ABSTRACT:
A steam distribution and condensate recovery system for pulp dryers has a plurality of steam heat exchangers. The system includes a steam feed conduit adjacent one end of each heat exchanger. A condensate conduit is adjacent the one end of each heat exchanger. A first connecting conduit is positioned adjacent the one end of each heat exchanger and connects each heat exchanger to the steam feed conduit. A second connecting conduit is placed adjacent the one end of each heat exchanger and connects each heat exchanger to the condensate conduit. Preferably the connecting conduits includes expansion loops. The expansion loops extend away from heat exchanger and away from access doors adjacent each heat exchanger.
