Abstract
In the operational cycle of a post-combustor (1), through a suction line (2) high temperature smoke is withdrawn and is subjected to a first pre-treatment for the abatement of some of the polluting substances by way of a measuring device (4) that releases substances with an ammonia and/or urea base on the supply lines (5) the treated smoke is inserted into the reactor (6) at various levels. The first injection is at a low level, through a chamber (7), allowing the fluidification of the first layer (9) of the fluidized bed in which is immersed the first stage of the superheater (10). The second injection is placed in the area (11) where the bed is boiling and the spaces between the solid particles are more ample. In the third zone (12) the bed is circular and the spaces are vast. The solid particles exit the reactor and are sent to the separator (14) that recycles into the reactor (6) the larger of the solid particles while the pieces that are finer, that are considered exhausted, are distanced through a suction device (17) that send, through a tube (18), to a conventional smoke abatement and filtering system (19) from which, through the aspirator (21) the are sent on there way (22).<IMAGE>
