What Is the Steam Condensate Flash Steam Recovery Calculator?
When high-pressure condensate discharges through steam traps into a lower-pressure receiver or flash vessel, the excess sensible heat instantly boils a portion of the water into flash steam.
Instead of venting this flash steam to the atmosphere, routing it to a low-pressure header or deaerator recovers substantial thermal energy and reduces boiler fuel consumption.
This calculator computes the flash steam percentage, hourly flash steam production in kg/h, remaining liquid condensate, and recovered thermal energy power in kW.
How Does the Steam Condensate Flash Steam Recovery Calculator Work?
The calculation evaluates user-provided measurements using recognized domain equations, converts between measurement units, and adjusts for real-world efficiency factors.

When Should You Use This Calculator?
Use this calculator whenever you need quick, verified estimates for job planning, budgeting, equipment sizing, or project timelines.
Assumptions & Limitations
- Flash vessels must be sized with low upward vapor velocity (typically < 1.0 - 1.5 m/s) to prevent liquid droplet carryover into the flash steam piping.
- Flashing reduces remaining condensate temperature, making it easier for return pumps to operate without cavitation.
