Collecting apparatus, condensation equipment, and collecting method

Condensation equipment comprising:

• a condenser of a steam turbine plant;
• a collecting apparatus configured to collect foreign matter mixed into condensate of the condenser, the collecting apparatus comprising:
• a foreign matter collector upstream of a condensate pump in a pipe connecting a drain port at a bottom portion of the condenser and the condensate pump to each other, the foreign matter collector including a first opening having a first dimension, and being configured to collect the foreign matter while allowing the condensate to pass therethrough;
• and
• an in-condenser collector in the condenser, the in-condenser collector including a second opening having a second dimension larger than the first dimension, and being configured to collect the foreign matter while allowing the condensate in the condenser to pass therethrough and flow toward the drain port;
• and
• a connecting portion at the pipe and to which a temporary pipe including an inertial collector and a permanent elbow pipe are selectively mountable as a portion of the pipe.

A collecting method of collecting foreign matter mixed into condensate of a condenser of a steam turbine plant, the method comprising:

• installing, upstream of a condensate pump in a pipe connecting a drain port at a bottom portion of the condenser and the condensate pump to each other, a first foreign matter collector including a first opening having a first dimension and configured to collect the foreign matter while allowing the condensate to pass therethrough;
• installing, in the condenser, an in-condenser collector including a second opening having a second dimension larger than the first dimension and configured to collect the foreign matter while allowing the condensate in the condenser to pass therethrough and flow toward the drain port;
• installing a temporary pipe including an inertial collector as a portion of the pipe, and
• performing a blowing-out operation in a state where the first foreign matter collector, the in-condenser collector, and the temporary pipe are installed.
