Method and device implemented in a reactor for the plasma treatment of carried fragmented material or of pulverized elements by a support gas where the main element is an intermediate temperature plasma (PIT) generator fed by a source of electric pulses, the amplitude of whose current is limited and for which the generating frequency, the duration of the pulses and the duration of the time spans between the pulses are determined in such a way as to generate a nonthermal plasma (PIT) of large extent, the plasma and the carrier gas flux (4) laiden with the fragments of material or of pulverized elements to be treated (5) moving along helical trajectories coaxial with the axis of the reactor at controlled angles a and β respectively relative to the plane perpendicular to the axis of the reactor, the angles a and β being able to vary in a given manner according to the properties of the material to be treated and the technological parameters and the dimensions of the reactor. Use of the invention both for the combustion of combustible powders in the boilers of electric power plants and for the generation of solid or gaseous combustible products, of given properties and dimensions, effected through the organization of plasmochemical reactions on fragments or pulverized elements of organic materials in the reactor.

A generally upright reactor system (10) for gasifying a feedstock (12). The reactor system (10) generally includes a main body (22), at least two inlet projections (24) extending outwardly from the main body (22), and at least one inlet (26) positioned on each of the inlet projections (24). Each of the inlets (26) is operable to discharge the feedstock (12) into the reaction zone (20).
摘要:
This specification relates to the field of power engineering and, more specifically, to systems for generating electricity based on the use of solid fuel, primarily brown and black coal. A coal gasification method is disclosed in which a gasifier is fed with a uniform activated coal water fuel. The droplets of fuel are ideally of equal size and have coal particles with similar granulometric composition. The fuel droplets are introduced intermittently in separate doses of fuel with a certain amount of motion being imparted thereto. The milling of coal for activated coal water fuel preparation is adjusted adaptively according to the criterion of the actual amount of volatile substances given off by the coal, and the coal is thoroughly classified according to its granulometric composition. The disclosed method can enable more extensive recovery of thermal energy from coal and more efficient electricity generation.

摘要:
The invention is directed to a process to prepare a gas mixture of hydrogen and carbon monoxide from an ash containing carbonaceous feedstock. The process involves a partial oxidation (5) obtaining liquid ash (8) and a gas mixture comprising of hydrogen, carbon monoxide and solids (10). The liquid ash is separated from the gas mixture and the temperature of the gas mixture is reduced (11) in the absence of the separated ash. The gas mixture is passed through a vertically positioned diptube (14) wherein water (15) is added to the gas mixture flowing through the diptube to obtain a gas/water mixture. The liquid is separated from the gas/water mixture. The gas thus obtained is passed together with an amount of liquid water through a venturi mixer (19) and scrubbed (24).

摘要:
The invention relates to a method and a device for producing combustible gas, synthesis gas and reducing gas from reproductive and fossil fuels, other biomass, waste or sludge. Before being conveyed to the reactor, these are separated as far as possible into gaseous and solid products, e.g., low temperature carbonisation gas and wood charcoal. They are then conveyed separately to the reactor. According to the invention, the reactor consists of a combination burner, a combustion chamber, an entrained-bed gasifier, a heat compensation channel and a water bath. The combination burner is provided with devices for burning the gaseous low-temperature carbonisation products sub-stoichiometrically, and swirl devices for spinning the liquid constituents out to the wall of the combustion chamber. The drops of liquid slag drop into a water bath. The pulverised fuel can react endothermically with the gasification medium from the combustion chamber to form gasification gas and the residual char is vortexed so that it reduces the temperature of the combustion chamber wall to below the slag melting temperature by convective heat absorption, a protective layer of solidified slag forming on the inner wall of the combustion chamber.
摘要:
A rotary fusing furnace for gasifying combustible wastes and/or coal and a method for gasifying wastes by using the rotary fusing furnace. In the rotary fusing furnace (5), a gaseous substance supplied into a combustion chamber (6) forms a rotating flow that rotates therein. The rotating flow includes an outwardly circumferential rotating flow including many particulate combustible components and an inwardly circumferential rotating flow containing many gaseous combustible components, and oxygen is supplied from an internal wall side of the combustion chamber (6) into the outwardly circumferential rotating flow including many particulate combustible components for promotion of gasification of the particulate combustible components.
