Abstract

As the power market becomes more competitive in supplying reliable and cost-effective power to various industries, it has become imperative that the power plant is designed and operated to run reliably and efficiently. The majority of the power generated is through a steam turbine where it extracts the energy in the superheated steam. This steam is generated from a boiler or heat recovery steam generator (HRSG), where the heat is generated from a combustion turbine or fossil-fuel fired boilers. This article will focus on the steam-cycle water chemistry of a 525.9 megawatt (MW) combined-cycle power plant without duct firing, and will discuss and review causes, consequences, and potential solutions to prevent the detrimental impacts of water chemistry, which include pitting, corrosion, and scaling. Deaeration, dissolved oxygen, hydrazine and scaling are also discussed.
