Abstract

resumo patente de invenção: "turbina parcial de baixa pressão". a presente invenção refere-se a uma turbina parcial de baixa pressão de fluxo duplo (1), em que o vapor de descarga do primeiro fluxo (2) e o vapor de descarga do segundo fluxo (3) são defletidos em uma direção comum dentro do alojamento externo (9) e assim um fluxo de saída axial ocorre.patent summary: "low pressure partial turbine". The present invention relates to a dual low flow partial pressure turbine (1), wherein the first flow discharge steam (2) and the second flow discharge steam (3) are deflected in a common direction within. from the outer housing (9) and thus an axial outlet flow occurs.
