<p>The mass of tyres placed in a reaction tower (1) and closed off from the exterior is ignited at the bottom by means of a burner (10), and when the pressure in this tower reaches a predetermined value the said mass is heavily compressed and the gases resulting from the process are evacuated via an electric fan (27) and directed to at least one condensing and cleaning unit (100). As a result of the compression and of the fact that the process is performed in an oxygen-lean environment, the tyres undergo a process of autopyrolysis, at an average operating temperature of about 150 DEG C, resulting in the formation of hydrocarbons and with a limitation of pollutants that are eliminated in the final filtering unit (100). A separate lower circuit (41, 43) allows for the possibility of controlling a uniformly distributed admission of ambient air over the base of the reaction tower. <IMAGE></p> |
