Definitions

  • the invention relates to a power system, in particular, to designs of grates, and can be used in various furnace devices, in particular, in heat generators.
  • a well-known non-woven kolayshshevayaleeshhetka the canvas of which consists of alternating T-shaped and cross-shaped grate-bars, between which there are zigzag slots for the passage of blast air (A.S. 79825, class F23H17 / 12, 01.01.01.49).
  • the curved shape of the grate is made in such a way that they engage each other, creating a single design. This will make it difficult to repair the grate, since to replace, for example, one grate, it will be necessary to remove the entire grate.
  • Known grate furnace grate with a shuruyuyu leveling equipped with lowering and rising using an eccentric grate tiles (A.S. 91770, class. ' F23H9 / 06, op.01.01.51g.).
  • This grate has a complex structural solution. The presence of many moving parts at high temperature in the furnace can cause them to break.
  • a grate containing beam grates installed with the possibility of rotation, and a screwing bar.
  • the design contains water-cooled pipes located between the grates, and made straight or in the form of coils, with the upper generatrix of the pipes located in a plane lying below the working surface of the grate (ac l 520304, Kn.F23H9 / 10, on.07.1 1.87).
  • Availability systems of water-cooled pipes connected to the collectors significantly complicates the design and complicates the repair work.
  • the task of the invention is to develop a grate of a simpler design that provides efficient operation and ease of operation and repair.
  • the screwing gages are made in the form of elements covering the grate grates with recesses on the sides, mounted with the possibility of reciprocating movement on the crank shaft mechanism with eccentrics for each shuruyuschey device with the provision of counter-flow.

  • a grate 2 is installed, having girder grates 3, for example, in the form of cylinders - pipes through which water is supplied through pipes 4, and screwing devices 5, made in the form of elements covering the grate grates 3 - on top of the rigidly fixed grates 3, with recesses on the sides 6.
  • Water for cooling can be connected to the heating system, which will increase heat transfer, and can be independent.
  • the area of the recesses 6 of the screwing device 5 is 15-30% of its total area.

Abstract

L'invention concerne le génie thermique et notamment la conception de grilles de foyer et peut être utilisée dans différents dispositifs à chaudières, notamment dans des générateurs thermiques. Dans la conception d'une grille de foyer possédant des éléments de grille en forme de poutres et des accessoires pour tisonner le feu reliés à un moteur électrique, les accessoires pour tisonner le feu se présentent comme des éléments entourant les éléments de grille en forme de poutres avec des logements sur les cotés montés de manière à permettre un mouvement en va-et-vient avec des excentriques pour chaque accessoire pour tisonner le feu afin de permettre une course en sens inverse. La conception proposée de grille de foyer est plus simple que les structures analogues et permet d'améliorer sensiblement l'exploitation du dispositif et d'assurer des travaux d'entretien.
