Definitions

  • the present invention concerns a grate furnace for alternative fuel, as stated in the introductory part of claim 1.
  • RDF Refuse Derived Fuel
  • a furnace for combustion of RDF operates in a manner where the fuel is supplied at a grate which is located over a primary air chamber, the chamber often being divided in sections.
  • the combustion furnace is divided into a primary chamber and a secondary chamber, where the fuel is combusted in two steps.
  • US-A-3 808 619 discloses an incinerator having a first combustion chamber which receives the waste to be incinerated.
  • An ignition-burner is provided in the first chamber to ignite the waste; the burner automatically turns off at waste incineration temperature.
  • a second combustion chamber is spaced above and communicates with the first chamber. Separators are provided in each chamber for separating partially burned particles from the fully burned combustion gases and preventing the particles from rising beyond the respective separators.
  • An after-burner is arranged to project a substantially horizontal flame into the second combustion chamber; the flame produced by the after-burner substantially filling the cylindrical second chamber and reducing any microscopic particles or unburned gases which have passed through the separators.
  • a grate furnace generally denoted 1, which is divided into a primary chamber 2 and a secondary chamber 3.
  • the primary and secondary chambers 2, 3 are protected by a surrounding insulation 4.
  • a primary air chamber 5 which is divided into a plurality of sections for flexible supply of primary air and recirculated flue gas.
  • a grate 6 adapted for energy-rich fuel (e.g. RDF).
  • the grate 6 is cooled, e.g. by water.
  • the grate is constructed to give a high pressure drop.
  • a guillotine 8 controls the amount of fuel supplied by the feeder 7.
  • the guillotine 8 ensures a good control option for the fuel height above the grate 6, and a stable and even fuel distribution over the entire width of the grate 6.
  • the fuel is supplied from a fuel stock (not shown), by means of a feed screw 9, to a fuel container 18 in the area outside of the guillotine 8.
  • the fuel container 18 is preferably insulated/cooled, so that it does not cause exhaust gas from the fuel to occur.
  • the primary chamber 2 and the secondary chamber 3 are separated by a separating plate 10.
  • the separating plate 10 is movable both in height and lateral direction, in order to vary the volume of the two chambers 2, 3 and furthermore, to direct the gas flow in the desired direction.
  • the flow pattern can be influenced, and it can be determined whether the flue gas is to leave the primary chamber 2 at the leading edge, the trailing edge, or both.
  • baffles 11 are arranged on the separating plate 10, to ensure good mixing and turbulence in the secondary chamber 3.
  • the baffles are also movable to a desired position and may optionally be removed or interchanged with baffles having a different geometry.
  • a baffle 12 Also in the top wall is arranged a baffle 12.
  • An ash hopper 13 is arranged away from and below the grate 6 on the opposite side of the feeding area.
  • a flue outlet 14 In the top wall of the combustion chamber is arranged at least a flue outlet 14.
  • nozzles 16a for secondary air are arranged in the wall 4 of the combustion chamber.
  • nozzles 16a for tertiary air are also arranged in the area 16b.
  • the grate furnace 1 operates by dehydration, degassing and pyrolysis being carried out in the primary chamber 2.
  • combustion of gases is performed.
  • the temperature in the primary chamber 2 is preferably in the range 500-700 °C, while the secondary chamber has a temperature of approximately 1000 °C.
  • the temperature in the primary chamber 2 is set to impede gasification of heavy metal, and the formation of cinders.
  • the temperature in the secondary chamber 3 is set to ensure a good combustion of organic and chlororganic compounds.
  • Low air velocity in the primary chamber is meant to restrict the transporting of dust particles.
  • regulation of the temperature is determined by restricting the air supply to the primary chamber. This is performed by a plurality of the zones in the primary air chamber 5 being individually controlable, i.a. to avoid cooling in areas where the temperature is under control. By regulating the temperature control through air supply in the primary chamber, it is possible to stay below the critical temperatures at which cinder form.
  • Output of flue gas at the flue gas outlets 14 should be varied dependent upon what flow pattern is desirable in the secondary chamber.
  • a flue outlet is preferably situated both in the leading and the trailing edge of the secondary chamber 3.
  • Secondary air nozzles 16a, 16b are dimensioned for the actual amount of air and the flow pattern desirable in the secondary chamber 3.
  • the secondary air nozzles 16a, 16b are formed such that each can vary output velocity and output angle of the air.
  • the location of the secondary air nozzles as shown is meant as an example.
  • the nozzles 16a in the walls of the secondary air chamber are dimensioned on the basis of the volume of the secondary chamber in order to achieve velocity and a direction leading to good mixing.
  • the air pre-heating in the wall between the combustion chamber 2, 3 and the fuel container 18 also provide insulation to the fuel container and prevent high temperatures in the fuel container.
  • the heat output should, however, not be so great that the temperatures in the primary and secondary chamber 2, 3 are influenced to a negative degree.
  • Fig. 2 there is shown a more detailed example of an embodiment of present invention. Broadly the construction and operational mode is similar to what is described above with reference to Fig. 1.
  • the combustion chamber is divided into a primary chamber 2 and a secondary chamber 3 which is surrounded by an insulated steel mantel 4.
  • the two chambers 2, 3 are separated by horizontal separating plate 10, which at its ends merges into vertical baffles 11. Turbulence in the secondary chamber is secured by vertical baffle 12.
  • Below the grate 6 is arranged five primary air boxes 5 for distribution of primary air. These are furnished with supply pipes 21 for recirculated flue gas, and supply pipes 22 for primary air which is heated by a heat element 25.
  • the guillotine 8 adjusts the height of the fuel being supplied to the grate 6.
  • the fuel emerges from the cell feeder 9, which simultanously shuts off air to the fuel container 18 and provides for closing off the fuel feed.
  • pre-combustion and glowing by means of adjusted air supply and resistance is performed in the ash combustion chamber 19.
  • the grate 6 is cooled by the supply of cooling medium through the supply pipes 20.
  • a cooling element 23 is arranged on the flue gas duct 14, so as to cool the flue gas before moving through the pipe 24.
  • Fig. 2 there is shown an observation glass through which the combustion process can be observed.
