Abstract

"APARELHO PARA REMOçãO DE ACúMULOS DE PóS DE UM ALTO-FORNO". A presente invenção se refere a um aparelho para quebrar e destacar mecanicamente acúmulos de pós criados por gases de processamento e que ficam acumulados sobre as paredes internas de um alto-forno de fusão em suspensão e/ou de uma caldeira de calor residual permanentemente conectada ao alto-forno de fusão em suspensão. De acordo com a invenção, sobre a superfície externa (7, 13) da parede de um alto-forno de fusão em suspensão (1) e/ou uma caldeira de calor residual (6), na vizinhança do ponto de conexão (5) entre o alto-forno de fusão em suspensão e a caldeira de calor residual, é instalado pelo menos um dispositivo percussor (8, 14), pelo que pode ser criado um efeito de impacto mecânico e um contato mecânico entre o aparelho (8, 14) e pelo menos um dos acúmulos de pós (12, 19).
