The issues of organization of additional steam extractions in station collectors of the power plant from the flowing part of steam turbines to replace the reduction-cooling unit. The results of the implementation of additional steam extractions based on rotary valves with electromechanical and spring actuators are presented. The technique for determining the range of turbine operation modes with additional steam extraction is developed. The analysis of the economical use of additional steam extractions instead of reduction-cooling units is presented.
