Abstract

"SISTEMA DE TRATAMENTO DE EMISSãO". A presente invenção refere-se a um sistema de tratamento de emissão para a remoção de NO~ x~ de um gás de combustão que inclui um elemento de desvio 34 que fecha a chaminé 22 em uma posição intermediária às extremidades de entrada e saída. Um módulo de componentes principais 26 inclui um primeiro sub-módulo, tendo uma entrada e um segmento de redução SCR 28, um segundo sub-módulo, tendo um segmento de trocador térmico 30, e um terceiro sub-módulo, tendo um ventilador de corrente ID 32 e uma saída, formando uma trajetória de fluxo de gás de combustão que se estende da entrada para a saída. A tubulação de entrada 40, que fica em comunicação fluida com a chaminé 22 em uma posição intermediária à extremidade de entrada da chaminé 22 e o elemento de desvio 34, provê uma passagem a partir da chaminé 22 para a entrada. Uma tubulação de saída 44, que fica em comunicação fluida com a chaminé 22 em uma posição intermediária ao elemento de desvio 34 e à extremidade de saída da chaminé 22, provê uma passagem a partir da saída para a chaminé 22. Um subsistema de adição de amónia 54 injeta vapor de amónia na tubulação de entrada 40.
