    Abstract: The present invention provides a method for treating the wastes of polyester-manufacturing processes. The method of the invention comprises combining the fuel with a first waste byproduct stream to form a combined fuel and first waste byproduct stream mixture that is combusted in a furnace. The present invention also provides certain useful variations of this method in which one or more of the following steps are performed: a second waste byproduct stream is introduced and treated in a regenerative thermal oxidizer, a third waste byproduct stream is introduced and treated in a waste water treatment plant, or a fourth waste byproduct stream is introduced and treated in a fluid bed incinerator. The present invention also provides an apparatus that executes the methods of the invention.

    Abstract: A municipal or like refuse, from which large articles of metals have been removed, is mixed with an alkaline substance like limestone preferably in a triple screw mixer, and then advanced along the pyrolysis path in which the refuse mixture is subjected to heat from combustion gases from an incineration chamber therebelow. A portion of the pyrolyzed product is recycled to the upstream side of that path and the remainder of the pyrolyzed product is scrubbed with an aqueous medium, e.g. water and/or aqueous acetic acid and the washed pyrolyzed product is then incinerated to produce the combustion gas.

    Abstract: In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650.degree. C. at a filtration velocity of 1-5 cm/sec under a pressure of from -5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

    Abstract: A method of treatment of waste material includes the steps of mixing the waste material with binder and pelletizing the mixture. The pellets are then coated with a non-agglomerating material selected to permit firing of the mixture without pellet agglomeration at a temperature above 1300.degree. C. The coated pellets are fed to a kiln and fired at a temperature above 1300.degree. C. before being discharged from the kiln. At least some of the heat of firing the pellets is recovered and recycled to the kiln.
