected panel plates 1 with a combustion chamber water jacket 4 located in its upper part and the working heat exchange surface in the lower part. These surfaces create the lower lateral surfaces 5 of the panel plates 1 together with the creased bands 3 mounted on them. They expand the working heat exchange surface and the gasses created in the combustion chamber flow around this surface.
  • the circulation of the liquid heated medium in the unit of interconnected panel plates has a flow velocity with a medium within the range 0.5 - 2 m/s. It is two-stage type: during the first stage, the main process of heat exchange on the working surface takes place, while during the second stage, the combustion chamber 2 is cooled by the water jacket 4 constituting the upper part of the panel plates 1.
