Title: Control method of steam temperature
Inventor: AOKI SHIGEO
IPC: F01D17/24
Filed: 1980-11-28
Abstract: PURPOSE:To control the steam temperature, by controlling the opening between an outlet drain valve and an inlet drain valve of a steam generator based on the deviation of the steam temperature between the outlet of the steam generator and the inlet of a steam turbine. CONSTITUTION:The opening of an output drain valve 9 of an overheater 3 is decided by using the deviation DELTAt between the steam temperature T2 at the inlet of a turbine 5 and the steam temperature T1 at the outlet of the heater 3 as a parameter. The valve 9 is operated in the opening direction by an arithmetic controller 11 in the case of DELTAt>0, and the control is carried out based on a program so that an opening corresponding to a valve 10 is obtained when the pressure of a drum (not shown in the diagram) is attained higher than a prescribed level. In the case of DELTAT<0, the valve 9 is not operated until the drum pressure becomes higher than the prescribed level, and the programmed control is carried out by the controller 11 to obtain an opening corresponding to that of the valve 10 after the drum pressure is attained higher than the prescribed level. For the programmed control given when the drum pressure becomes higher than the prescribed level, a prescribed increase factor of temperature is secured by simultaneously controlling both valves in the opening direction.
