Course Description

In high-pressure boilers, the term “high pressure” normally refers to the range of 900 psig (63 kg/cm2) to well above the supercritical pressure 3508 psig ( 247 kg/cm2). Steam temperatures for many of these boilers are often at least 1,000o F, with some modern units operating at 1,050 to 1,100oF.  Conditions inside these units are very demanding, generally requiring high-purity makeup water, with precise chemical treatment and monitoring to minimize corrosion and deposit formation. The 1990s brought the emergence of combined-cycle power generation, in which combustion turbine exhaust gases provide the energy for steam production in heat recovery steam generators (HRSGs). Most common are triple-pressure HRSGs, with a high-, medium-, and low-pressure boiler (evaporator).  Such configurations add complexity to chemistry control.  Many power plants today are no longer base-loaded, but rather cycle up and down in load, or on and off which imposes a greater degree of complexity to the cycle chemistry control.  Cycling has a profound impact on both operational and off-line chemistry, and on corrosion protection.  Impurity ingress from a condenser tube leak or other source can cause immense problems if not corrected quickly.  The use of reducing agents (“oxygen scavengers”) in condensate/feedwater loops is now considered not to be a best practice.  And even minor carryover of impurities with the steam can cause major problems in the turbines of power plants.

This comprehensive course reviews the entire water-steam cycle, including the various forms of waterside degradation and corrosion that may occur in the feedwater/condensate, boiler/HRSG, and steam circuits. The various chemical water treatment programs for feedwater, boiler and steam are presented in detail.  Also covered are the monitoring and troubleshooting aspects of modern high-pressure boiler plant chemistry as well as the most common configurations of boiler feedwater preparation plant. This course encompasses best practice concepts throughout.

This course is very practically oriented and focused on best practices.  Lots of invaluable insights are shared. The instructor has 30+ years of experience in high-pressure steam plant systems.
