Thermax Atmospheric Flash System (TAFS)

The Thermax atmospheric flash system is designed to efficiently recover the low-pressure flash steam generated when high-pressure condensate is discharged into a lower-pressure (atmospheric) receiver.

By capturing this otherwise wasted energy, it provides a valuable source of low-pressure steam for secondary heating applications, significantly reducing overall plant energy consumption and contributing to substantial fuel savings and improved system efficiency. When high-pressure condensate (e.g., from a main steam line trap or process equipment) is released into an atmospheric condensate tank, a portion of it "flashes" into low-pressure steam due to the sudden pressure drop. This flash steam, though low in pressure, still contains significant energy that is often simply vented to the atmosphere, representing a considerable waste. The Thermax atmospheric flash system captures this flash steam in a dedicated flash vessel. This recovered low-pressure steam can then be directed to other processes that require lower-grade heat, such as heating boiler feed water, drying processes, or other low-pressure applications. This system is a simple yet effective way to optimise energy utilisation within a steam network.

 Key Industries / Applications:

• Industries: All industries that use high-pressure steam and have subsequent low-pressure heating demands, such as chemical, textile, food and beverage, paper, and power generation
• Applications: Recovering flash steam from high-pressure condensate lines (e.g., from main steam headers, high-pressure process equipment, or steam traps) and utilising it for boiler feed water heating, hot water tanks, air pre-heaters, or other low-pressure process loads
