Nonetheless, its implications are significant, both in terms of repair and outage costs as well as the potential for cracking in components that may be extremely difficult to repair. These concerns led to the formation of the International Cooperative...

... of tight condensers. The drum-type boiler can handle contaminants more readily because nonvolatile solutes remain in the water for periodic removal by blowdown. Boilers also may be classified by their operating pressures relative to the critical steam pressure of 22.12 MPa (3208 psi). Thus, subcritical...
