Abstract

TURBINA A VAPOR E MéTODO PARA OPERAR UMA TURBINA A VAPOR. A presente invenção refere-se a uma turbina a vapor (1) com uma caixa externa (2) e uma caixa interna (3), onde a caixa externa (2) e a caixa interna (3) possuem um canal de alimentação de vapor fresco (10), onde um rotor (5) possuindo um êmbolo de compensação de pressão (4) compreendendo diversas pés móveis (7), apoiado de modo giratório, está disposto dentro da caixa interna (3), e onde a caixa interna (3) possui diversas pás fixas (8) que estão dispostas de tal modo que ao longo de um sentido de corrente (11) se forma um canal de corrente (9) com diversos estágios de pás que possuem respectivamente uma série de pás móveis (7) e uma série de pás fixas (8), sendo que a caixa interna (3) possui um canal de refluxo (14) que é executado como tubo de comunicação entre um espaço (15) entre a caixa interna (3) e a caixa externa (2) e o canal de corrente (9) depois de um estágio de pás, e que a caixa interna (3) possui um canal de admissão (16) executado como um tubo de comunicação entre o espaço (15) entre a caixa interna (3) e a caixa externa (2) e uma antecâmara do êmbolo de compensação de pressão (12) entre o êmbolo de compensação de pressão (4) do rotor (5) e da caixa interna (3).
