    摘要: An industrial waste and household waste is treated by a pyrolysis step for carbonizing waste containing organic substance in a condition sealed from an air so as to separate to a pyrolysis gas and a pyrolysis residue; a gas cracking step for introducing the pyrolysis gas after the pyrolysis step so as to react an oxide component in the pyrolysis gas through an oxidization reaction and thermally decompose high molecular hydrocarbon in the pyrolysis gas with a heat generated by the oxidization reaction so as to obtain a cracked gas containing low molecular hydrocarbon; a residue cooling step for cooling the pyrolysis residue generated in the pyrolysis step for solidification; a mechanical processing step for crushing and sorting the pyrolysis residue solidified in the residue cooling step so as to obtain a pyrolysis char essentially consisting of pyrolysed organic substance and inorganic components; and a smelting and gasifying step for burning the pyrolysis char obtained in the mechanical processing step at a high temperature by being mixed with fuel and oxygen or air so as to melt the inorganic component of the pyrolysis char and gasify the carbon component to obtain a gasified gas containing low molecular hydrocarbon.

    摘要: A method for the repowering of an existing coal-fired facility used in the generation of electric power which makes the facility more efficient while reducing its emissions in a cost-effective manner using the following steps: a) processing the coal in use to co-produce a clean liquid fuel and a clean low Btu gas; b) replacing the pulverized coal burners of the boiler contained in the facility with burners adapted to burn low-Btu gas; c) burning clean low-Btu gas in the boiler instead of coal; d) making up the derate of the boiler by the addition of efficient combined cycle power generation; and e) crediting the revenue derived from the sale of the liquid fuel co-produced to the existing facility to render such repowering commercially viable.

    摘要: A method of generating a de-sulphurized volatile matter and a relatively low Btu gas includes the initial step of pyrolyzing coal to produce volatile matter and a char. The volatile matter is fed to a first de-sulphurizer containing a de-sulphurizing agent to remove sulphur therefrom. At the same time, the char is gasified to produce a relatively low Btu gas. The low Btu gas is fed to a second de-sulphurizer containing the de-sulphurizing agent to remove sulphur therefrom. A regenerator is provided for removing sulphur from the de-sulphurizing agent. Portions of the de-sulphurizing agent are moved among the first de-sulphurizer, the second de-sulphurizer, and the regenerator such that the regenerator regenerates the de-sulphurizing agent. Preferably, the portions of the de-sulphurizing agent are moved from the second de-sulphurizer to the first de-sulphurizer, from the first de-sulphurizer to the regenerator, and from the regenerator to the second de-sulphurizer.

    摘要: This invention relates to a two stage coal gasification plant which comprises a gasifier 1 and a predistillation retort 2. The gasifier has a plurality of gas extraction outlets 4 located in the periphery thereof which feed into a manifold 5 from where a percentage of the gas from the gasifier is extracted. Gas from the predistillation retort is extracted through an outlet near the top of the retort. An agitator 8 is provided for agitation of the coal in the agglomeration zone. The agitator is preferably automatically controlled by means of a temperature sensing device 10 located on an arm thereof.
