摘要:
A method according to the present invention for reducing the creation of dioxins during the burning of a biomass containing a contaminant, wherein the contaminant is solvated or neutralized in the presence of a corresponding solvent, includes the steps of prior to the burning or reacting (herein collectively referred to as burning) of the biomass, conveying the biomass and the solvent into a biomass washing means, washing the biomass in the solvent in the washing means, and once at least a portion of the contaminant has been washed from the biomass, conveying the biomass from the washing means and into a biomass burner, and conveying the solvent from the washing means.
摘要:
A storage bin arrangement especially suited for receiving, storing and discharging, in accordance with a combination of induced vertical flow and impelled retrieving concepts, bulk solid materials, in one embodiment of which essentially the entire bin itself is arranged for responding to a circular conveying type vibratory helical stroke movement generated by a pair of electric motors secured to the opposite sides of the bin in oppositely oriented positions to dispose their respective driving shafts at opposite, typically 45 degree angulations with respect to the horizontal, and with each such motor shaft driving a pair of eccentrically oriented weights, with the bin having a low profile bottom section equipped with one or more off center located, vertically oriented, vertically rectilinear, discharge chute arrangements and having one or more internally applied baffles, either of inverted cone type or one or more rows or levels of internally applied centerless, radial, sidewall mounted type, in spaced relation, above the bin low profile bottom section, and in a second embodiment, a bin actuator having the features indicated above that is mounted below a large discharge opening in a conventional stationary bin, while responding to the same type of helical vibration to effect both types of material discharge from the bin free of excess beadroom; either embodiment can also eliminate vertical space consuming pant leg type discharge chutes, and provide for optional divided flow of the bulk solid materials therefrom.

摘要:
A feed system for feeding solid propellant or explosive energetic materials, e.g. in the form of chunks, into a molten salt furnace for destruction of said materials by oxidation with air, while substantially avoiding the danger of detonation of such materials during feeding. The system comprises a feed hopper separated from the molten salt furnace by a barrier such as a concrete wall. The feed hopper is preferably vibrated to move the chunks of waste to an inclined chute which passes through a penetration in the barrier to the furnace, the chute also being preferably vibrated to facilitate passage of the waste material. The chunks of waste are discharged from the inclined chute either directly into the molten salt bath in the furance, or added incrementally thereto by a lock valve arrangement.

摘要:
A system for handling refuse derived fuel (RDF) devised to make RDF fired power plants practical, that includes a method and apparatus for receiving, storing and discharging, distributing and feeding RDF at the plant that accepts such material for fuel, which has been shredded to a predetermined nominal size and usually has most of the ferrous metals removed therefrom, which system includes a relatively large activated bin for primary surge capacity purposes that initially receives and stores the RDF, to provide a binned quantity of same from which as continuous flow of the RDF can be generated that will result in a pulsation free, steady supply of RDF to the plant furnace or furnaces, for firing the power plant involved, with one or more trains located adjacent the locale of the plant furnace to be fired, each of which includes several metering activated bins that are actuated to supply an underlying vibrating feeder that conveys the RDF to the furnace fuel chute, with the activated metering bins of each train being supplied from by one, or parallel, vibrating conveyors. For some trains, two metering bins can be provided for redundancy, that is, for the purpose of using either of such bins to supply the RDF to the vibrating feeder underlying same in the event that one of such activated bin arrangement does not operate.
