FIELD: thermal power stations. SUBSTANCE: turbogenerator has turbine casing and generator stator, turbine and generator rotors, speed governing system incorporating delivery header, drain header, working medium (water) tank, and pumps, plain bearings, lubricating system for plain bearings incorporating delivery and drain headers. Delivery header of speed governing system and that of bearing lubricating system are interconnected by means of pipeline incorporating pressure-reducing valve and water-to-water cooler arranged in tandem; drain header of speed governing system and that of bearing lubricating system are interconnected by means of pipeline; plain bearings are multilayer flexible structures made of elastically deforming composite metal- plastic material. Due to such design friction power loss in water-lubricated bearings is reduced by 8-10 times; there is no need in expensive mineral and synthetic oils for their lubrication. EFFECT: improved environmental friendliness, reduced fire hazard, and enhanced efficiency of power units. 1 dwg
