Abstract

"PROJETO DE ROTOR COM VEDAçõES DUPLAS PARA PREAQUECEDORES DE AR VERTICAIS". Método para adicionar vedações axiais (56') e vedações radiais (46') adicionais dentro de preaquecedores de ar existentes. As cestas de transferência de calor (40), as vedações radiais (46), as vedações axiais (56), e as grades (62) instaladas são todas removidas do preaquecedor de ar. As placas de junção (64, 66) existentes são modificadas, se estas forem reutilizadas, ou substituídas por novas placas de junção (65, 67). Uma placa de diafragma intermediária (60) está posicionada dentro de cada compartimento (36) original e montada nas placas de junção (64, 66). As barras de suporte de vedação axial de extremidade quente e fria adicionais (52', 54'), são montadas no envoltório do rotor (34) e na placa de diafragma intermediária (60). As vedações axiais (56, 56') são instaladas sobre as barras de suporte de vedação axial originais e adicionais (52, 54, 52', 54') e as vedações radiais (46, 46') são instaladas sobre as bordas axiais das placas de diafragma intermediárias e originais (38, 60).
