Supercritical Plants to Come Online in 2009

摘要

Pulverized coal combustion comes in two flavors: subcritical and supercritical. Supercritical units operate at higher temperatures and pressures than subcritical units. Higher pressures increase turbine efficiency and power output so less coal is used to produce the same amount of electricity.rnSupercritical steam cycle technology has been around for decades. The first large power units with supercritical main steam pressure were built in the U.S. in the early 1960s.
