Abstract

a presente invenção refere-se a uma turbina a vapor (1) que possui uma opção de resfriamento, na qual o vapor é retirado do canal de fluxo, o dito vapor resfriando o piso intermediário de compensação de impulso (16), sendo misturado com uma pequena quantidade de vapor vivo e sendo retornado ao canal de fluxo.
