ResumoEste trabalho tem como objetivo descrever as ações que foram tomadas pela TKCSA com o objetivo de restabelecer a capacidade operacional plena do Gasômetro (BFG), pela sua estabilidade e, por conseguinte a sua continuidade operacional. Desde seu start-up, ambos os Gasômetros apresentaram vários problemas que impediram sua operação em plena capacidade; provocaram várias paradas para realinhamento, rebalanceamento, bem como repopeamento. Estas ocorrências interferiram fortemente na Geração de energia do complexo, devido a instabilidade dos Gasômetros, causada por irregular movimentação do pistão, provocando sua descentralização e desnivelamentos fora das tolerâncias aceitáveis, o que levou a TKCSA a limitar a operação dos Gasômetros e, mesmo assim ; sempre que descentralizava e ou desnivelava, era necessário novos ajustes (repopeamento e rebalanceamento). Tais eventos nestes importantes equipamentos, levaram a CSA a tomar várias ações conforme preconiza o IGEM (Instituition of Gas Engineer) passando por reparos estruturais e culminando com a troca do sistema de selagem dos Gasômetros. Palavras-chave: Segurança; Gasômetro; Repopeamento; Rebalanceamento; Gás de alto forno "BFG". RE-ESTABLISHING OF OPERATIONAL RELIABILITY OF THE TKCSA´S BLAST FUNNACE GASHOLDER AbstractThis work aims to describe the actions that were taken by the CSA in order to reestablish the full operational capacity of the Gasholder (BFG), for its stability and therefore its operational continuity. Since its start-up, both Gasholders had several problems that impeded its full operational capacity; caused several stops for realignment, rebalancing and repoping. These occurrences strongly interfere in the power generation of the complex, due Gasholders´s instability , caused by irregular movement of the piston, causing its decentralization and unbalancing out the acceptable tolerances, leading to TKCSA to limit the operational capacity of the Gasholders, and even then; whenever that centralization was out and or balance was out, it was necessary new settings (repoping and rebalancing). Such events at this important equipment, led the CSA to take various actions as recommendation of IGEM (Instituition of Gas Engineer) undergoing structural repairs and culminating with the change of the Gasholders membrane (seal system).
