Abstract (en)

[origin: JPH0281906A] PURPOSE: To shorten length of a turbine rotor by dividing and arranging extraction function and extraction pressure adjustment function. CONSTITUTION: An extraction pipe 10 is arranged in the middle point of a steam turbine 1 having 7 stages. On the other hand, a servo controlled valve 11 is arranged in an exhaust pipe 9. And, a servo control circuit 12 includes a means that compares a standard signal generated by a set point generator 13 with output signals generated by a pressure sensor 14 positioned in the extraction pipe 10. So, the extraction is controlled in a predetermined range of extraction rate by controlling the servo control valve 11 with the servo control circuit 12. As the extraction function and the extraction pressure adjust function are physically divided, length of the turbine rotor is shortened.
