Definitions

  • the present invention relates to a grate block as part of a grate for a plant for thermal treatment of waste.
  • the heart of a waste incineration plant is the combustion grate.
  • the waste such as household waste, is transported from one end of the combustion grate to the other end of the combustion grate.
  • the oxygen required for the combustion of the residues is contained in sufficient amount in the air.
  • the air also called primary air, is thereby pressed from below through the combustion grate and thus fed to the firing chamber with the residues to be incinerated.
  • stair grate One type of the various known types of combustion grate is the so-called stair grate.
  • a stair grate comprises juxtaposed and firmly connected grate blocks, which form the individual grate block rows.
  • the successive grate block rows are staggered to each other and lie with their combustion chamber facing the front walls of the grate blocks, which form the grate block rows on each other.
  • Some of the rows of grate blocks, for example every other, are movably arranged. By the lifting movement of this movably arranged grate block rows of the residue is transported to the following in the transport direction grate block row.
  • the residues burned in an incinerator mentioned above are very different.
  • the spectrum ranges from household waste to commercial waste right through to the actual Fuels, such as wood in the form of sawdust, biomass and the like.
  • the calorific value of these residues is, depending on the nature of the residue, naturally very different. However, there are also large fluctuations in the calorific value within a type of residue. These strong fluctuations in the calorific value also result in strong fluctuations in the thermal and mechanical loading of the combustion grate or of the individual grate blocks.
  • the combustion grates or the individual grate blocks can be sufficiently cooled with air (primary air).
  • air primary air
  • combustion grates with water-cooled grate blocks are known from the prior art. Sufficient cooling of the grate blocks is very important, otherwise there is a risk of melting the combustion grate.
  • EP 1 191 282 describes a grate block, which has a cooling space for water on its side facing away from the firebox.
  • EP 1 219 898 discloses a grate block with a cooling element mounted below the support surface for the waste. Again, water is used for cooling.
  • DE 10 2004 032 291 discloses an air-cooled grate plate with below the top of the grate plate is formed a flow channel.
  • combustion grates Although with water cooled grate blocks a means is available that allows the production of efficiently cooled combustion grates, such combustion grates have the disadvantage that both their Production and the subsequent process engineering effort is much higher than in combustion grates, which are composed of air-cooled grate blocks.
  • Object of the present invention is to provide a grate block available that has at least as good wear resistance and thus an equal long life compared to water-cooled grate block and at the same time avoids its disadvantages of high production and process engineering effort.
  • the inventive grate block has the features according to claim 1.
  • the grate block has a block body, which is designed as a cast part.
  • the block body has an upper wall forming a support surface and a front wall to which a foot is formed.
  • the grate block is part of a grate for the thermal treatment of waste.
  • the grate blocks are arranged one above the other like a staircase and the individual grate blocks lie with the formed on the front wall foot on the support surface formed by the upper wall of the subsequent grate block (staircase).
  • the waste to be treated thermally also rests on this bearing surface formed by the upper wall.
  • the rust may have a tendency.
  • This inclination is in a range of 0 ° to 26 °, preferably in the range of 10 ° to 18 ° relative to an imaginary horizontal plane.
  • a wall inlet On a bottom of the upper wall is a wall inlet arranged. This wall inlet lies on the side of the upper wall facing away from the firebox.
  • a first cooling channel section extends through the upper wall and the front wall to an outlet opening arranged in the front wall. Adjacent to the front wall and the foot formed thereon, an inlet opening is arranged. From the inlet opening is a cooling passage wall, which is spaced from the front wall and the upper wall, and forms at the wall inlet with the first cooling passage portion fluidly connected second cooling passage portion.
  • the first cooling channel section and the second cooling channel section together form a cooling channel, which shows a substantially S-shaped profile in longitudinal section.
  • the cross-section or the cross-sectional area of the first cooling passage section and of the second cooling passage section-and thus of the substantially S-shaped cooling passage- is constant in the simplest embodiment.
  • the cross section can also vary.
  • the grate block according to the invention allows the use of gaseous cooling media, in particular air, even in the thermal treatment of residues with a higher calorific value (> 10MJ / kg). Water cooling, which is often required for higher calorific value residues, is eliminated.
  • the grate block according to the invention makes possible an excellent and differentiated cooling of those points of the grate block which are thermally exposed to the greatest loads. This is very advantageous because, in the case of cooling with air, the primary air available for cooling is limited. Furthermore, the primary air used for cooling is around 120 ° C heated to 150 ° C, which is why it can be dispensed with (previously required) preheating the primary air.
  • the grate block according to the invention achieves excellent, ie long, service lives which are comparable to the service lives of water-cooled grate blocks.
  • first cooling passage section and the second cooling passage section have a varying cross-section.
  • cross-section the cross-sectional area of the first and second cooling channel section is designated.
  • the shape of the cross-sectional area may be different. Possible cross-sectional shapes are rectangular, quadrangular, polygonal, e.g. a flattened hexagon, circular or oval.
  • the heat removal of the gaseous cooling medium denotes the amount of heat dissipated by the cooling medium per time.
  • the heat dissipation depends inter alia on the flow velocity of the cooling medium relative to its surroundings, in the present case of the first and the second cooling channel section. It is greater, the higher the flow velocity of the cooling medium.
  • the cross-sectional area can be smaller or larger.
  • the flow velocity of a gaseous cooling medium preferably the primary air
  • increases which results Increased heat removal by the gaseous cooling medium leads to higher cooling.
  • Increased heat removal means that the gaseous cooling medium absorbs a larger amount of heat from its surroundings and, due to the increased flow velocity due to the reduced cross-sectional area, dissipates it.
  • the cooling can be tailored to the particular thermal load of the individual grate block area.
  • the front wall of the grate block can be specifically intensified cooled.
  • the flow velocity of the gaseous cooling medium e.g. the primary air
  • the heat dissipation achieved This makes it possible to work with a limited amount of cooling medium, e.g. Primary air to cool even less thermally stressed areas of the grate block, whereby the cooling is improved overall.

  • the direction L corresponds to the conveying direction of the waste in the longitudinal direction of the grate.
  • the waste passes through different zones, starting with the drying zone at the end of the grate over the combustion zone up to the burn-out zone at the other end of the grate opposite the drying zone.
