Is it possible to omit the steam header?
Thread Content
The steam exiting the drum is superheated before entering the steam collection header; however, I have also seen cases where such a header is not used. Please discuss the purpose of installing a steam collection header – is it necessary to have one?
Whether to install a header tank depends on your system; it is considered only when the steam from multiple boilers needs to be combined, or when the steam from a single boiler needs to be supplied to different users

The last edit to this post was made by dongjiang1001 on 2011-6-29 at 14:45. The purpose of using a steam collection header is as follows: 1) To further mix the superheated steam through the header, thereby balancing the pressure differences between various superheater tubes; to reduce thermal disparities among these tubes due to uneven flow rates, and to prevent individual superheater tubes with low flow rates from overheating； 2) Facilitates the installation of important valves such as the main steam valve, safety valve, and vent valve on the steam header ； 3) Facilitates the layout of the main steam pipeline. Therefore, except for small-capacity boilers that are equipped only with a superheater outlet header, larger boilers (with a evaporation capacity of more than 75 t/h) almost all have a superheater steam collection header.
