What about FRQWDPLQDWLRQ"

If we reuse condensate, how many of us worry about putting FRQWDPLQDWHVGLUHFWO\LQWRWKHERLOHU"7KLVLVDJHQXLQH concern. Condensate can pick up contaminates, and contaminated feedwater can cause problems such as corrosion and carryover. 7KHUHDUHWZRYHU\HIIHFWLYHZD\V\RXFDQ RYHUFRPHWKLVFKDOOHQJH  7KH¿UVWLVWR¿WFRQGXFWLYLW\RUWXUELGLW\PHWHUV to an existing condensate return system to detect contamination. Whenever it is detected, the contaminated condensate is automatically dumped before it reaches the ERLOHU7KLVVROXWLRQFDQEH¿QHWXQHGDFFRUGLQJWRWKH nature of the operation. 2. Another approach is to recycle only the heat energy from contaminated condensate. This is done using heat exchangers, which ensure the heat is captured before the contaminated liquid is disposed of.

IF WE REUSE CONDENSATE, HOW MANY OF US WORRY ABOUT PUTTING CONTAMINATES DIRECTLY INTO THE BOILER?
