Modern methods for addressing deposition, corrosion, and fouling in cogen and CHP plants
By Brad Buecker, Senior Technical Publicist
During much of the last century, many central power stations came on-line to satisfy the rapidly growing need for electricity in the post-WWII United States. Large power stations were a wonder of technology at the time, and I began my career at one of these plants in the early 1980s. However, even as people marveled at these facilities and their intricacies, it came to be recognized that the net thermodynamic efficiencies of these plants were low, with a mid-30 percent range for subcritical drum units, and at most mid-40 percent for even advanced supercritical units.
