Definitions

  • the invention relates to a grate furnace with a Grate constructed of adjacent grate elements Rostton, of which in each case every second rust step in Rostlhackscardi drivable for performing Schürzien and the intervening rust steps fixed are, wherein the driving devices for the movable Grate levels are located below the grate.
  • the object of the invention is to provide a grate firing, the both a simple and against rust diarrhea protected arrangement of the drives under the grate, as well as a replacement of the drive devices during of ongoing operation allowed.
  • the drive devices Protected against everything, from above through through the rust can get into the underwinding chamber.
  • each drive device a separate housing chamber provided, the one Assembly or replacement of the drive device during of ongoing operations.
  • each Housing is thermally insulated. This proves in particular then as beneficial if the on the housing in the underwinding chamber Preheating primary air preheated very strongly becomes. To the effect achieved by the thermal insulation is still to reinforce, can in development of the invention be provided for each case a forced ventilation.
  • the use of a push rod between a guide guided slide and the Piston rod of the drive cylinder has the advantage that the especially finely machined surface of the piston rod always remains in the protective housing, so that the danger Damage to the seal of the working cylinder Impairment of the piston rod is not given. damage the seal on the housing caused by deposits can occur on the push rod, then have no serious Follow the same instructions as damage the seal of the working cylinder can occur.
  • the invention provided that the piston rod connected to the push rod by a hinge.
  • a grate firing according to FIG. 1 comprises a feeding hopper 1, one over a feed table 2 reciprocable Feed device 3, a grate 4, one at the end of Grate arranged stowage device 5 for damming the Slag and a slag chute 6, in which the burnt out Slag falls into it.
  • Underwind chambers 7.1, 7.2, 7.3 and 7.4 are below the grate 4 and four separate Underwind chambers 7.1, 7.2, 7.3 and 7.4. These underwind chambers each have connections 8.1 to 8.4 for the separate supply of primary air from the bottom is blown against the grate 4 and through it in the fuel lying on the grate, for example garbage, arrives.
  • the underwind chambers are staggered in relation to each other arranged following the inclined grate 4.
  • a carriage 9.1 to 9.4 arranged which, as can be seen in particular in connection with FIG. 3, is provided with two pairs of rollers 10 and 11, the are guided in guideways 12.
  • Carrier 13 and 14 On every sled are Carrier 13 and 14 arranged, each of which driver each with a movable grate level 15 and 16 into engagement stands.
  • the firing grate is made of alternately movable and fixed grate steps constructed, with between two movable grate stages 15 and 16 a fixed one Grate stage 17 is provided.
  • a slide 9 is therefore for provided the movement drive of two movable grate stages.
  • the guideways 12 are parallel to the direction of movement the movable grate stages 15 and 16 aligned.
  • each carriage 9 and the associated Grate levels 15 and 16 serves a total of 18 designated drive device, which has a working cylinder 19, one movable in the cylinder and in the drawing Not shown piston and a piston rod 20 includes.
  • the working cylinder 19 is by means of a hinge assembly 21st attached to a cross member 22, while the piston rod 20 connected via a hinge 23 with a push rod 24 is to be described by a seal 35 of a yet to be described Housing engages.
  • any drive device except the drive device 18.4, which for the drive of the last two moving Rost stages just before the slag chute serves are in a coherent in the embodiment housing 25, which is divided into housing chambers, the are consecutively designated 25.2 to 25.4.
  • housing chambers 25, which can be seen in particular from Figures 2 and 3 are protective surrounding the drive devices 18.1, 18.2 and 18.3.
  • the drive assembly 18.4 is located below an inlet funnel 26 for the slag chute 6 and thus lies outside the grate area, which is why no housing chamber is provided for this drive ..
  • the respective housings 25 are, as shown in FIGS. 2 and 3 seen, streamlined and designed and arranged, that in each case between the inner wall 33 of an underwinding chamber 7 and the outer wall 34 of the housing 25 a in the substantially constant flow cross section 32nd remains.
