Abstract: Provided are a method of treating coal ash by mixing it with water, in which the coal ash and water undergo a temperature difference therebetween while they are mixed; and a method of desulfurization in a coal combustion boiler system, which comprises mixing coal ash that has been separated from a ash collector in the system, with water on the condition that the two undergo a temperature difference therebetween while they are mixed, and circulating the resulting mixture that serves as a desulfurizing agent into the coal combustor in the system. The desulfurization capability of the desulfurizing agent used in the desulfurization method is higher than that of the desulfurizing agent obtained through hydration of coal ash with water or steam.

Abstract: The invention concerns a plant for the thermolysis of waste products containing an organic fraction, and for simultaneous energetically upgrading these waste products comprising: a unit for loading and supplying the waste products to be treated; a thermolysis reactor for thermal dissociation under reduced pressure at high temperature. The invention is characterized in that it comprises: upstream and downstream of the reactor, a lock chamber for maintaining a partial vacuum in the reactor for ensuring thermolysis in an atmosphere with low oxygen content; first means for recuperating, in the upper part of the reactor, the organic gas fraction formed during thermolysis, and for bringing this fraction to a combustion chamber supplying a steam generator; second means for recuperating at the bottom of the reactor the solid carbon products formed during thermolysis, and for bringing these solid products to a combustion chamber supplying a steam generator or an evacuating system. The gas of the combustion chamber and the steam produced by the steam generator, in turn supply the unit producing the waste products and/or means for drying in advance of the waste products provided just upstream of the reactor.

Abstract: Dumped solid waste is mixed with sand and fed through a shredder. Sorters sort aluminum glass and ferrous materials from the shredded waste, and an indirect fired dryer heats the remaining shredded waste. Dust in gases from the dryer is removed in a bag house. Sand is added to the dried, shredded waste, and the waste is cooled and stored in surge storage. The shredded, dried, cooled and stored waste is fed to one or more reducing chamber units. Waste is moved through individual chambers within the units with augers and is gravitationally fed between the chambers. Gases from the chambers are condensed, and the condensate is stored as oils. Solid products from the reducing chamber units are cooled. The sand is separated from the solid product. The resultant solid product and oils may be sold as fuel and feedstock, or the resultant product may be pulverized and combined with the oil in a slurry which is used as a fuel or a feedstock.

Abstract: The invention is directed to a method for treating an aqueous waste material in order to reduce the volume of the material for disposal and/or landfill. In the method, an aqueous waste material containing organic compounds is contacted with calcium carbide under conditions which cause water and calcium carbide to react to produce acetylene and a residue. The acetylene is burned in the presence of the residue to further reduce the volume of material for disposal.

Abstract: A method and system for cost effectively converting a feedstock using thermal plasma, or other styles of gassifiers, into a feedwater energy transfer system. The feedstock can be any organic material, or fossil fuel. The energy transferred in the feedwater is converted into steam which is then injected into the low turbine of a combined cycle power plant. Heat is extracted from gas product issued by a gassifier and delivered to a power plant via its feedwater system. The gassifier is a plasma gassifier and the gas product is syngas. In a further embodiment, prior to performing the step of extracting heat energy, there is is provided the further step of combusting the syngas in an afterburner. An air flow, and/or EGR flow is provided to the afterburner at a rate that is varied in response to an operating characteristic of the afterburner. The air flow to the afterburner is heated.
