Vacuum system for power station condenser - has steam separator on outlet of liquid ring pump liquid separator

摘要

The vacuum(2) in the condenser is maintained by a two stage pump consisting of an ejector(4) and a liquid ring vacuum pump(5). The discharge of the latter is taken to a liquid separator(6) from which the liquid is returned to the pump and the air blown off (14). The air from the liquid separator is used to drive the ejector(4). There is a connection(10) between them for this purpose. A steam separator(16) is put in this connection on the outlet of the liquid separator. This enables air from the liquid separator to be used as a driving medium without loss of efficiency.
