FIELD: thermal-to-electrical energy conversion. SUBSTANCE: radial turbine has opposing-rotation wheels and generator whose magnets are secured on turbine wheels and stator coils, on casing. Steam is supplied to turbine wheels over stator whereon wheels are rotating and conveyed through guide vanes to first stage. High-pressure section is separated from bearing assembly by labyrinth seal. Height of turbine wheel blades may be different and vary from first to last stages either stepwise or in stepless manner along tilted straight or curved line. Bearings are provided with forced lubricating system that also functions to cool them. Bracing device is incorporated to take high-pressure breaking loads. EFFECT: enhanced efficiency of turbine. 6 cl, 4 dwg
