Condensate Recovery & Flash Steam Module
Efficient Recovery of Hot Condensate and Usable Flash Steam
What Is a Condensate Recovery & Flash Steam Module?
A Condensate Recovery & Flash Steam Module is an integrated system designed to collect hot condensate generated after steam transfers its heat to process equipment and recover usable energy from the resulting flash steam.
Instead of discharging hot condensate to drain, the system can return it toward the boiler feedwater or condensate circuit for reuse.
When high-pressure condensate enters a lower-pressure environment, a portion of the condensate can vaporize into steam. This secondary steam, known as flash steam, can be separated and directed toward a suitable low-pressure steam application.
How Does a Condensate Recovery System Work?
1. Steam Heating
Steam supplies heat to process equipment.
2. Condensate Formation
Steam condenses after transferring its heat.
3. Condensate Collection
Hot condensate flows into the condensate return system.
4. Pressure Reduction
The condensate experiences a pressure reduction where flash steam can form.
5. Flash Steam Separation
The flash steam is separated from the remaining condensate.
6. Flash Steam Recovery
Recovered flash steam is directed to a suitable low-pressure application.
7. Condensate Return
The remaining hot condensate is returned toward the boiler or feedwater system.
What Is Flash Steam Recovery?
Flash steam recovery occurs when hot condensate at a higher pressure is released into a lower-pressure vessel. Due to the pressure drop, part of the hot condensate evaporates into steam.
A flash steam module separates this steam from the remaining condensate. The recovered flash steam can then be used for suitable low-pressure heating applications, while the remaining condensate continues through the recovery system.

Frequently Asked Questions
What is a condensate recovery system?
A condensate recovery system collects hot condensate from steam-consuming equipment and returns it to the boiler or feedwater system for reuse.
What is flash steam?
Flash steam is the portion of hot condensate that rapidly changes into steam when high-pressure condensate is released to a lower-pressure environment.
What is the purpose of a flash steam module?
A flash steam module separates and recovers usable flash steam from hot condensate so it can be used in suitable low-pressure applications.
Does condensate recovery save energy?
Yes. Returning hot condensate reduces the energy required to heat incoming boiler feedwater and can also reduce water and treatment requirements.
Can flash steam be reused?
Yes. Recovered flash steam can be supplied to suitable low-pressure steam consumers, depending on the available steam pressure and process requirements.
Can the system be customized?
Yes. A custom condensate recovery unit can be designed according to steam pressure, condensate load, flash steam requirements, boiler capacity, and plant layout.
