Definitions

  • the invention relates to an air-cooled grate covering mounted on cross members for feed grates, particularly in waste incineration plants, two grate bars arranged next to one another each forming a flow channel which is delimited by the grate bar bridges, the grate bar base and its supporting webs and has an outlet to the combustion chamber through recesses arranged in the grate bar head.
  • Such a grate has become known from DE-C-37 25 585.
  • This known grate covering has proven itself well in operational use, but it can happen from time to time during the forward movement of the movable grate bar rows that garbage and / or slag particles penetrate into the air outlets of the grate bars and through the nozzle-shaped design of the air outlets (decreasing cross-section in the air flow direction ) get stuck and are carried along when the movable rows of grate bars move backwards.
  • the invention specified in claim 1 has for its object to provide a grate covering according to the preamble of claim 1, which reduces the risk of clogging of the air outlets.
  • the air outlets are at an angle of up to 60 ° to the bottom of the grate bar, the penetration of garbage and / or slag particles is made more difficult and insofar as this actually occurs, the detachment is usually promoted when the rows of grate bars move backwards.
  • the design of the grate bars for cooling the grate bar and the trouble-free operation of a feed grate for a waste incineration plant has an advantageous effect.
  • the grate bar 1 shown in FIGS. 1 to 7 has the grate bar bridge 6, the grate bar head 3, the grate bar base 9, the web 4, which is provided with lateral edges 8.
  • the chamfered grate bar head 3 is provided with a plurality of recesses 7 and the projections 10 and 11.
  • the grate bars arranged side by side in FIGS. 3 and 4 together form the air guide path 2, which is delimited by the underside of the grate bar bridge 6, the grate bar base 9, the web 4 and the lateral edges 8.
  • the air duct 2 has through the recesses 7 in the side edges 8 of the grate rod heads 3 outlet to the combustion chamber 5th
