Abstract
PURPOSE: To supply stable steam, by mounting a bleed or back air pressure control system, a pre-pressure control system and a change-over circuit, in these turbine facilities, which utilize steam, consisting of a pre-stage turbine, a plant that uses steam and an after-stage turbine.
CONSTITUTION: Only one side between the two of a bleed pressure control system 7 of a pre-stage turbine 2 and a pre-pressure control system 9 of an after-stage turbine 4 functions by means of a change-over circuit 10 of control systems. When the quantity F of a plant 3, which utilizes steam, that is used is little, a regulating valve 4a is locked at a location where the quantity F3 of swallowing is maximum by means of the pre-pressure control system 9, the after-stage turbine 4 is operated in the maximum output and steam pressure to the plant 3 is controlled by means of the bleed pressure control system 7 and a regulating valve 2a. When the quantity F of the plant 3 used increases, the opening of the regulating valve 2a becomes large by means of the bleed pressure control system 7, the control systems are changed over to the pre-pressure control system 9, the quantity F3 of swallowing is decreased by throttling the regulating valve 4a and the quantity of steam to the plant 3 is increased.
