Materials recycling apparatus

Abstract

Materials recycling processes that include a combustion stage can operate very efficiently, but can produce exhaust gases that are high in carbon monoxide and the like. We describe a treatment unit which comprises a chamber for receiving the material, a heat source for (preferably) heat-treating the material and for initiating combustion, and a gas outlet from the chamber, which allows the gas that is exhausted via the outlet to be supplied to the air inlet of an associated boiler unit, with the air inlet and a separate fuel inlet feeding a burner for combusting fuel from the fuel inlet in air from the air inlet in order to heat a transfer fluid. In this way, the unburnt elements of the gas expelled from the chamber are included in the combustion process of the boiler unit and fully combusted. A corresponding method is also disclosed.
