  • Figure 2 is a schematic side view of a second arrangement and method according to the invention.
  • Figure 4 is a schematic view of a combustion plant arrangement comprising an arrangement of the invention.
  • the gasification equipment 3 may be any gasification equipment known per se, such as a circulating fluidized bed gasifier, i.e. a CFB gasifier.
  • a circulating fluidized bed gasifier i.e. a CFB gasifier.
  • the gasification of the fuel F takes place in a reactor 7 of the gasification equipment.
  • the alkali metals contained in the fuel remain in a solid state.
  • Alkali metals in solid state flow with the fuel gas P into the separator 4, where they are removed from the product gas G.
  • the alkali metals content of the product gas to be conveyed into the combustion plant is very low, even to the extent that the product gas G is in practice preferably free of alkali.
  • the low alkali metals content of the product gas G essentially reduces, or, in practice, even abolishes altogether the corrosion risk of the combustion plant. This allows e.g. corrosion of superheaters possibly provided in the combustion plant to be reduced.
  • a particularly high amount of alkali metals is found in agro fuels.
  • a further advantage of the low temperature to be mentioned is that it is below the typical sintering temperature of alkali metals, so alkali metals are unlikely to sinter on the surfaces of the reactor 7. This allows the cleaning interval of the reactor 7 to be extended.
  • the operation of the CFB gasifier is based on recycling of the bed material. This kind of situation is achieved by increasing the flow rate of the fluidization gas to be higher than the terminal rate of the particles. As a result, the bed becomes turbulent and the particles are carried in the fluidization gas to the top part of the gasifier 7 and from there into the cyclone 6 of the gasifier.
  • the separator 4 may comprise a cyclone, or one of the other separators mentioned above, which separates solids S from the fuel gas.
  • the product gas G produced as a result of the separation is conveyed into the combustion plant.
  • the bottom ash on the bottom of the reactor 7 may contain coal. It may be removed by means of a bottom ash oxidizer 11 , such as a wind sieve known per se. The oxidizer blows air and, with it, the light coal upward for gasification in the reactor 7.
  • the combustion plant 5 may be a boiler, known per se, in which the product gas G may be burned and the generated thermal energy is recovered into water and/or steam by means of different thermal surfaces, such as the boiler walls, superheaters, boiling surfaces and economizers.
  • the combustion plant 5 may be a furnace, such as cement kiln, in which the energy obtained by burning the product gas is used for carrying out a chemical or physical process.
  • the combustion plant arrangement may comprise fuel pre- processing means 2, which may include drying means for reducing the moisture content of the wet fuel.
  • the drying means may comprise a belt drier, for example.
  • the arrangement of the invention is characterized in that: the gasification equipment comprises means for gasifying fuel to produce a product gas at a low temperature and in that the arrangement further comprises a separator arranged between the gasification equipment and the combustion plant so that substantially all the product gas flows through it from the gasification equipment into the combustion plant, the separator comprising means for purifying the product gas of solids.
  • the method of the invention is characterized by adjusting the temperature of the gasification equipment so that it is at most 800°C, conveying the fuel gas generated in the gasification from the gasification equipment into the separator, purifying the fuel of solids, whereby product gas is produced, and conveying the product gas into the combustion plant for combustion.

Abstract

La présente invention concerne un système et un procédé de combustion de combustible. Le système (1) comprend un équipement (3) de gazéification destiné à convertir le combustible (F) en produit gazeux (G) par gazéification et une unité (5) de combustion destinée à brûler le produit gazeux (G). L'équipement (3) de gazéification comprend un moyen pour gazéifier le combustible à faible température. Le système (1) comprend également un séparateur (4) disposé entre l'équipement (3) de gazéification et l'unité (5) de combustion de sorte que pratiquement tout le produit gazeux (G), transporté à l'intérieur de l'unité de combustion, circule à partir de l'équipement (3) de gazéification à travers le séparateur et à l'intérieur de l'unité (5) de combustion. Le séparateur (4) comprend un moyen pour purifier le produit gazeux (G) de solides.
