Condensates occuring in steam line are sent out of system by steam traps. Also depending on steam trap type, condensate which is sent out of system, is at the same temperature with the steam fed to system. Due to pressure difference between condensate line and steam line, some of condensate which is at the same temperature with steam, evaporates. This flash steam at low pressure is usually sent into atmosphere through air vent of condensate tank. The flash steam amount being sent out, changes depending on steam amount which is used at the process, model of steam trap and also robustness of steam traps in the system. The main object of the project is to ensure energy efficiency by bringing the flash steam (being sent out into atmosphere), into re-usable condition in the system.
