Abstract

método para controlar infiltração e exfiltração de gases através de um eixo de uma turbomáquina e sistema de geração de potência trata-se de métodos e sistemas para controlar a infiltração do ar ambiente em, e exfiltração do gás de processo fora de , um sistema orgânico de rankine. um primeiro mecanismo de vedação, por exemplo, uma vedação de gás seco dupla, pode ser usada para impedir a exfiltração do gás de processo quando o sistema orgânico de rankine está em operação. um segundo mecanismo de vedação, por exemplo, uma vedação de anel estático inflável, pode ser usado para evitar a infiltração do ar ambiente quando o sistema orgânico de rankine está paralisado. um ou mais sensores de pressão pode(m) ser fornecido(s) no sistema orgânico de rankine para determinar se, por exemplo, a infiltração do ar ambiente ocorreu e uma depuração do sistema é necessária.
