Definitions

  • the invention relates to a cylindrical fire grate with a continuous Ash removal for solid fuels, especially for wood chips, wood pellets, granular biogenic fuels (e.g. grain), but also coal and Coke.
  • grates consist of two superimposed Plates exist. With large openings in the mutually movable Panels are perforated. Depending on the position of the two plates the openings are shifted towards each other and thus closed or reduced to a small opening for the necessary air passage or congruent and therefore fully open for the ashes to fall through.
  • the object of the invention was therefore to provide a grate for burners for solid Provide fuels with continuous ash removal and Cleaning the grate openings uniform conditions for a Fire control with high efficiency and low pollutant emissions guaranteed.
  • Another object of the invention is to make larger non-flammable Automatically remove foreign objects from the combustion chamber.
  • the invention therefore relates to a grate for burners for solid fuels, characterized in that it consists of a rotatably mounted, cylindrical grate roller (1) with several circumferential grooves and in each Groove engaging scraper (3), the grate roller (1) by a grate drive (4) in slow continuous or intermittent, slow rotation is transferred.
  • Fig.1 shows the grate construction according to the invention in cross section to Stainless axle.
  • Fig.2 shows the section through the plane A-A of Fig. 1.
  • FIG 3 shows a variant of the grate roller according to the invention.
  • 1 denotes the grate roller with the circumferential grooves
  • 2 the grate shaft 3 the scraper
  • 4 the grate drive 5 the partition shown as a flap
  • 6 the flap shaft 7 the flap drive
  • 8 a screw conveyor for loading the combustion chamber, 9 the combustion chamber, 10 the ash room.
  • the grate according to the invention essentially consists of a grate roller (1) a scraper (3) and constructive measures to discharge larger, non-flammable foreign bodies.
  • the grate roller (1) the Shell surface with circumferential grooves is formed as a grate surface rotates continuously or intermittently around its cylinder axis.
  • the grate roller can either consist of a full cylinder or as a tube be trained.
  • the depth of the circumferential grooves are corresponding to that Size of the grate dimensioned accordingly deep.
  • the width of the grooves is in Depending on the grain size of the fuel selected.
  • Form and type of symbolically represented grate drive (4) can freely according to the Framework conditions of the overall construction can be selected.
  • This grate roller is normally between the combustion chamber (9) and the ash chamber (10) built-in.
  • a wiper (3) engages in the circumferential grooves of the grate roller stuck ash or slag shears off. This can either be as if drawn, but also on any other Place in the lower circumferential area of the grate.
  • Incombustible foreign bodies from the combustion chamber can either be the grate roller lowered downwards so that at the burnout end of the grate fire surface a gap between the grate roller (1) and the partition (5) to the ash room (10) itself opens or the partition (5) can be made movable, e.g. of the Grate surface can be pulled away or swung away.
  • the partition (5) as a flap shown rotatably mounted with the valve shaft (6).
  • Form and type of symbolically represented flap drive (7) or the drive for Lowering the grate can be done freely according to the general conditions of the Application can be selected, either manually or with a drive controlled by the combustion control. Pressing is also possible Spring, so that when a certain force is exceeded the gap between roller grate (1) and partition (5) opens.
  • the automatic loading shown in Fig.1 with a stoker screw (8) is one of the possible forms of loading. It is irrelevant whether the Combustion chamber (3) as shown by means of a screw directly above the Grate roller or loaded from above or is loaded by hand.
  • FIG 3 shows a variant of the grate roller according to the invention.
  • This is hollow in the core as a thick-walled tube on spokes, with circumferential grooves, the depth of which is less than the tube wall thickness.
  • FIG. 4 is a variant of the grate roller according to the invention shown. This is hollow in the core and the circumferential grooves are slits pierced through the lateral surface into the cavity. The ashes will then discharged through the grate interior.
