Single shaft turbine set using two working materials - comprising steam and water and, in the low press. section, methyl propylene glycol-water azeotrope

摘要

A single shaft turbine set uses two working materials, that in the first stages being water/steam whilst them material used in the second (low pressure) section of the machine is an azeotropic mixt. of 53% methylene propylene glycol with 47% water. For power turbines of karge outputs. The two-material system allows a redn. in the size of the low-pressure section of the machine. The methylene propylene glycol-water mixt. is non-inflammable, of low toxicity and has good thermal and thermodynamic properties.
