Definitions

  • the invention relates to a boiler with a burner for solid fuels, consisting of a filling shaft, a fuel gas and combustion air guide frame, a burn-through grate and an adjoining cyclone combustion chamber and an exhaust gas duct.
  • boilers of this type place high demands on the form of fuel and, on the other hand, they can only be used economically to a limited extent.
  • combustion air supply which is unfavorable for combustion, poorly designed combustion chambers or unfavorable aerodynamic conditions in the combustion chambers.
  • the object of the present invention is to design a boiler and in particular a burner for solid fuels of the type defined in the introduction such that the heating value of solid fuels can be used with a high degree of efficiency and with respect for the environment in spite of low manufacturing outlay.
  • combustion chamber designed as a cyclone combustion chamber, in which the gases rotate in the direction of an outlet opening rotating about the longitudinal axis of the chamber, these gases can burn out completely with a long dwell time and thorough mixing. These burned-out and hot gases leave the outlet opening and enter a laterally arranged exhaust gas guide chamber. It is essential that even such small-sized fuels as briquettes or coarse wood chips can or can be used with such a burner design. For assembly and repair purposes, it is important that the burner can be installed in the boiler and replaced if necessary, without the use of special tools and binders such as mortar.
  • the boiler itself can be made of either steel or cast iron, with a large filling shaft being possible without any problems.
  • the combustion chamber in which a comparatively long residence time of the combustion gases can be guaranteed at a flame speed that is not too high and therefore not at too high temperatures, is isolated from the water-carrying parts of the boiler and the firing grate by a brick lining.
  • the lateral flue gas routing enables long paths and large heating surfaces to be realized, it being possible to increase the resistance of the flue gas path by extending baffles that are easily accessible from the front of the boiler via corresponding openings, or to reduce them by shortening the plates.
  • the arrangement of all operating and maintenance openings on the front of the boiler makes it easier Cleaning and operation, the heating surfaces in particular being easily accessible for cleaning.
  • a fuel gas and combustion air guide frame 1 with a primary air duct 2 with longitudinally adjacent outlet openings 8, a secondary air duct 3 arranged underneath with nozzle-shaped outlet openings 6, which open out on both sides of a burn-through grate 4 which runs out from the top of a cyclone combustion chamber 6 refractory material is arranged, which has an outlet opening 7.
  • This outlet opening 7 is preferably provided at the end of the combustion chamber 5 opposite the fuel gas supply.
  • the burn-through grate 4 is held removably in the combustion air guide frame 1 and, as FIG. 2 shows, has a plurality of grate bars or webs lying next to one another.
  • the width of the burn-through grate 4 preferably corresponds to approximately half the combustion chamber width, and this burn-through grate extends in the longitudinal direction of the combustion chamber over a third to over half the combustion chamber length.
  • this information is not restrictive.
  • the sectional view according to FIG. 3 shows that the primary air duct 2 and the secondary air duct 3 extend essentially over the entire length of the combustion chamber, the outlet openings 8 of the primary air duct 2 preferably being arranged uniformly distributed over its length.
  • Fig. 4 shows a variant of the burner according to Fig. 1, in which case the secondary air duct 3 has an approximately rectangular shape throughout and the burn-through grate 4 is held in a recess of the secondary air duct 3, the outlet openings 6 being formed in the walls of this recess.
  • FIG. 5 shows an overall perspective view of the boiler according to the invention using a burner as shown schematically in FIG. 1.
  • FIG. 6 again shows the boiler according to FIG. 5, but the side wall is cut open in such a way that the exhaust gas guide chamber 10 arranged on the side is visible in detail.
  • the plates 11 causing the deflection of the exhaust gases are arranged at least essentially horizontally and are easily accessible via openings provided on the end face.
  • the resistance of the exhaust gas path can be increased by lengthening the deflection plates 11 or reduced by shortening these plates. All heating surfaces are well original for cleaning. It can also be seen in the diagrams according to FIGS. 5 and 6 that the combustion chamber is well insulated from the water-carrying parts of the boiler and also from the combustion air guide frame by the lining.
