A fixed bed gasifier has a clinker breakup device. The tapping element of the clinker breakup device can be positioned at different points, allowing the tapping element to be small but capable of reaching all regions of the fuel particle bed. The tapping element intermittently enters the fuel particle bed in gasifying operation. Before it re-enters the bed, the drive mechanism adjusts the position of the tapping element so that it does not enter the same tapping channel again. Repeated local spiking at different times and locations moves the gasifier bed and disrupts the sintering of clinker particles that can block the gasifier cross section. Gas continues to flow through individual zones over the entire cross section, and not just in the tapped channel. Lumps of clinker that have sintered together are conveyed onward—toward the support device—or else broken up.

The invention relates to a method for the disposal of a composite material, in particular a composite material contaminated, for example, by radioactivity and containing fluorine impurities. The inventive method for the disposal of a component containing a composite material with a composite matrix and a technical fiber, is characterized in that the component is chemically gasified, wherein the composite material is technically completely decomposed into its basic components, wherein in a first step the composite matrix is dissolved and in a subsequent step the remaining starting materials and intermediate products are thermally decomposed and reacted with added process gases, wherein at least in the subsequent step a reactive gas is supplied and the subsequent step is conducted endothermically.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

The present invention includes a gasifier for gasifying fuels having a container with a top, sidewalls and a bottom for facilitating the gasifying process. One or more open vertical shafts extend downward inside the container for allowing a downdraft or updraft of air and fuel for the gasifying process. A rotating bed is preferably included inside the container and below the one or more shafts for receiving the fuel. The bed rotates essentially perpendicular to the shaft to facilitate even heating and gasifying of the fuel. The bed is further movable relative to the vertical shaft in order to increase or decrease the volume of fuel flow to the fuel.

A method of producing oil, gas, and ash fertilizer from a feedstock includes inputting the feedstock into a reaction chamber having a wall, and combusting the feedstock in the reaction chamber. An electrical current flow is induced between the reaction chamber wall and the feedstock so as to cause arcing in the feedstock within the reaction chamber. Ash reaction byproducts migrate downward through the reaction chamber onto ash support structure, which is substantially electrically isolated from the reaction chamber wall. Gas and liquid reaction byproducts migrate upward through the reaction chamber to an upper chamber by a partial vacuum in the upper chamber, and are evacuated therefrom. The oil and gas are then separated from the evacuated gas/liquid products, providing the oil and the gas products. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.
