Epätiivistymät

Epätiivistymät are a Finnish term referring to non-condensable gases in a closed system, particularly in steam systems. These gases, such as air, nitrogen, and combustion products, can accumulate in areas where steam is expected to be, hindering the efficient transfer of heat. They are called "non-condensable" because they do not readily turn into liquid when cooled, unlike steam.

The presence of epätiivistymät can significantly reduce the effectiveness of heat exchangers, radiators, and other steam-powered equipment. They create insulating layers that prevent direct contact between the steam and the heat transfer surfaces. This leads to lower operating temperatures, increased energy consumption, and potential equipment damage due to uneven heating.

Effective management of epätiivistymät is crucial for optimal performance and longevity of steam systems. This is typically achieved through the use of steam traps, which are designed to automatically vent non-condensable gases and condensate while retaining steam. Proper system design and regular maintenance, including checks of steam trap functionality, are essential to prevent the buildup of epätiivistymät and ensure efficient operation. Identifying and removing these gases is a key aspect of steam system optimization and energy saving.
