Abstract
A fluidized bed reactor suitable for burning polymeric waste material, particularly thermoplastics, has been developed as well as a method of using it. The reactor comprises a chamber for retaining a fluidized bed of refractory particles and burning the polymer therein. A specially adapted diffuser plate located at the bottom of the reactor controls the flow path of particles in the fluidized bed to enhance mixing and maintain uniform reactor temperatures. Means are additionally provided to introduce polymer particles into the reaction chamber in a controlled manner as well as ignition means to continuously ignite gases in the reactor, promoting the burning reaction. In accordance with the subject method, the bulk of the polymer waste is substantially reduced and useful heat energy is recovered.
