Recovery of Flash Steam

When a steam trap purges condensate from a pressurized steam distribution system to ambient pressure, flash steam is produced. The energy can be recovered by a heat exchanger and used for space heating or feed water preheating. The potential for this measure is site dependent. Sites using multi pressure steam systems can route the flash steam formed from high-pressure condensate to reduced pressure systems.

Recovery of Flash SteamCosts & Benefits

Parent Process: Cross Cutting Technology
Energy Savings Potential

Depending on the pressures involved, the flash steam contains approximately 10% to 40% of the energy content of the original condensate.

CO2 Emission Reduction Potential
Costs

The economics of heat recovery projects are most favorable when the waste steam heat content is high and the flow is continuous. Average payback time for this measure is around 9 months.
