FLASH STEAM RECOVERY

Thursday, Day 12/02/2026

When the pressure of saturated condensate is reduced, a portion of the liquid “flashes” to low-pressure steam. Depending on the pressures up stream, the flash steam contains normally 3% to 50% of the energy content of the original condensate. Almost cases, condensate receivers the flashing steam is vented to atmosphere and its energy content lost.

Typical popular case

Proposal recovery solution

These-energy possibility recovered with flash vapor recovery by using a plate heat exchanger installed in the vent pipe.

Example:

Tank vent to atmostphare with pipe Ø114, estimated steam vent out from condensate tank 184 kg/hr @ 0.1 barg (equivalent 202 kg/hr @ 7 barg saturated steam from boiler)

Steam cost 30.5 $ / ton (equivalent 700,000 VND/ ton) → 0.0305 $/kg (equivalent 700 VND/ kg)

Saving $= 0.0305 x 202 = 6.161 $/hr

Day Saving = 6.161 x 24 (hr) = 147.864 $/day

Month Saving = 147.864 x 30 (day) = 4,435.92 $/month

Year Saving = 4,435.92 x 12 (day) = 53,231.04 $/year (equivalent 1,277,544,960 VND/year)

Advantages of inverted bucket steam traps compared to float-type steam traps

When you need a steam trap with high water hammer resistance, durability in high-pressure systems, and reliable operation under conditions of severe impact or surge loads.
Pressure reducing valves are used for saturated steam and pressure reducing valves are used for liquid fluids

Pressure regulating valves (also known as pressure reducing valves) are crucial devices in industrial and commercial piping systems. Their primary function is to maintain a stable downstream pressure, regardless of upstream pressure fluctuations or changes in flow rate. Depending on the application, selecting the appropriate valve is essential to ensure efficient and safe operation of the valve and the entire system.
How Does a Direct Pressure Reducing Valve for Saturated Steam Work?

At startup, the pressure regulating bolt is in the loosen state, the inlet steam pressure and the valve seat spring are in the closed state. We begin by turning the pressure regulating bolt on top of the valve clockwise. The bolt moves linearly, pushing the spring downwards, simultaneously lowering the valve diaphragm, controlling the valve to open, and the fluid and outlet pressure begin to increase. The pressure inside the valve body pushes the diaphragm upwards, balancing the spring force. The pressure after the valve increases simultaneously until it reaches the set pressure value, at which point the valve begins to close gradually, preventing the pressure after the valve from exceeding the set threshold.

WHY USE STEAM?

There are three main forms of energy used in industrial processes: electricity, direct heat, and steam.
