FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. Cogeneration power plant is made on the basis of a steam screw machine, on the shafts of which there are double end seals. Locking liquid in the seals is water from a condensate tank, which is delivered into the seals with the help of a booster pump and which removes heat of friction and the heat passing along the shafts of the steam screw machine. Heated water from the seals is delivered to the inlet of the feed pump.
EFFECT: invention increases efficiency of a common use cogeneration power plant.
