Choosing Flash Vessel

1- Maximum condensation amount is required to obtain maximum flash steam.

For this reason, the capacity of steam traps must be selected carefully, taking into consideration the counterpressure. It should also be noted that in systems where temperature control valves are used, the valve will be closed and the pressure will drop.

2- The amount of use of flash steam systems must be equal to the amount of flash steam.

Steam can be provided by pressure drop from a higher pressure steam line when the flash steam is missing. If flash steam is excessive, some of the flash steam must be thrown out. Also, since the flash used in heating will not be needed in summer, a heat recovery system will not be necessary.

Therefore, the amount of flash steam required must be prepared.

3- It is beneficial if the system to be used with flash steam is close to the outlet of the condensate at high pressure. The transport of low-pressure condensate requires large diameters and will increase investment costs. In addition, the heat losses that will occur on large pipe diameters will reduce the benefits of flash buckets.
