Definitions

  • the invention relates to a solid fuel boiler according to the preamble of independent claim 1.
  • a solid fuel boiler of the type mentioned is according to AT 005 583 U1 known, the combustion chamber is not located in a water-bearing housing, that is, only the exhaust pipes are water cooled and provide as sibling unit the actual heat exchanger of this boiler, in a necessarily provided with, however, not shown, flow and return ports housing.
  • a completely different from the construction principle of the aforementioned solid fuel boiler solid fuel boilers is also after the AT 501 374 B1 known, to which reference is drawn for the sake of completeness.
  • a directly leading to the exhaust gas connection exhaust duct divided from the combustion chamber space which is penetrated by water-carrying heat exchange tubes.
  • baffles are incorporated in the water-conducting double jacket of the housing, which should ensure that the supply pipe for the solid fuel with the relatively cold return is washed around.
  • the invention has for its object to improve such a boiler in terms of heat yield, combined with the proviso at the same time to ensure that the solid fuel boiler with sliding boiler temperature of ⁇ 38 ° C is operable without the dew point temperature of the waste or hot gases below.
  • the invention is also based on the object to improve the return of the heat transfer medium from the return port to the outer flow zone in a boiler of this type, in particular under flow and manufacturing aspects.
  • the combustion chamber is at least partially enclosed along its vertical extension and relative to its circumference by an inner and an outer flow zone for the heat transfer medium, that the flow zones at least at one end connected to each other and through a along the Combustion wall extending partition wall are separated from each other, and that the inner flow zone with the flow connection and the outer flow zone with the return port is fluidly connected, and that the return port provided with a plurality of directed into the outer flow zone outflow, arranged at an end edge of the partition wall and tubular Return manifold is connected.
  • a partition wall is arranged, which comprises the combustion chamber at least partially with a certain distance, wherein the partition wall, the first, inner, associated with the flow connection, the combustion chamber immediately adjacent flow zone and the second, outer, now the partition wall flow zone defined, wherein at one end of the partition a return flow in the second outer flow zone directing here so-called return manifold is arranged.
  • the partition wall extends substantially over the entire height of the combustion chamber and its lower and upper end edges extend horizontally in the housing.
  • An essential feature is in addition to the direct Be Hughesung the combustion chamber wall with the inner flow zone of the heat transfer medium and the design of the return line, ie, with respect to the vertical combustion chamber wall is ensured that it is largely surrounded by the inner flow zone and separated by the partition, an outer cold zone is present, in which the cold return water through the appropriately designed and arranged return manifold specifically introduced and thus kept away from the wall of the combustion chamber. A direct loading of the combustion chamber wall with cold return is thus prevented, and also it is sufficient for the condensation and corrosion protection requirements.
  • the return manifold is arranged at the upper end of the partition and thus the return passes from above into the outer cold zone, in which the cold return flows down, there in the hot zone flows over and flows upwards in this along the combustion chamber wall.
  • the invention differs so far substantially, as the solid combustion chamber itself is surrounded in an advantageous, preferred and yet to be explained embodiment with an articulated into two flow zones water or heat carrier guide and the return flow is directed into the outer flow zone.
  • the combustion chamber, the partition, the receiving housing, and ultimately also the return manifold in horizontal section or in plan view are preferably also circular or circular arc-shaped in consideration of a uniform distribution.
  • the heating gases to the exhaust port laxative, arranged parallel to the combustion chamber heat exchanger is arranged in a water-leading extension of the housing and stands on the inflow side with the upper part of the combustion chamber in connection, in the exhaust gases in Walkergaszugrohren leading heat exchanger the Schugaszugrohre in the sense of the aforementioned AT 005 583 are arranged in two oppositely flowed through groups.
  • the heat exchanger are arranged in relation to the circular cross-section of the combustion chamber in an area of the order of one quadrant, which will be explained in more detail.
  • the solid fuel boiler consists of a water-bearing housing 1 with in FIG. 1 only indicated by dashed lines flow and return ports 2, 3 and from a below a vertically oriented in the housing 1 combustion chamber 4 arranged burner 5 with primary and secondary air supply 6, 7 (see FIG. 1 ) and with a fuel supply 8, wherein the combustion chamber 4 is connected by an outgoing hot gases leading heat exchanger 9 with an exhaust port 10.
  • the fuel supply 8 consists of a suitable pellet silo with feed device (not shown) for the pellets in the burner 5. Such devices are known and therefore require no further explanation.
  • a whole arranged under the burner 5 ash collection room 28 belongs to the whole.
  • a combustion chamber 4 receiving part 1.1 of the housing 1 is also designed to carry water and that to form a first with respect to the combustion chamber 4, internal, with the flow connection 2 in communication flow zone 12 and a second, outer flow zone 13 in the water Part 1.1 of the housing 1 is a substantially over the height H of the combustion chamber 4 extending, horizontally extending end edges 11.1, 11.2 having partition wall 11 is arranged, and that at one of the end edges 11.1, 11.2 of the partition 11 a over the length of the end edges 11.1, 11.2 extended, connected to the return port 3 return manifold 15 is arranged, the return outflow 14 is preferably directed over its entire length in the second, outer flow zone 13.
  • the partition wall 11 has therefore to be imagined as a thin shell of suitable material arranged in the intermediate space between the combustion chamber 4 and the wall 1.2 of the housing 1. Since the initiated return flow into the outer flow zone 13 takes place deliberately, the two zones 12, 13 do not require a sharp separation at their ends 12.1.
  • the proviso that the partition wall 11 comprises the combustion chamber 4 at least partially, takes on the preferred, in the Figures 2 . 3 illustrated embodiment of the solid fuel boiler consideration, namely in the laxative the exhaust gases to the exhaust port 10, parallel to the combustion chamber 4 arranged heat exchanger 9 in a water-bearing extension 1.4 (see, in particular Figures 2 . 3 ) of the housing 1 and on the inflow side with the upper part of the combustion chamber 4 is in communication.
  • the preferred embodiment also includes that the return manifold 15 at the upper end edge 11.2 (see FIGS. 1 and 4 ) of the partition wall 11 is arranged.
  • the flow-through scheme for this preferred embodiment is in FIG FIG.
  • FIG. 1 shown in dashed lines, the exhaust gases and the heat transfer medium leading, the solid fuel boiler downstream heat exchanger is a preferred embodiment. In principle, however, of course, any suitable heat exchanger into consideration, ie the invention is not limited to the illustrated embodiment
  • the partition wall 11 and the housing 1 accommodating these in the horizontal section are advantageously circular, wherein the Figures 2 . 3 also reveal the resulting circular arc shape of the return manifold 15.
  • FIGS. 1 to 3 With indicated, leading to the burner 5 fuel supply is denoted by 8, for their passage through the water-bearing interior 26 a facing 29 (see FIG. 1 ).
  • the partition wall 11 has a corresponding cutout in the pass-through area.
  • the hot gases flowing out of the combustion chamber 4 pass through a hot gas overflow opening 27 (see FIG Figures 2 . 3 ) first into the part 22.1 of an overflow chamber 22, from there into the first group 17 of Bankgaszugrohre 16, then via the second group 17.1 in the second, separated by an intermediate wall 23 part 22.2 of the overflow chamber 22 and then pull off through the exhaust port 10.
  • the first group 17 of Bankgaszugrohre 16 thus forms a discharge part 24 and the second group 17.1 a Aufströmteil 25 of the heat exchanger 9.
  • the overflow chamber 22 is located at a combustion chamber closure 30 sealed up combustion chamber 4, lapped by the heat transfer medium, in the upper part of the extension of 1.4 ,
