Definitions

  • the invention relates to a sectional boiler, in particular a condensing boiler made of cast iron or aluminum materials, according to the preamble of claim 1.
  • Such sectional boiler consist of several integrally cast boiler members, which are arranged one behind the other and water side connected by hubs.
  • the water channels and pockets formed by the boiler members are flowed through between the return connection and the supply connection.
  • generic sectional heating boilers have a lower return connection and a top feed connection, preferably in the respective hub.
  • the hot gases flow from the combustion chamber via downstream hot gas flues to an exhaust gas outlet and release heat to the boiler water on their way.
  • the links are arranged in series one behind the other.
  • the combustion chamber extends through the front and middle links to the rear link, which forms the bottom of the combustion chamber with its lid-shaped design.
  • All of the boiler members have similar external dimensions in these embodiments because they form parts of the combustion chamber, Schugastecn and water space over the entire boiler cross-section.
  • boilers for low power ranges are known, which consist of only two or even only one boiler member.
  • heating value technology With regard to the exhaust system and the efficiency of the heaters, a distinction is made between heating value technology and condensing boiler technology. For reasons of energy saving more and more condensing boilers are used.
  • the design of their heat exchanger provides the opportunity to cool the resulting in the combustion of fuel and air moist exhaust gases below the Abgastauddling. The moisture of the exhaust gases condenses and in addition to the sensible heat, the heat of condensation is transferred to the heating water.
  • the heat exchangers of conventional calorifiers are often made of cast iron. They are characterized by high robustness and long life. Their construction of mostly identical casting segments allows cost-effective production and easy scalability with regard to different output sizes and offers good mounting options even under tight installation conditions. The material endures the short exhaust gas condensation phases very well at startup and cold heat exchanger. Only for condensing operation with a prolonged accumulation of condensation is cast iron in its present form and design not suitable.
  • a sectional boiler according to the preamble of claim 1 is known from the disclosure of the document DE 10 2008 013 086 A1 known.
  • the invention has the object to optimize a sectional boiler made of cast iron or aluminum, in particular with regard to compactness and robustness.
  • the sectional boiler is characterized in that the heat exchanger has as heating flues in each case annular gaps between two adjacent members with an associated geometry, each extending from the combustion chamber approximately radially outwards and open into an exhaust gas collecting space on the outside of the links.
  • the individual members are flowed through serially on the heating water side, wherein the return water first enters the rear link via the return connection. Then, an overflow into an adjacent member in the region of the upper hubs, because the lower hubs are sealed from each other.
  • sealing means are provided for heating water-side sealing of the lower hubs against each other in the direct area of the respective hubs or between the hubs of two adjacent links.
  • sealing washers can be inserted in the joints.
  • the links are each hydraulically provided with overflow openings only at one point on the circumference and connected to these on at least one side with an adjacent member.
  • This overflow serve as a hydraulic connection in the respective adjacent member.
  • at least one flow-guiding means is arranged in the water space, inter alia also for achieving a low pressure loss during the flow deflection.
  • a flow-guiding means preferably exists in the connection region of the water space from a substantially transverse to the water space, approximately vertically aligned with the axis of the connecting portion wall which closes the respective flow channel in a member and the incoming flow from the axial directs in the circumferential direction and the exiting flow from the circumferential in the axial direction adjacent member directs.
  • a flow directing means in the form of a water space transversely dividing, approximately vertically aligned to the axis of the connecting portion wall is arranged at an angle of 30 to 50 degrees obliquely in the respective flow channel of a member.
  • the flow channel is in the region of the upper hub above the overflow and leads the flow of water from the upper region of the front member to the flow connection in the rear member.

  • a corrosion protection coating according to the invention is not only easy to apply and to control, but it is also protected in the gaps from possible mechanical stresses.
  • the sectional construction also offers the advantage of being able to variably cover different lengths for different combustion and heat exchanger capacities by inserting further center elements. Nevertheless, then remain all front-mounted attachments and the water-side connections the same, because all water-side connections are easily accessible on the back, so in the rear member. Only the surrounding cylindrical shell around the exhaust gas collection chamber varies. Because of the low exhaust gas temperatures, this can even be made of plastic.
  • the sectional boiler consists essentially of annular members, namely a front member 1, a ceiling-shaped rear member 2 and a plurality of middle members 3.
