Abstract

Un aparato de tratamiento de gas de chimenea que comprende un aparato de desnitración que tiene un catalizador de desnitración y un ducto que guía el gas de chimenea desde una caldera de combustión de carbón al aparato de desnitración, dicho ducto está conformado por un ducto horizontal, un ducto vertical conectado al ducto horizontal, y una tolva, en donde una placa de choque hace que las partículas de ceniza en el gas de chimenea choquen y caigan dentro de la tolva, y dicha placa de choque se suministra con el fin de inclinarse hacia el ducto horizontal mediante un ángulo de ajuste "a" (0º < a < 90º) con respecto al plano de abertura del extremo superior de la tolva.
