FIELD: power engineering. SUBSTANCE: invention relates to turbocompressor sets to provide vacuum of higher degree by means of two-stage controllable supersonic back-up gas ejector at compressor inlet. Proposed exhaust plant has compressor installed on one shaft with free power turbine provided with inlet and outlet, and drive made in form of aircraft gas turbine engine whose outlet is connected with inlet of free power turbine. EFFECT: provision of vacuum of higher level owing to installation of two-stage controllable supersonic back-up gas ejector at compressor. 1 dwg
