FIELD: heat-power engineering; peak polyunits including power units provided with pipe lines of cross members of boilers. SUBSTANCE: mounted in pipe line of transverse coupling is quick-acting automatic stop valve whose actuating mechanism operates by signal from electric contact pressure gauge. Units are of the condensing type with supercritical parameters of live steam and heat introducing type with subcritical parameters of live steam. Pressure gauge is mounted on transverse coupling pipe line in area of subcritical parameters of steam. EFFECT: enhanced efficiency.
