Abstract

Patente de Invenção<B>"SISTEMA DE QUEIMA TANGENCIAL DE BAIXO NO~ x~ INTEGRADO"<D>. Sistema de aquecimento tangencial integrado de NO~ 2~ inferior (12) que é particularmente adequado para uso com fornos aquecidos por combustível sólido pulverizado (10) e um método de operação de um forno aquecido por combustível sólido pulverizado (10) equipado com um sistema de aquecimento tangencial integrado de NO~ 2~ inferior (12). O sistema de aquecimento tangencial integrado de NO~ 2~ inferior (12) quando assim empregado com um forno aquecido por combustível sólido pulverizado (10) é capaz de limitar as emissões de NO~ 2~do mesmo em menos de 0,15 ab/10^ 6^ BTU, enquanto ainda mantém as emissões de carbono em poeira de cinzas em menos do que 5% e as emissões de CO em menos de 50 ppm. O sistema de aquecimento tangencial integrado de NO~ 2~ inferior (12) inclui dispositivo de suprimento de combustível sólido pulverizado (62), pontas (60) de boquilha de injeção de combustível sólido pulverizado com ligação de chama, boquilhas de queima concêntrica, ar com excesso de fogo agrupado compacto (98,100) e ar com excesso de fogo separado em múltiplos estágios (104,106).
