boiler evaporator

A boiler evaporator or boiler pressure vessel is a tool used to lower the steam flow into the boiler's economizers. There are several ways to accomplish this. To cool the evaporator, for instance, you could install a heat exchanger as well as an air separator or a water separator.

Flow of steam through the economizers

An economizer may start to steam when it is cold starting up or when the water level is low. This is as a result of the water not being heated to boiling. Several strategies must be used to stop this.

Economizers are heat exchangers that heat water to the boiling point using only one flow path. A decrease in water flow or the presence of trapped vapor can both cause steaming. Boiling in the economizer can cause issues like hammering and fatigue.

Reduced water flow is the most effective way to stop an economizer from steaming. The by-pass line can be used for this. The by-pass line is a conduit that connects the bypass valve to the economizer output conduit. Some of the steam in the economizer will condense as the pressure inside the device rises.

To increase the pressure, an economizer control valve can also be added. But doing so necessitates more power and risks valve failure. The controller also needs to have the ability to process data for the by-pass line.

Usually, during transient conditions, a by-pass line is used to reduce the water flow in the evaporator. Due to the potential for a significant pressure drop, this could also present a challenge.
