  • a char combustion chamber 52 which for the third phase oxidizes the residual solid char coming from the pyrolyzer with air bled from the compressor portion 19 of the gas turbine assembly D.
  • the bleed air that is directed into the char combustion chamber 52 from the gas turbine compressor is compressed in a super charger 54 (approximately 5% of the gas turbine flow rate) to account for pressure losses in both the char combustor chamber 52 and the pyrolyzing chamber 51.
  • the pyrolyzer 51 includes a fluid bed reactor of inert particles 55 such as sand supported on a downwardly directed conical, porous injector plate 56 apertured at the conical apex.
  • This bed of particles 32 is initially heated by an external source (not shown) to an elevated temperature for vaporization of waste material and operation is maintained with the compressed hot gases from the char combustion chamber 52. Abrasion by the fluid bed will rapidly remove char as it is formed on the surface of waste material and this fine char material thus abraded will be carried out of the fluid bed by gases and subsequently separated by particle collectors 36.
  • the primary constituent of the organic fraction ofthe solid Waste material is cellulose, the chief component of all wood and plant fibers. and hence of all paper products.
  • cellulose the chief component of all wood and plant fibers. and hence of all paper products.
  • degradation ofthe cellulose material will occur and eventually all the oxygen and hydrogen. and a substantial part of the carbon, will be driven off leaving a carbonaceous char and non-decombustible ingredients such as metal and glass.
  • Most of the carbon driven off is in the form of fine particles produced by the abrading action of the particle bed. Oxidation of this fixed carbon particulate in the pyrolyzer 51 could not be accomplished without burning some ofthe fuel gases. Therefore.
  • this char particulate is removed from the pyrolyzer and returned via a conduit 58 to the char combustor Sl where it is burned at near stoichiometric fuel air ratios for generation of the inert gases for the pyrolyzer 51.
  • One construction for the char combustor 52 in accordance with the present invention and as illustrated in FIG. 2 is a vortex combustor consisting of a cylindrical housing 57 with a ceramic lining and into which compressor air with entrained fine char particles recovered from the pyrolyzer gases by the particle collectors 36 via conduit 58 is introduced tangentially via a conduit 59 at high velocity such as 300 feet per second causing gases in the combustor chamber 52 to flow in free vortex motion.
  • Centrifugal force causes solid particles entrained in the vortex to continue to rotate until consumed or slowed by contact with the walls while the inert gases increase in angular velocity and are removed from the core of the vortex and pass through a re-entrant throat section 61 and the ceramic injector plate 56 into the fluid bed pyrolyzer 51. Since the temperature in the combustor is above 3000F.. the ash and metals are melted and these molten droplets collect on the wall of the chamber. Larger particles stick to the molten ash and are exposed to a relatively high velocity air stream promoting rapid combustion. The liquid ash and metal subsequently drain through a hole 62 in the bottom of the char combustor 52 into a quench tank 63. There the molten residue is suddenly quenched in water resulting in the formation of granular residue which is removed as a water slurry.
  • the hot inert gases from the combustor 52 fluidize the particle bed 55 and volatilize combustibles therein.
  • Large pieces of solid waste that are not buoyed up by the fluid bed 55 migrate to the apex of the conical injector 56. There. these pieces are continuously exposed to the entering 3000F. gas stream from the combustor 52 and rapidly are either pyrolyzed or melted. lf melted. the molten residue drips directly into the quench tank 63 through the core of the vortex combustor chamber 57.
  • the hot gases leaving the fluid bed 32 entrain many ash particles which must be removed such as by the particle collectors 36 before the gases are allowed to enter the turbine. Large particulate matter. if allowed to pass through the turbine. will damage the turbine severely. Gas cleaning by the particle collectors 36 and accomplished for the turbine also satisfies the clean air requirements for exhaust gases.
  • the particle collectors can take a number of different forms such as inertial separators. electrostatic precipitators and mat filters.
  • the particle collectors 36 schematically illustrated can be a combination of inertial separators followed by electrostatic precipitators. The inertial separators remove all but the smallest particles. and these small particles are removed by the electrostatic precipitators.
  • inertial separators use centrifugal force to separate particles from the gas stream and can provide efficiencies of 97.8% and greater for particles as small as l0 microns in diameter. but the efficiency degrades for particles smaller than this size.
  • the fine particles which tend to follow the air flow out of inertial separators are least likely to injure the turbine.
  • inertial separators are particularly suited for use in the first stage of a two stage separator because they efficiently remove large particles, leaving only the fines for the second stage.
  • Electrostatic precipitators directly charge the particles in the gas and subsequently attract them to a surface charged with opposite polarity. Since the forces of separation are applied directly to the particles without disturbing the gas flow, all sizes of particles are collected efficiently; however. the high collection efficiency for the fine particles (5 microns and below) is particularly good. As temperature is increased in an electrostatic precipitator, the electrical characteristics of the hot gas change due to molecular action, and it becomes more difficult to charge the dust particles. Fortunately. increased pressure as utilized in the air chamber of the present invention tends to off-set this characteristic. Mat filters have excellent collection efficiency for both coarse and fine particles and filter material is available made of fine fibers (5 to 7 microns in diameter) of silicon dioxide and aluminum oxide which can be used as filler material up to 2300F.
  • the high temperature of the fuel gas going from the pyrolyzer 51 to the gas turbine combustors 53 will assist.
  • the gasifier combustion method and apparatus of F IGS. 1 and 2 operates exceptionally well to avoid air pollution.
  • S and HCl are removed in the fluid bed pyrolyzer 51 by reaction with basic ash materials such as CaO and MgO.
  • Limestone or dolomite can be added to the pyrolyzer bed to aid this reaction. however, in most cases sufficient CaO and MgO already exist in the solid waste ash.
  • nitrogen-oxygen compounds will not be generated in the pyrolyzer chamber 51 since practically no oxygen is present.
  • Existing gas turbines such as the General Electric G 191 heavy duty industrial gas turbine or the Pratt and Whitney ST4A-8 gas turbine can be utilized.
  • FIGS. 1 and 2 Other combustion apparatus besides that illustrated in FIGS. 1 and 2 can be utilized with the present invention.
  • a simple gravity feed gasifier schematically illustrated in FIG. 5 can be utilized. in this construction. solid wastes are introduced at the top of a volatilizing chamber and fed by gravity as they are volatilized and burned to ash, which is removed continuously from the bottom. Air is directed up through the gasifier 70 after being introduced into the ash region and the air velocities are low to preclude agitation of the pyrolyzing products. After passing through the ash, the air reaches the carbon com bustion zone where the carbon is combined with a limited supply of oxygen to form carbon monoxide.
  • Water is also introduced and the resultant steam and hot carbon result in the producer gas reaction which yields hydrogen and carbon monoxide and absorbs heat.
  • the flow rates of water and air are controlled such that all the carbon is consumed. while assuring that slagging temperatures are not reached.
  • the hot gases rising from the carbon combustion zone furnish heat to pyrolyze or volatilize the incoming solid waste. thereby generating the fuel gas which is ducted into the gas turbine combustors for final combustion with the primary air flow coming from the turbine compressor.
  • Another combustion method and apparatus is schematically carbon is separated from the initial pyrolysis process.
  • Solid wastes are introduced into the upper or volatilizing fluid bed where they are pyrolyzed by hot inert gases coming from the carbon combustion fluid bed. Rapid, uniform pyrolysis is assured by the highly stirred conditions existing in the fluid bed.
  • the fuel gas resulting from the pyrolysis passes through particle collectors on its way to the gas turbine combustor.
  • the particles collected contain both ash and carbonaceous char generated by the pyrolysis process.
  • This char is burned by introducing the particles into the second or carbon combustion fluid bed and fine ash is separated from the second bed affluent by a second set of particle collectors. Ash slagging temperatures are prevented in the carbon bed by limiting the available oxygen and by introducing water or steam.
