In a vacuum exhaustsystem, sealing steam to the turbine shaft labyrinth seals must be admitted to avoid loss of vacuum.
在真空排气系统中，必须引蒸汽到汽轮机主轴迷宫式密封，以防真空损失。

If the exhaustsystem is under a vacuum, the casing must be warmed by gradually introducing the steam, after opening the exhaust valve.
如果排气系统处于真空下，必须在打开排气阀后，逐渐引蒸汽来加热壳体。

Combined with methanol's indirect use in power system, methanol and dimethyl-ether steam reforming use gas turbine exhaust gas to constitute the chemically recuperative gas turbine cycle.
