Don't Let Startup Emissions Slow You Down
In a Power Enginerring article, the authors point out that new combustion turbine (CT) simple and combined-cycle plants face new challenges in permitting because of more stringent startup emission limits. Recent permits issued in a variety of jurisdictions have included limits on startup emissions, both in mass per start and rolling annual startup mass limits for VOC, NOx and CO. The increased use of heavy duty/frame CTs for peaking applications create additional challenges. Startup and shutdown durations and emissions rates vary widely depending on CT model and other plant equipment and design choices.

The reducing environment produced by oxygen scavengers initiates and propagates flow-accelerated corrosion (FAC) in the feedwater system and other components of high-pressure steam generators, including heat recovery steam generators (HRSGs). Since 1986, FAC-induced attack has caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for many new power plants both domestically and globally, and in which the condensate/feedwater system contains no copper alloys, continue to call for oxygen scavenger feed to the condensate. This document is a response to this misguided trend.

Questions answered regarding HRSG water/steam chemistry and prevention of corrosion and fouling in steam generators. Even seemingly minor issues have been known to cause failures that cost power producers millions of dollars and in some cases even claimed lives. This is the ultimate cost.

Power Plant Chemicals Webinar - Hot Topic Hour September 25, 2014
The level of knowledge demonstrated by the speakers relative to the challenges of preventing corrosion and malfunction of gas turbine combined cycle plants which are cycling hundreds of times per year and may be using poor quality source water makes a persuasive case for continuing expert advice.
