Remove Condensate with Minimal Air Loss
Removing condensate is important for maintaining the appropriate air quality level required by end uses. However, significant compressed air (and energy) losses can occur if condensate removal is done improperly. Excess compressed air loss during condensate removal can occur due to several factors. Following shows several condensate removal methods and the characteristics of each method. Manual operation: Operators manually open valves to discharge condensate. Depends on people opening valves at the appropriate time for the necessary amount of time. Often leads to excess loss because air escapes when the valves are left open to drain the condensate. Level-operated mechanical float traps: Use a float connected by linkage to a drain valve that opens when an upper setting is reached and closes when the drain is emptied. Require considerable maintenance. Are prone to blockage from sediment in condensate. Are prone to getting stuck in open position (leak excess air) and in the ...
