The 'God Almighty' or 'Mother Nature' had given us an enchanting planet, a planet that had everything in its surface for the humankind to live a happy and peaceful life. Everything that was evil was buried deep beneath the earth so that we are not tempted to see them, touch them or use them.more...

New coal-fired plant construction today costs in the neighborhood of $2 million to $3 million per megawatt (MW). This new facility must then be staffed and operated with new resources and additional fuel consumption. more...

Another inconvenient truth is that we need coal as part of a balanced approach to providing for the nation’s -- and world’s -- electricity supply. This is not merely the desire of energy industry executives, but the reality when one looks logically and practically at the demand for electricity and the means of meeting that demand. more...

Coal represents the United States’ most abundant energy resource. Coal-fired power plants provide 50 percent of our country’s electricity. The U.S. coal resource could satisfy energy demands for the next 200 years. Coal-fired plants provide a more stable cost of electricity than natural gas which has fluctuated by 300 percent in the last few years. Coal-fired power plants are mistakenly perceived as “dirty” and causing environmental harm – especially air pollution. more...

In this first part of this three-part series we explored the corrosion stresses and what we mean when we talk about the “ORP (Oxidation-Reduction Potential) space” – what changes, why does it change, and what does it mean to us. We also examined the current state of the art – the monitoring tools we can use to “see” into a previously opaque process. more...

We all want good control of corrosion and corrosion product transport in power plant condensate and feedwater systems so that they keep running and we all keep our jobs. Most of you who feed reducing agents (also called oxygen scavengers or passivators) already understand that controlling corrosion by measuring reducing agent residuals can be difficult. Those of you who don’t feed reducing agents (all-steel systems, for example) may think that you don’t have to do anything except keep pH within a target range to minimize feedwater corrosion. That’s partly true, but the devil is always in the details. more...

Would you bet your paycheck on the accuracy of your Steam Sample and Analysis Panel (SAP)? That's basically what you're doing every day. Sample panels, essential as the first line of defense in problem detection, are often abandoned in place because they "can’t be maintained." Plant personnel often have low confidence in the analyzers and rely on wet tests alone to monitor and control steam cycle chemistry. Relying on this approach means that problems can be detected only by wet tests. Chemistry or pump problems may go undetected for many hours (the time between tests). Several plants experienced extremely low HRSG pH levels, fosar example. In most of these cases, pH remained low for several hours prior to detection. more...
