Developments in or relating to a condensate recovery system

摘要

A condensate recovery system may comprise a plurality of drain lines for draining condensate from an associated steam plant. Each drain line may incorporate a steam trap and feeds into a common condensate return line running between the drain lines and a condensate receiver tank. The system further may comprise an acoustic sensor positioned along the common condensate return line, upstream of the receiver tank, for providing an acoustic output indicative of the collective steam loss through steam traps upstream of the sensor.
