Abstract: This collecting apparatus collects foreign matter mixed in condensate in/from a condenser of a steam turbine plant, and comprises a first foreign matter collector and an in-condenser collector. The first foreign matter collector is provided on an upstream side of a condensate pump in a pipe connecting a drain outlet provided to the bottom portion of the condenser and the condensate pump to each other, has an opening having a first dimension, and collects foreign matter while passing the condensate therethrough. The in-condenser collector is provided inside the condenser, has an opening having a second dimension larger than the first dimension, and collects foreign matter while passing the condensate in the condenser therethrough toward the drain outlet.

Abstract: A method for cleaning a steam system including an intermittent operation processing step and a commissioning processing step are executed. The intermittent operation processing step includes: a no-load operation step in which a gas turbine is operated with no load, with a steam stop valve and a bypass valve closed; during the no-load operation step, a pressure accumulating step in which steam is accumulated in a pressure accumulation region; and, after the pressure accumulating step, an intermittent blowing step in which the bypass valve is opened, and steam in the pressure accumulation region is allowed to flow into a condenser. The commissioning processing step includes: a commissioning step in which the gas turbine is commissioned with the steam stop valve closed and the bypass valve open; and a continuous blowing step in which steam from a waste heat recovery boiler is allowed to flow into the condenser.

Abstract: In a storage compartment (124), storage spaces having different mist concentrations are formed such that effects of a mist is more efficiently utilized to provide a refrigerator with improved usability. The storage compartment (124) includes a first storage unit (164) that has a high mist concentration. The first storage unit (164) includes a spray device (167) and is disposed in a position outside an air path of cool air between a discharge port (152) through which the cool air flows in from outside the storage compartment (124) and a suction port (149) through which the cool air is discharged to outside the storage compartment (124). Thus, mist concentration inside the first storage unit (164) can be increased.
