Definitions

  • the invention relates to a water-cooled Combustion grate.
  • a water-cooled Combustion grate is from document WO-A-9 629 544 is already known.
  • Solid lump fuels e.g. coal, peat, Wood waste and garbage can be burned in a grate in order to generate steam and to waste if necessary remove.
  • the grate is in the combustion chamber either arranged horizontally or at an angle.
  • the grate consists of Grate bars or grate plates, in or between them Rust slots are arranged. They are fixed and movable gratings known. With the movable grates they are Grate bars or plates arranged on routing rollers, or they form an endless, moving band, or they become moved by vibration. The fuel gets in shape of the grate abandoned one shift.
  • the Fuel under the influence of gravity and / or Vibration of the grate bars or the rotation of the grate rollers or the rate of migration of the rust belt through the Combustion chamber transported, with the Combustion air burns.
  • the combustion air becomes the Fuel layer supplied from below through the grate slots (Primary air), where it is possible the fuel layer Part of the combustion air should also be supplied from above (Secondary air).
  • the temperature can be found on the surface of the Rust bars and plates during combustion and values between 650 and 950 ° C, especially during ignition reach, so that cooling of the grate is necessary which is usually done by the combustion air.
  • From DE-PS 312 287 is a hollow grate cooled with water known with interchangeable rods, in which the hollow grate rods have recesses at their ends, in which the with Flow channels provided connectors and those with Pipe connections provided connectors Pressure devices are attached.
  • the connectors generally connect two grate bars in such a way that the all rust, so to speak, a continuous pipe coil forms.
  • the coolant flow can vary depending on the arrangement any of the connectors provided with pipe connections can be designed, and each individual grate bar can be designed according to the Loosen only two connectors to be replaced.
  • This Construction has the disadvantage that the connectors and abutments partly in the immediate vicinity of the combustion chamber and are therefore subject to constant wear. In addition, due to the large distance between the grate bars low air-side rust resistance that generates the Burning process adversely affected.
  • DE-PS 340 602 is a hollow grate with water circulation known, which has additional air channels that the Distribute combustion air over the grate surface, the Additional air ducts through the jacket of one grate on its full-length water chamber are formed and below the widened head of the water chamber in the Open fire chamber.
  • the cooling medium flows through the water Hollow grate bars of the known grate, the grate slots Make incisions in the grate bar around which this is in the hollow bars water is running around.
  • the circulating water is through a corresponding line with a feed water vessel connected. By heating the water circulating in the hollow grate the rust is protected and at the same time the water cooling of the Grate made usable for heating the feed water.
  • This known combustion grate has the disadvantage that it is stationary and only operated with low-ash fuels can be.
  • DE-AS 1 053 131 discloses a grate with divided grate bars that flowed through by the water Pipes rest, between which they are inserted from above and against with a recess corresponding to the tubular profile be pressed.
  • This grate has the disadvantage that it is technically complex; he can technically carried out more simply using jacket pipe walls become.
  • Thrust combustion grate module for burning waste in Large plants known
  • the several movable against each other Has rust levels and a primary air supply, its load-bearing elements and its rust made of hollow sheet metal consist of a liquid in the installed state Coolant are flowed through.
  • the individual grate levels exist each from a hollow grate plate, the length of which is intended to cover the entire width of the To extend combustion grate.
  • the grate plate is inside hollow and has at least one connecting piece and one Discharge nozzle for the supply and discharge of the cooling medium.
  • a pipe below the grate extends the entire length of the grate, which acts as a cooling water supply serves and from the hose connections to each grate plate or rust level or their cooling chambers, and that Hose connections exist that are separate Cooling water returns from each grate plate or grate level or whose cooling chambers to the controls for Return cooling medium control.
  • the primary air is through Holes which penetrate the grate plates.
  • the invention has for its object to provide a water-cooled combustion grate that allows a high thermal load of 0.9 to 1.1 MW / m 2 grate area, has little wear and requires little maintenance.

  • the temperature on the grate bar surface is 90 to 110 ° C. This results in a reduction in wear on the grate and a high thermal load capacity of 0.9 to 1.1 MW / m 2 grate area. This has the consequence that the grate according to the invention can be built about 30% smaller than the known air-cooled grates with the same thermal output.
  • the meandering design of the channels arranged in the interior of the grate bars, in which the cooling medium flows, and the connecting, inlet and outlet pieces to be used according to the invention cooperate advantageously in such a way that the cooling medium is supplied and removed only from the grate limitation ; the individual grate bar blocks or several grate bar blocks can thus be supplied with the cooling medium by the grate limitation, which increases operational reliability.
  • the connecting pieces advantageously cause grate slots to form between the individual grate bars, which make up a grate bar block, and do not change their width during operation.
  • connection, inlet and outlet pieces a grate remover reach around and are screwed to it and in which the meandering channels of the grate bars over the Connection channels of the connectors connected to each other are. This ensures the dimensional accuracy of the grate bar blocks and increases the operational safety of the combustion grate.
  • the individual grate bar blocks are movable over the grate bar supports and / or that the combustion grate has an inclination angle of 8 up to 11 °.
  • the mobility of the grate bar blocks is reduced the operational safety of the according to the invention designed combustion grate.
  • the invention Combustion grate can, for example, be arranged at an angle Counter-running grate or as an inclined feed grate or be designed as a horizontally arranged feed grate.
  • the grate slots have a width of 1 to 1.5 mm. This Width of the grate slots guarantees that the one on the grate fuel does not fall through the slots and that enough combustion air in the fuel layer reached.
  • the rust slots between two Rust bars are present change with regard to their Do not width during operation, because the connecting pieces fix the individual grate bars so that a Rust slot width of 1 to 1.5 mm reliably maintained becomes.
  • connection between the grate bars and the connectors or Inlet and outlet pieces by a flush cut Contact surfaces of the workpieces and through graphite seals are sealed.
  • the grate bars placed on the connecting, inlet and outlet pieces and through vertical screws with the connection, Inlet and outlet pieces are screwed.
  • the size Contact surface and the screw connection result in a good one Fixation of all workpieces and secure sealing of the Cooling system.
  • the combustion grate according to the invention is followed by a horizontal, air-cooled combustion grate known per se. In this way, a high burnout of the fuel is advantageously achieved, although the thermal load capacity of the air-cooled combustion grate is only 0.5 to 0.8 MW / m 2 grate area.
  • the combustion grate according to the invention is followed by a second, horizontal, water-cooled combustion grate according to the invention, by means of which a high fuel burnout is achieved with a high thermal load capacity of the grate.
  • the afterburning can be improved according to the invention be that at the beginning of the second water fair air-cooled or water-cooled grate nozzles are arranged, via the pulsed combustion air in the Combustion chamber is introduced, the pulsed air can also be preheated.
