    Abstract: Processes and systems are provided that include introducing ammonia liberated from organic waste to a coal burner in a coal burning power plant, preferably for NOx removal at the power plant. The ammonia is preferably either ammonia liberated upon drying a mixture of organic waste and coal combustion by-products or ammonia liberated when organic waste is mixed with coal combustion by-products and one or more alkaline additives. Also provided are processes and systems of fueling a coal burner of a power plant with coal and either a dried mixture of organic waste and coal combustion by-products, or a mixture of organic waste, coal combustion by-products and one or more alkaline additives. The present invention is further directed to mixtures of either organic waste and coal combustion by-products, or mixtures of organic waste, coal combustion by-products and alkaline additives made by the processes of the present invention.

    Abstract: The starting point is a process to improve the performance of the incineration of combustible waste material in an incineration chamber, whereby the waste material is conveyed to a burner flame where it is burned with combustion air at a temperature in the range from 1100null C. to 1700null C. null2012null F. to 3092null F.null. On this basis, in order to create a process that allows a capacity increase of installations employed for the exothermal incineration of waste materials, it is proposed according to the invention that at least part of the combustion air is replaced by an oxygen-rich gas having an oxygen content that is higher than that of air and that the oxygen-rich gas is mixed with a cooling medium.

    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.
