Pressure difference is used as the driving force to transfer steam from the boilers into the header, or from header to header, and from the header to downstream equipment. The flow calculations between the boilers and the header ensure a balanced transfer so that the header pressure does not exceed the feeding boilers.

Steam flows through the saturated steam line to the superheater inlet header. It makes four passes through the superheater increasing steam temperature 300-400 F to approximately 850 F and then exits through the outlet header. Superheated steam leaves the outlet header and a portion is routed to the desuperheater inlet based upon system demand.

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.

All headers are tested at 125psig. Achieving the proper results with Primary Secondary Piping requires knowledge of the application objectives, limitations imposed by other equipment in the building, limitations of the boiler room, and knowledge of applicable building and boiler room codes.
Steam Systems 6 2. Obtain a composition analysis for each fuel, which will be necessary for calculating fuel usage for a given load. 3. Determine the fuel costs; this is necessary for the economical optimization of boiler room design. For new boiler(s) installation
They are a very good thing for a steam boiler, especially if the existing supply/feed is close to the recommended height above the water line in the boiler. Your supplies off the top of the boiler can go up much higher to the ceiling and back down to the header which has the equalizer and feed the system off the header. Keeps the steam drier.
Headers form an important part of all types of boilers. Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them.
