Class М.1: single-casing turbines with straightsteam flow arrangement for pressure from 2.0 to 4.5 MPa (20-45 kgf/cm2), capacity range is from 5 to 16 MW. The turbine is assumed with both the radial exhaust to one water-cooled condenser and the axial exhaust to the air cooling condensing unit. The turbine is installed on a single frame and delivered as single-module assembly. The turbine features the possibility to organize single-stage controlled heat extraction with a capacity of up to 20 Gcal/h, as well as uncontrolled industrial steam bleeding for auxiliaries with a capacity of up to 40 t/h.
