Abstract: PURPOSE:To prevent disturbance on a drum water level by a method wherein a turbine bypassing valve has a function for controlling an outlet pressure of a regulation valve so as to control a differential pressure of the regulation valve. CONSTITUTION:A turbine bypassing valve 19 has a function for controlling a regulation valve with its outlet pressure being applied as a set value, a condition of differential pressure across the regulation valve is added to a steam condition 62 of an opened regulation valve and then a limitation of an opening or closing variation rate of the regulation valve is provided in reference to the differential pressure of the regulation valve 15. That is, when a complex power generating plant is energized, a secondary pressure at the regulation valve 15 is controlled under the turbine bypassing control so as to keep the outlet port pressure of the regulation valve 15 constant. A condition of differential pressure across the regulation valve is added to the steam condition 62 of an opened regulation valve and a limitation of a variation rate of a degree of opening of the regulation valve 15 is given as a function in reference to a condition of differential pressure of the regulation valve. With such an arrangement even in the case that the regulation valve 15 is opened in reference to a completion of the steam condition, the differential pressure across the regulation valve 15 is controlled, so that a flow rate of main steam and its pressure are well controlled and any disturbance can not be given to the drum water level.

Title: Refrigerating cycle
Inventor: NAKABO TADASHI
IPC: F25B1/00
Filed: 1988-04-27
Abstract: PURPOSE:To make it possible to extract saturated steam on the way to the heat exchange of a refrigerant vaporizer without lowering its efficiency, by heat-exchanging a refrigerant extracted on the way to the heat exchange of said refrigerant vaporizer with the refrigerant on a high pressure side. CONSTITUTION:The refrigerant which is subjected to excess cooling passing through a refrigerant heat exchanger 9 is introduced into a pressure reducing device 5 where it is subjected to insulation expansion, turned into low pressure and atomized saturated liquid, then flow into a refrigerant vaporizer 6. The saturated liquid which has flown into the refrigerant vaporizer 6 passes through the refrigerant vaporizer 6, removes the latent heat from the air blowing in a compartment, and turns into saturated steam. When the saturated liquid turns into saturated steam by about half inside the refrigerant vaporizer 6, the saturated steam is extracted outside the refrigerant vaporizer 6 and a vapor-liquid separator 8 installed on the way to the heat exchange of the refrigerant vaporizer 6, which removes the saturated steam on the downstream of the vapor-liquid separator 8 and produces saturated liquid. As a result, the refrigerant vaporizer 6 on the downstream of the vapor-liquid separator 8 makes it possible to improve the efficiency of heat exchange with the air blowing into the compartment and hence vaporize the saturated liquid in a short length of a refrigerant passage in the refrigerant vaporizer 6.
