    Abstract: A fluidized bed reactor and system and method utilizing same for the combustion of waste fuels in which the reactor vessel is divided into three vessels. Waste fuel is introduced into the fluidized bed within one vessel where it is mixed with bed make-up material that is controlled to provide an ideal environment for the generation of pyrolytic gases. The fluidized bed material is pneumatically and gravitationally conveyed downwardly, and injected into a fluidized bed within the second vessel where the involatile organic material undergoes combustion in an oxidizing atmosphere. The bed material in the second vessel is pneumatically conveyed upwardly and divided into two portions, one of which is recycled back to the first vessel. The other portion of the bed material in the second vessel is circulated to a fluidized bed within the third vessel where heat is recovered. The bed material in the heat recovery vessel is gravitationally conveyed back to the second vessel to regulate the temperature in the latter vessel.

    Abstract: Described is an apparatus for separating contaminated material from impurities contained therein, by heating by means of hot gases. The apparatus has receiving chambers for accommodating the contaimated materials, and heating chambers which surround the respective receiving chambers. Each heating chamber is divided into first and second chamber means of which one is designed to carry a flow of burner gas while the second is designed to carry a flow of coolant. The first and second chamber means extend in mutually separate relationship and in a helical configuration around the associated receiving chamber. Each receiving chamber has gas distributor members to produce a turbulent flow in the chamber.

    Abstract: Method and apparatus is disclosed for thermally decomposing waste material from several batch furnaces plumbed into one afterburner. The afterburner is modified to mix and combust in a controlled manner an otherwise explosive mixture of fumes from several furnaces. The entire system is regulated only by the temperature of incinerated gases from the afterburner. The furnaces are operated in a sequenced, overlapping staged manner to produce a generally constant fume loading permitting significant cost savings in equipment and operation.

    Abstract: A plant for thermal waste disposal includes a pyrolysis reactor converting waste into carbonization gas and substantially non-volatile pyrolysis residue and a discharge device connected to the pyrolysis reactor. A combustion chamber operated with an oxygen excess is connected to a carbonization gas discharge fitting of the discharge device for receiving the carbonization gas. A residue sorting device is connected to the pyrolysis residue outlet of the discharge device for sorting out coarser coarse components substantially including non-combustible ingredients such as rocks, glass shards, broken porcelain, and metal parts, from combustible finer coarse components. A transport device connected to the residue sorting device transports the finer coarse components. A grinding apparatus has an inlet side connected to the transport device and a discharge side for feeding the finer coarse components to the combustion chamber after grinding. The combustion chamber maintains combustion gases produced from delivered combustible material for a sufficiently long time at a sufficient temperature level to produce molten slag. The combustion chamber has an outlet for removing the molten slag which is cooled into a glassified form downstream of the outlet of the combustion chamber. A flue gas line leads from the combustion chamber to a chimney.

    Abstract: In order to be able to handle multiple fuels in a bubbling-bed fluidized bed combustor, a number of elements are combined together and a number of systems are described which utilize these elements in order to be able to appropriately process different types of fuels. With respect to the handling of multiple fuels by a bubbling-bed fluidized bed combustor which need not be reconfigured for each type of fuel, the combustor in the subject invention is provided with a closely-coupled pyrolyzer or gasifier. The close-coupled pyrolyzer not only permits the processing of virtually any type of fuel into two fuel streams which are immediately usable by the combustor but also has certain advantages in terms of reducing environmental pollutants. The above-mentioned close-coupled pyrolyzer also results in improved performance aside from the pollution aspects mentioned above. The close coupling of the pyrolyzer to the fluidized bed combustor also allows fluid bed combustion systems to be built in larger capacity than heretofore possible. In one aspect of the subject invention, the close-coupled pyrolyzer permits the production of higher temperature flue gases than would be done with a fluidized bed combustor without the pyrolyzer. The subject invention also allows the use of high-moisture fuels and avoids the efficiency loss, output loss and the increased boiler size that is normally associated with those fuels. The above advantages of the close-coupled pyrolyzer are improved by the provision of some specially designed auxiliary apparatus, such as a specialized deep-bed pyrolyzer, a specialized screw feeding system and the utilization of under-the-bed cooling tubes in a fluidized bed combustor. The above has detailed the building blocks useful in numerous types of systems, three of which will be described hereinafter; namely, a system for processing refuse-derived fuels, a system for processing hazardous fuels and combined-cycle gas.
