NO{sub x} emission control for gas turbines: A 1995 update on regulations and technology
- GE Power Systems, Schenectady, NY (United States)
The decade of the 1980`s was one of rapid change for both gas turbine emission control regulations and the technologies used to meet those regulations. The primary pollutant of concern from gas turbines has been, and continues to be, oxides of nitrogen. The Gas Turbine New Source Performance Standards (NSPS), issued in 1979, did not regulate the emissions of carbon monoxide or unburned hydrocarbons from gas turbines because the levels are very low due to the low water or steam injection rates needed to control NO{sub x} to the NSPS levels. However, in December 1987, EPA`s {open_quotes}top-down approach{close_quotes} for determining the Best Available Control Technology (BACT) became a requirement. This ratcheted allowable gas turbine NO{sub x} emission levels down to levels significantly lower than the NSPS. As the allowable NO{sub x} levels decreased, carbon monoxide emissions started to become more of a concern due to the increase in CO levels resulting from massive amounts of steam or water being injected to control NO{sub x} to the lower levels. The Clean Air Act Amendments of 1990 have resulted in the imposition of new emission control requirements not only for NO{sub x}, but also for CO and VOCs in ozone nonattainment areas that has broken new ground for the decade of the 1990`s, as the 1977 Amendments did in the 1980`s.
