Flash steam is heat energy and treated water, and occurs when pressurized steam condensate is vented to atmosphere. Depending on the condensate pressure and the amount of condensate generated, flash steam loss could result in millions of BTUs of energy and gallons of treated water lost to atmosphere. There are many methods to capture this energy and treated water loss.
The key is to find a source to use the flash steam. One way is to use the flash steam to heat water. The flash steam could be directed to a water jet heater. The heated water could be used to preheat boiler make-up or other hot water needs in your facility.
