Dipak K. Sarkar, in Thermal Power Plant, 2017. 9.2 Objective. In large steam generators there are about tens of thousand tons of steel tubes, pipes, drums, or steam separators, other vessels that contain the high pressure steam as is evident from the earlier discussion.To build an integrated vessel, the steam generator, utilizing the above items, more than 60,000 welding joints need to be ...

Before 2000, only cyclone separators (see schematic in Figure 17) allowed collection of the modifier⧸solute without exposing the operator to aerosols. Cyclones are one form of a gas–liquid or momentum separator. Cyclone separators operate at 20–60 bar.
