Abstract

"FORNALHA PARA UMA CALDEIRA DE RECUPERAçãO". Expõe-se uma disposição para fornecer uma forma de jato de ar à fornalha de uma caldeira de recuperação, onde a fornalha tem uma parede frontal, uma parede traseira e paredes laterais. Dispositivos de pulverização de licor negro ficam dispostos nas paredes da fornalha em um ou vários níveis da fornalha. Uma pluralidade de orifícios de ar fica distribuída em várias elevações horizontais para a introdução de ar dentro da fornalha a partir de um suprimento de ar. Na disposição para os fluxos de ar secundário, pelo menos dois níveis de ar horizontais em elevações diferentes ficam dispostos acima dos níveis principais inferiores e abaixo do pulverizador de licor negro. Ar secundário é fornecido a partir de duas paredes opostas. Os orifícios de ar secundário em cada uma das ditas primeira e segunda elevações compreendem orifícios de ar para cada elevação horizontal que projeta um padrão de amplos jatos de ar dentro da fornalha a partir das ditas paredes apostas e os ditos orifícios de ar secundário compreendem ainda uma pluralidade de orifícios de ar secundário em pelo menos uma das elevações que projetam jatos de ar menores para dentro da fornalha.
