FIELD: power industry.
SUBSTANCE: invention relates to power engineering, in particular to the method of greasing of expansion machines according to which from the evaporator the working medium is supplied which contains lubricant, and also a part of lubricant is separated from the working medium, while the working medium is supplied into the expansion machine with decreased content of the lubricant means as a result of separation of at least part of the lubricant. The lubrication system, and also the steam power plant which comprises the lubrication system according to the invention are also presented.
EFFECT: improvement of efficiency of expansion machine greasing method.
