Critical Steam System Fixes

Why the Removal of Noncondensable Gases and Air Is Critical in a Steam System Air and noncondensable gases are one of the major problems in a steam system that can cause production problems for a plant’s operation. Air in a steam system dramatically reduces the system’s performance. For example, the thermal conductivity of air is 0.000049, compared with 0.002 for water, 0.20 for iron, and 0.96 for copper. Not removing air and noncondensable gases from the steam system can reduce heat transfer efficiencies by 21 percent or more depending on the air concentration in the steam system. Since air is one of the greatest insulators, a major steam operation objective is eliminating air in a steam system.
