Definitions
- the invention relates to a method for burning or Gasification of material containing flammable components in the circulating fluidized bed, which is a vortex chamber for combustion or gasification, one with the top Area of the vortex chamber connected solid matter separator, a return of those occurring in the solids separator Solids to the swirl chamber and a cooling device for indirect cooling of solids by Solid matter separators come, wherein the Cooling device contains several fluidized beds by the Solids are migrated one after the other.
- a method of this type is known from WO 97/46829 A1.
- the cooling device is an uncooled fluidized bed upstream, its exhaust gases directly into the combustion be performed. Through this measure the Chloride concentration in the solids to be cooled be reduced.
- the chlorides are for aggressive Corrosion attacks on the cooling devices responsible.
- the known blowing through the fluidized bed is mainly in unfavorable cases, the chloride concentration is not suitable in the solids to be cooled sufficiently to reduce to ensure the desired protection against corrosion.
- corrosive B KCl caking Cooling tubes.
- the reactivity of the silicates, aluminum silicates or the activated silicates is essentially based on the hydroxyl groups on the silicon.
- These additives bind the alkalis and metals in the hot solids, so that chlorine is released as HCl, which is less corrosive than z.
- These solid additives are usually added to the fluidized bed in powder form, the mean grain sizes d 50 being approximately in the range from 50 to 500 ⁇ m. It is also possible for the solid additives to be introduced early into the hot solid feed line.
- Gaseous SO 2 is particularly suitable for reacting with vaporous alkali chloride or metal chloride and thereby forming sulfates and HCl in the presence of molecular oxygen.
- the released HCl is driven out of the dechlorination chamber with the fluidizing gas.
- Sulphates are not or hardly corrosive and can with the ash removed from the process z. B. be deposited.
- SO 2 can be added to the gas space in a molar concentration of 0.25 to about 6 times the concentration of the released HCl.
- the SO 2 can also be introduced by sulfur-containing materials, which release at the high temperatures in the dechlorination chamber SO 2 or release in an oxidizing atmosphere SO 2.
- the fluidized bed in the dechlorination chamber can be with or without indirect cooling work; usually you become this Keep the fluidized bed free of indirect cooling.
- the other fluidized beds contained in the cooling device by flowed through liquid, gaseous or vaporous coolants Heat exchanger. By eliminating or at least May reduce the corrosiveness of hot solids you keep the temperature high in the hottest fluidized bed what z. B. steam overheating benefits.
- the material to be burned or gasified can be of different types.
- B. are coal, lignite, biomass (e.g. wood or straw), solid and / or liquid waste or sewage sludge, several of these materials can also be mixed.
- the material to be burned or gasified is given through the line (1) into the swirl chamber (2) leading to a circulating fluidized bed. With the top area the vortex chamber (2) is therefore through the channel (3) Solid separator (4) connected, which is z. B. um a cyclone. Partially dedusted gas is drawn in line (5) and it does not become one shown, known cooling and cleaning respectively. Part of the accumulating in the separator (4) Solids is through the return line (6) via a Siphon (7) led back into the swirl chamber (2). The Flow in the siphon is through a fluidizing gas stream controlled, which is introduced in line (7a).
- the swirl chamber (2) In the lower area of the swirl chamber (2) there is a Grate (8), from which oxygen-containing fluidizing gas flows up into the chamber.
- the fluidizing gas comes from line (9) and first enters one Distribution chamber (10) before it flows through the grate (8). Ash is removed from the chamber (2) through the extractor (11) away.
- the material to be burned or gasified can are different types of granular solids combustible components, liquid or pasty substances may be added.
- the temperatures in the Swirl chamber (2) are usually in the range of 700 up to 1100 ° C and preferably 800 to 1050 ° C.
- the Eddy gas is constantly a part of the solids through the Channel (3) led to the separator (4).
- the amount of Solids, which one through the return line (6) in the Cyclic chamber (2) returns, is usually hourly at least 5 times the amount of solids that is in the swirl chamber (2) on average.
- the temperatures range from 700 to 1100 ° C and mostly have 800 to 1050 ° C, are by the Line (14) fed to a cooling device (15).
- the cooling device (15) has a Dechlorination chamber (16) and three cooling chambers (16a), (16b) and (16c).
- the cooling chambers contain heat exchangers (17) and (18) for indirect cooling of the solids there as fluidized beds (21), (22) and (23) are present.
- Weir-like chamber walls are located between the beds (21a), (22a) and (23a), fluidizing gas is through Lines (21b), (22b) and (23b) are supplied.
- Fluidizing gas can e.g. B. is air.
- the dechlorination chamber (16) has a feed line (20a) for fluidizing gas (e.g. air), the gas from which a grate (20b) flows into a fluidized bed (20) and then first in the one above the fluidized bed (20) Gas space (25) arrives.
- a gas room is also above the other fluidized beds (21), (22) and (23).
- the Gas is discharged through a manifold (26), which opens into the swirl chamber (2) and the exhaust gas of the cooled fluidized beds (21), (22) and (23) with it.
- the dechlorination chamber (16) can have its own Have gas discharge line (26a), shown in dashed lines is.
- the dechlorination chamber (16) is provided with a feed line (27) for solid additives and with a feed line (28) for gaseous additives. All or part of the gaseous additives can also be supplied through line (28a).
- Solid additives are silicates, aluminum silicates and / or activated silicates or mixtures which contain at least one of these additives.
- the gaseous additive used is gaseous SO 2 or other sulfur-containing materials which release SO 2 in an oxidizing atmosphere. It is important that the content of alkali and metal chlorides which are brought in with the hot solids through line (14) is largely reduced by the additives.
- the solids which leave the dechlorination chamber (16) via the weir-like wall (21a) and pass into the fluidized bed (21) have a maximum of 20% of the alkali metal and metal chloride content present in the solids of the line (14) is present.
- the chilled solids contained in the cooling device (15) have partially given off their heat, being used as a coolant z.
- B. boiler feed water or steam is used, through the line (30) back into the vortex chamber (2) performed. Some of the chilled solids can also removed from the process what is in the drawing is not shown.
- the chamber (16) is fed as a solid additive 23 kg / h of the activated silicate ICA 2000 (manufacturer: ICA Chemie, A-3384 Gross-Sierning) and as a gaseous additive SO 2 through lines (27) and (28) , a concentration of 30 ppm SO 2 being established in the gas space (25).
- the ash cooled to 720 ° C. is drawn off through line (30) and led back into the swirl chamber (2).
- the treatment in the dechlorination chamber (16) reduces the chlorine content in the solids to 10% of the initial content.
