Hydrogen Production By Steam Reforming - Chemical Engineering
May 01, 2010 · Transfer-line steam generator. The outlet transfer line from the reformer is used to generate high-pressure (usually 650 psig) steam. The reformer effluent gas exits through the transfer line at about 1,400 o F and enters the tube side of a single-pass steam generator. BFW is fed through the shell side and becomes 650 psig steam.

Boiler (power generation) - Wikipedia
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
