sizing boiler headers - Boiler and Pressure Vessel

there are 2 interpretations of "header". For the case of a "header type boiler config", the "header' is the common steam transfer pipe from the multiple boilers to the steam user. In that case, the header size is based on limiting the frictional pressure drop and /or noise, vibration and wet steam erosion/corrosion.

The steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit. Steam header Sizing reduces pressure drop and radiation loss. Steam pipes that are undersized cause high pressure drop and result in steam starvation at the point of usage.

Condensate Water Treatment: Because Steam Boiler Pipes Are

By contrast, filming amines are not completely soluble, and therefore, cannot be fed directly into a boiler. In fact, feeding this type of amine into a boiler could cause even worse problems than not treating the condensate at all. In order for a filming amine to work properly, it must be direct injected into the steam header.
