Class Н.1: single-casing turbines feature straight steam flow arrangement of low-pressure live steam the turbine from 1.4 to 2.2 MPa (14-22 kgf/cm2), capacity range is from 10 to 60 MW, last stage blade with a length from 550 to 660 mm (22-26 in) can be used. 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 body is made as welded or welded and forged.
