Abstract:
[Problem] To provide a rotating classifier which can keep classification performance high and which can prevent blockages caused by biomass and the like.[Means for Resolution] The rotating classifier is characterized in that: comb teeth-like protrusion portions protruding toward a fixed member side are provided on top of rotary classification fins at intervals along the circumferential direction of the rotating classifier fins; a first gap is provided between an upper end portion of each of the comb teeth-like protrusion portions and a lower surface of the fixed member; a second gap formed between a protrusion portion and a protrusion portion adjacent to the protrusion portion is connected to the first gap; and an air stream flowing from the radial outside to the radial inside of the comb teeth-like protrusion portions through the first gap and the second gap is formed due to the rotation of the rotary classification fins.

Abstract:
A method and an apparatus for treating and utilizing waste materials and mixtures thereof in multiple steps resulting in a high-yield utilization particularly of organic components of the waste for generating kinetically useful energy. The waste materials are sorted by classes, principally between organic and non-organic, e.g. metallic and ceramic, substances. The organic substances are briquetted and gasified, the produced gas being utilized for the direct and indirect generation of electricity and heat.

Abstract:
The present invention describes a process for the disposal of residual substances from waste incineration plants as well as activated coke and/or activated carbon. For this purpose the residual substance as well as activated coke and/or activated carbon is introduced into the annular shaft (3) of the primary chamber (2) of the furnace (1). In the primary chamber (2) a temperature of 1250.degree. C. to 1500.degree. C. is set. The molten material flowing off leaves the primary chamber (2) together with the flue gases through the central outlet (4). The molten material is passed through the secondary chamber (5) and is discharged as slag. The present invention furthermore describes an apparatus for such process, where in the furnace roof (10) of the primary chamber (2) of the furnace (1) one or several burners (7) are disposed and at one or several points (22) of the furnace roof (10) secondary air is introduced into the primary chamber (2) and at one or several points (23) of the furnace roof (10) tertiary air is introduced into the primary chamber (2).
Abstract:
A pulsed atmospheric fluidized bed reactor system is disclosed and claimed along with a process for utilization of same for the combustion of, e.g. high sulfur content coal. The system affords a economical, ecologically acceptable alternative to oil and gas fired combustors. The apparatus may also be employed for endothermic reaction, combustion of waste products, e.g. organic and medical waste, drying, calcining and the like.
Abstract:
The preferred embodiment of the invention disclosed herein includes apparatus for and the steps of separating glass, metal and other generally non-combustible material from refuse to provide a volume of generally combustible refuse, shreddingthe volume of combustible refuse into relatively small particles and mixing the particles with primary combustion air, which is used to convey the particles to a combustion chamber. Auxiliary burners are used to heat the combustion chamber to a predetermined temperature above which the particles are self-igniting and use of the burners is thereafter discontinued unless the temperature falls below the predetermined temperature. The particles are separated as they are injected into the combustion chamber with a cyclonic motion. In the combustion chamber the mixture is ignited and converted to combustion gases which flow through the chamber. The flow of secondary air is regulated to provide maximum combustion temperature for the particles and negative pressure is maintained in the chamber to control the flow rate of the gases and to assure that the gases are generally completely combusted. The combusted gases are exhausted to an associated device such as a steam boiler or other device using the heat energy and thereafter are exhausted to the atmosphere.
Abstract:
A method for processing material that contains biomass. The material is led onto a conveyor. The conveyor conveys the material to an apparatus for mechanical processing and/or to a further processing plant. The moisture content is measured and/or the size of pieces of non-combustible material and/or the content of non-combustible material in the material flow is measured in connection with the conveyor. Based on at least one of the measurements, material is conveyed to the material to be conveyed for further processing and/or to the apparatus for mechanical processing, or to at least one material to be conveyed elsewhere than to the further processing plant or the apparatus for mechanical processing. Also a system for processing material that contains biomass.
Abstract:
Improved combustion of biomass is achieved by injected first and second streams of biomass from a burner where the first stream of biomass has a median particle size larger than the biomass of the second stream and oxygen is injected with the first stream to provide an oxygen-enriched environment around the larger median sized particles. The oxygen-enriched environment is achieved either by injecting the oxygen directly into the first stream or by premixing the oxygen with the conveying air of the first stream.
