Flue Gas - an overview | ScienceDirect Topics

Flue gas condensation systems are designed in two ways: as a single-stage recuperative shell and tube heat exchanger and two-stage systems with the first stage of the cooling recuperator (dry economizer, DE) and the second stage in the form of scrubber condensing water vapor and cleaning the flue gas (wet economizer, WE). An example of the first type is the installation …

Best Way to Prevent Chilled Pipe "Sweating" or Condensation

When spray foam insulation consistently gets wet from a sweating pipe, it loses its insulation value and shape. The spray foam insulation will need to be replaced much earlier than expected, and the component it was meant to protect could need replaced as well. This is why installing the proper insulation the first time can save building ...
