.DELTA. ABSTRACT OF THE DISCLOSURE In the operation of a turbine system composed of apparatus (6,12,14,16) for generating steam and a turbine first stage (4) having inlet nozzles connected to be supplied with steam from the steam generating apparatus (6,12,14,16), the steam generating apparatus (6,12,14,16) being composed of a cascade arrangement Or a boiler (6) producing steam at a selected pressure which has an assigned lower limit value, a primary superheater section (12), one or more division valves (14) presenting a steam flow passage having a controllable cross-sectional area, and a secondary superheater section (16) connected between the division valves (14) and the inlet nozzles, a method for reducing the output of the system at low load levels comprising: reducing the cross-sectional area of the steam flow passage presented by the division valves (14): and increasing the rate at which heat is supplied to the steam in the secondary superheater section (16) by an amount coordinated with the reduction imparted to the cross-sectional area of the steam flow passage by the reducing step.
