Abstract

"BOCAL DE DESCARGA CONFLUENTE VENTILADO". Um bocal de descarga (38) inclui um conduto externo (50) circundando um conduto interno (36). o conduto interno (36) inclui uma saída principal (46), e uma fileira de aberturas (48) espaçadas a montante do mesmo. o conduto externo (50) inclui uma fileira de entradas (52) em uma extremidade avançada, uma saída auxiliar (54) em uma extremidade traseira, e circunda o conduto interno (36) sobre as aberturas para formar um canal de desvio (56) terminando na saída auxiliar (54). Uma fileira de flapes (58) são articulados em extremidades a montante para cobrir e descobrir seletivamente as aberturas (48) a fim de seletivamente desviar uma porção de fluxo de descarga proveniente do conduto interno (36) através do conduto externo (5) em correntes confluentes provenientes das saídas tanto principal como auxiliar (46, 54). Quando o flape (58) cobre as aberturas, a entrada (52) ventila o canal de desvio (56) e descarrega fluxo através da saída auxiliar (54).
