Definitions

  • the invention relates to a solid fuel boiler according to the preamble of claim 1.
  • the aim of the invention is to avoid these disadvantages and to propose a solid fuel boiler of the type mentioned, in which it comes before the entry of the fuel gases in the heat exchanger to a substantial separation of the ash components.
  • Such a configuration of the interior of the combustion chamber ensures that essentially two vortices rotating in opposite directions result. This results in a particularly intimate mixing and formation of very considerable turbulence, in particular in the contact region of the two vortices, over the rib, which leads to a very good and homogeneous mixing of the combustion air with the fuel gases produced by the heating of the fuel reservoir above the combustion chamber , This leads to a very good and complete combustion.
  • a structurally very simple solution results from the features of claim 4. It is ensured by the adjoining the rib, curved portions a safe diversion of partial flows of the exhaust gases.
  • the door also provides easy access to the combustion chamber for maintenance and cleaning.
  • the ash which preferably deposits in the vicinity of the deflection can be easily removed.
  • FIG. 1 schematically a partially cut solid fuel boiler according to the invention
  • Fig. 2 an axonometric view of a combustion chamber of the boiler according to Fig. 1
  • Fig. 3 a front view of the combustion chamber according to Fig. 2
  • Fig. 4 a section through the combustion chamber along the line IV-IV in Fig. 3
  • Fig. 5 an axonometric representation of a deflection in the outlet of the combustion chamber
  • Fig. 6 an axonometric representation of a fuel gas guide
  • Fig. 7 a plan view of the fuel gas duct
  • Fig. 8 a section along the line VIII-VIII in Fig. 7 ,
  • a frame 1 is provided, in which a water jacket 2 with an inlet 3 and a drain 4 is arranged.
  • This water jacket 2 extends over the region near the flue gas outlet 6 and the ceiling region of the frame 1 up to a refill opening 7 for the fuel, in particular wooden logs 8, wherein the opening 7 is closable with a door 5 which is provided with a heat insulation 7 on its inside 'is provided.
  • an air chamber 9 is provided below the opening 7, which is bounded by a pre-hung in front of a wall 11 of the frame 1 multi-folded sheet 10.
  • the lower wall of the sheet 10 is perforated and allows the access of air.
  • the fuel supply 8 is held in a Kraftstoffvorrats- or gasification chamber 12, inter alia, of the inner wall 13 of the Water jacket 2 and frame walls and down through a nozzle block 14 and a surrounding jacket stone 15 is limited, the remaining space between these is covered against the gasification chamber 12.
  • the casing brick 15 has passages 16 which produce a connection of the space 17 remaining between the casing brick 15 and the nozzle brick 14 with the air chamber 9.
  • the Laval nozzle 18 of the nozzle block 14 connects the carburetor chamber 12 with the interior of a combustion chamber 19, which is arranged in a flame tube 20, whose one end is formed by the wall 13 of the water jacket.
  • the wall 13 is penetrated in its sloping rearward region 21 of flue pipes 23, which open into an exhaust gas chamber 22, from which the flue gas outlet 6 leads away.
  • flue pipes 23 are flowed through by the hot exhaust gases and heat the water in the water jacket. 2
  • the combustion chamber 19 has on its upper side an inlet opening 24 corresponding to the Laval nozzle 18 and an outlet opening 25 facing the front wall of the frame.
  • a deflection device in the form of a baffle plate 26 is arranged, which divides the exhaust gas stream and directs it around the combustion chamber 19 against the wall 13 of the water jacket 2.
  • a fuel gas guide 27 leads away, which establishes a connection with the gasification chamber 12, which communicates via passages in the wall 11 with the air chamber 9.
  • the fuel is supplied with hot exhaust gases and thus brought to outgassing, the resulting fuel gases via the Laval nozzle 18 with the admixture of primary air from the air chamber 9 into the interior of the combustion chamber 19 and burn there.
  • the combustion chamber 19 is based on the Fig. 2 to 4 , the deflection device 26 based on the Fig. 5 and the nozzle block 14 on the basis of Fig. 6 to 8 explained in more detail.
  • the combustion chamber 19 is made of a monolith of refractory ceramic and has in its upper wall a in the longitudinal direction of the combustion chamber 19 extending inlet opening 24, which corresponds to the outlet opening of the Laval nozzle 18 of the nozzle block 14.
  • the interior of the combustion chamber 19 has a rib 28 which extends in the longitudinal direction of the combustion chamber 19 and is formed by the intersection of two partial cross sections 29, 30 with curved boundary lines, so that a "double-bubble" cross-section results.
  • the combustion chamber 19 is provided with feet 31, 31 ', 32, with which the combustion chamber 19 rests on the lower boundary of the flame tube 20. This limits the heat removal from the combustion chamber.
  • the combustion chamber 19 Since the combustion chamber 19 has a substantially equal wall thickness, the free cross section between the outside of the combustion chamber 19 and the inner wall of the flame tube 20 increases towards the wall 13 of the water jacket 2. This results in a very significant reduction in the flow velocity of the exhaust gases due to the increasing flow cross-section, which precipitate ash.
  • the deflection device which passes through the deflection plate 26 (FIG. Fig. 5 ) is formed, has a substantially vertical rib 33, which is formed by an overlap of two substantially Zylindermantelfab Songs corresponding surfaces 34, 35. These surfaces 34, 35 are incorporated in a plate which is held by means of anchor bolts 36 having a heat-insulating layer 38 (FIG. Fig. 1 ) and anchored in a door 37.
  • the exiting from the combustion chamber 19 exhaust gases are divided by the rib 33 in two parts and led around the combustion chamber 19, wherein the free cross section between the outside of the combustion chamber 19 and the inner walls of the flame tube 20 increases against the wall 13 of the water jacket 2.
  • the nozzle block 14 has, as from the Fig. 6 to 8 can be seen, an elongated inlet opening 39 of an opening, which is designed as a Laval nozzle 18.
  • the inlet opening 39 is strongly rounded over its entire circumference.
  • the Laval nozzle 18 has near the inlet opening 39 a constriction 40, to which - seen in the flow direction - an expanding region 41 connects, which ends in an outlet opening 42.
