Abstract

APARELHO DE LIMPEZA PARA A LIMPEZA DE UMA BICA DE SMELT (FUNDIDO) DE UMA CALDEIRA. Um aparelho de limpeza para a limpeza de uma bica de smelt de uma caldeira é provido. A caldeira inclui uma parede de caldeira que define uma janela de saída para descarga de smelt fundido e a bica de smelt é posicionada com respeito à janela de saída de modo que o smelt fundido seja capaz de fluir ao longo da bica de smelt. O aparelho de limpeza inclui uma ferramenta de limpeza que tem um par de lâminas de limpeza geralmente alinhadas com as respectivas paredes laterais da bica de smelt e um conjunto de atuação configurado para mover as lâminas de limpeza de uma primeira posição para uma segunda posição. Cada uma das lâminas de limpeza se encaixa nas respectivas paredes laterais da bica de smelt para desalojar os depósitos de smelt endurecidos dali, quando as lâminas de limpeza estiverem na segunda posição.
