Rotor Air Coolers
Rotor
air coolers are used in the power generation industry and are designed to
cool hot air and generate steam. The hot air is the by product created when
air is used to cool the fuel gas turbine. The hot air, after running through
the turbine, is then cooled to the proper temperature and returned to the
turbine. The heat in the air stream is removed and used to make generate steam
in the "Rotor 
Air
Cooler"
Hot air passes through the tube side while steam is generated on the shell side. The air may be cooled utilizing either just a LP (low pressure) steam generator or a two step process with both a IP (intermediate pressure) and LP steam generator. When two exchangers in series are utilized, the exchangers can either be completely separate and piped in the field by the customer, or bolted together to minimize piping and pressure drop. The shell side is carbon steel, tubes are generally SS304, and the tube side is either SS304 or chrome molly. As with all Bos-Hatten units, these units are built to the ASME Code, Section VIII Div 1. A UB stamp is generally provided.
