Abstract:
A solid waste disposal system is described with a storage and receiving carousel, a shredder, a dryer, a compressor-turbine assembly for compressing air for combustion of waste and for receiving hot gasses produced in the combustion process. Two combustion systems, a fluid bed reactor and a gasifying pyrolyzer, are described. Particulate matter harmful to the turbine and also causing air pollution is removed from the hot high pressure gas upstream of the turbine. The malodorous air from the waste storage, shredding and drying is compressed and used for combustion and the part of the hot exhaust gases from the turbine are used in the dryer.
Abstract:
The invention provides an apparatus which consists of two fluidized beds 1 and 2 separated by a vertical divides' 5. A positive displacement device such as an auger 3 moves the bed material from the reduction side to the combustion side of the device below the fluidization zone. The height of the two fluidized beds is equalized by movement of the bed material through a hole 4 In the vertical divider, from the high temperature side 1 (zone 1) to the tow temperature side 2 (zone 2). The bed material that moves through the hole 4 provides energy to drive reactions that may occur on the reduction side. Energy may also be provided to zone 2 by means of conductive and radiative heat transfer through the dividing wall 5. Energy is provided to zone 1 by means of an exothermic reaction, typically combustion of a fuel 13 using air 12.

The invention provides an apparatus which consists of two fluidised beds 1 and 2 separated by a vertical divides'5. A positive displacement device such as an auger 3 moves the bed material from the reduction side to the combustion side of the device below the fluidisation zone. The height of the two fluidised beds is equalised by movement of the bed material through a hole 4 In the vertical divider, from the high temperature side 1 (zone 1) to the tow temperature side 2 (zone 2). The bed material that moves through the hole 4 provides energy to drive reactions that may occur on the reduction side.

Leak-proof process chamber (1) of reactor contains area for feeding of wet small particles of solid fuel waste, their pyrolysis and carbonization (14), connected to areas for feeding (4) and heating (5) of oxygen-containing agent. Channel for feeding of oxygen-containing agent (15) is connected to metering hopper of wet small particles of solid fuel wastes (16), which are used for formation of fluidized flow. Additional volume of oxygen-containing agent is injected into reactor as a part of main flow that is necessary for further combustion of small particles of solid fuel waste that passed through pyrolysis area (8) and carbonization area (7) and conversion of their moisture into superheating steam. Inventions allow complete utilization, of small fractions of derivative products, ensure generation of gas with high calorific capacity and increase output and quality of finished products and discharge is performed cyclically with maintenance of sealing of reactor processing space. 2 and 4 of depending claims, 1 dy; 2 table 1 ref.

The basket according to the invention can be used to incinerate waste inside an incinerator for a duration longer than fifteen minutes with no need for waste to be molten earlier, particularly when waste is introduced inside the incinerator. The basket is composed mainly of a glass fibre envelope (10): it is preferably stiffened by a lightweight metal structure (12) located inside or outside the envelope or built into it. A gripping handle (14) is installed on top of the assembly that is stiffened at the top by a metal tube (16) to which a lightweight metal structure (12) is fixed and by a base formed from a drip pan (18) fixed to the base of the lightweight metal structure (12). Application for incineration of toxic waste.
