Definitions

  • the present invention relates to a plant and method for incineration of industrial and household waste and sludge, comprising a generally vertically directed waste infeed chute, a waste infeed means at the bottom of the chute for advancing the waste in a generally horizontal direction, possibly an infeed sluice and a downstream located combustion chamber, comprising a movable grate system at the bottom, for advancing, drying, igniting, burning, and outburning the waste in the combustion chamber before the slag is conveyed out of the combustion chamber down into the slag chute.
  • the waste infeed chute is generally directed vertically in order that the waste can slide downwards through the chute by gravity, while the waste infeed means in the bottom of the chute removes, advances and feeds the waste lying at the bottom into the combustion chamber, possibly through an infeed sluice.
  • Known waste infeed means at the bottom of the waste infeed chute are e.g. one or more hydraulic pistons, apron feeders, moving grates or actual combustion grates, known e.g. from US patent No. 4,494,469 and DK patent No. 170,493.
  • Characteristic for the known waste infeed means is e.g. that complete filled waste bags and waste of similar bulk size easily and undivided can be fed into the combustion chamber, potentially via an infeed sluice, after having passed down through the waste infeed chute, in which the waste functions as a relatively dense plug, securing only small amounts of combustion air following the waste into the combustion chamber, avoiding propagation of the combustion back into the waste infeed chute.
  • the combustion takes place in the oven chamber at a pressure lower than ambient pressure, e.g. secured by placing an induced draft fan for the flue gas immediately in front of the chimney of the incineration plant.
  • Sludge from waste water cleaning facilities has previously to a great extent been disposed of by spreading on fields as a fertilizer, but stricter environmental rules lead to a demand that sludge of this kind, like many other liquid waste materials, is disposed of by other means, e.g. by combustion.
  • Special sludge ovens for combustion of waste water sludge are known, but will normally require supply of supplementary fuel, e.g. in the form of oil or gas.
  • the sludge When feeding the sludge through the ceiling as well as through the wall of the oven, directly into the waste combustion chamber, the sludge falls through a flue gas stream at a temperature of approximately 1000°C, drying out and carrying away many of the fine-grained sludge particles, so that the content of dust in the flue gas is raised remarkably, which is unconvenient, the boiler after the combustion oven being further smudged and the flue gas cleaning demand being increased.
  • an incineration plant as mentioned in the introduction, by providing the waste infeed chute or sluice with at least one infeed tube for adding sludge to the waste in the chute or sluice, and at least one pressure-feed applicance for feeding the sludge through the at least one infeed tube into the waste.
  • the sludge is fed into the waste infeed chute or infeed sluice, at a position in which there exists a pressure lower than ambient pressure, when the plant is working so that unhygienic dust is sucked into the cold waste and the odour materials are sucked into the combustion chamber, whereby they are burned and removed.
  • the sludge is fed into the combustion chamber in such a way that the development of dust during the combustion process is minimized and the infeed of waste is still performed optimally with respect to combustion, as normally, without any cumbersome, expensive and unhygienic comminution of the waste.
  • the infeed is performed close to the bottom part of the waste infeed chute or in the infeed sluice, so that generally all of the time waste is present in the infeed chute or infeed sluice at the level of the mouth of the infeed tube.
  • the sludge By providing the infeed tube for sludge in the wall of the waste infeed chute facing the combustion chamber or in the ceiling of the infeed sluice, the sludge will always be positioned on top of the waste being fed into the waste combustion chamber and thus being dried out immediately when entering the combustion chamber.
  • the infeed tube or tubes are preferably connected to a pipeline for the supply of sludge from a pressure-feed applicance upstream connected to a silo for temporary storage of sludge.
  • the infeed of sludge can be performed almost hermetically closed with respect to the surroundings.
  • the pipeline for supply of sludge may be provided with one or more ring nozzles, for lubricating the inner wall of the pipeline with e.g. a polymer for reduction of the sliding friction between sludge and pipeline.
  • the sludge to be incinerated in the plant in accordance with the invention may be selected from the group consisting of sludge from waste water cleaning, crude oil sludge, petrochemical waste products, animal sludge, liquid waste, slurry and liquid manure or mixtures thereof, possibly with admixture of materials selected from the group consisting of grate screanings, boiler ash, filter ash, flue gas cleaning products, other waste products from waste incineration plants, shredded waste, plastic waste, car fluff, and stabilizers reducing dust and/or vapour generation and/or unwanted chemical reactions in the combustion chamber.
  • the sludge is supplied to the incineration plant via a hermetically closed supply system.
  • the infeed quantity of the sludge can be used as one parameter for controlling the burning of waste in the combustion chamber.
  • the method preferably comprises pressure-feeding of sludge of varying composition, possibly with admixture of further material to be disposed of or material providing stabilization of the sludge mixture.
  • Fig. 1 shows an incineration plant comprising infeed tubes for adding sludge to the waste in accordance with the present invention
  • Fig. 2 shows an arrangement comprising four infeed tubes, via a manifold connected to a pipeline for supply of sludge, and
  • Fig. 3 shows a rough outline of a plant comprising a waste incineration plant and corresponding pipeline for sludge and a pressure-feed appliance provided to transport the sludge and a silo for temporary storage of sludge.
  • the incineration plant shown in Fig. 1 comprises a waste infeed chute 1 for industrial and household waste and a grate system 2 for advancing the waste through the inlet to the combustion chamber and for advancing the waste in the combustion chamber 3, positioned downstream of the chute 1.
  • the waste infeed chute 1 comprises an infeed tube 4 for supply of sludge.
  • the infeed tube is placed close to the bottom part of the waste infeed chute 1 and in the wall in the waste infeed chute 1 facing the combustion chamber 3.
  • the infeed tube 4 for supply of sludge is, as shown in the drawing, positioned to debouch in a downwardly slanted angle into the waste infeed chute 1.
  • Fig. 2 shows how four infeed tubes 4 are connected to a pipeline 5 for supply of sludge via a manifold 6, intended to provide a uniform distribution of the added sludge across the four infeed tubes 4, the sludge being equally distributed across the feeding direction for the grate system 2 in the waste combustion chamber 3.
  • Fig. 3 shows how sludge can be supplied from a storage silo 7 for temporary storage of the sludge, forward to the infeed tube 4 in a hermetically closed system.
  • a pressure-feed appliance 8 is provided close to the silo 7, and a pipeline 5 is connected between the pressure-feed appliance 8 and the infeed tube 4, the pipeline 5 potentially comprising a ring nozzle 9, for lubricating the inner wall of the pipeline 5 with e.g. a polymer for reduction of the sliding friction between sludge and pipeline 5.
