Abstract

"APERFEIçOAMENTO DE CAMPO DE FLUXO NO ESPAçO DE ALIMENTAçãO DE UM LEITO FLUIDIZADO" Uma estrutura de espaço de gás para dispositivo de leito fluidizado, incluindo uma estrutura, definindo uma ou mais paredes laterais e de base, em torno do espaço de câmara e dispositivos, definindo uma entrada de gás para a câmara, arranjados de tal forma que o gás flua geralmente para cima para o interior da câmara, a partir da entrada. A estrutura inclui dispositivos de distribuição, se sobrepondo à referida câmara e possuindo múltiplas aberturas através das quais o gás deixa a câmara para formar um leito fluidizado, acima dos dispositivos de distribuição. Dispositivos se encontram dispostos entre a referida entrada e os referidos dispositivos de distribuição, para expandir ou difundir o fluxo de gás entre as aberturas. O dispositivo de difusão de fluxo de gás possui uma pluralidade de aberturas para o fluxo do gás através das mesmas e onde o referido dispositivo de fluxo de gás e as referidas aberturas de fluxo são dimensionadas e dispostas para reduzir de forma substancial a velocidade de fluxo cruzado do referido gás nas referidas aberturas.
