Technology advances for heat recovery steam generators (HRSGs) at power plants continue to provide higher efficiency, with major gains recognized in natural gas–fired and cogeneration systems in recent

Every month, POWER magazine publishes several articles in its Global Monitor section covering topics important to the electric power generation industry. The articles typically feature interesting updates on progress made at notable projects around the world, big policy changes, or promising research and development (R&D) news. Short notes about major contracts are also touched on […]

It’s always difficult to select winners from the field of nominations submitted to POWER for its annual awards, and this year was no exception. The Wudongde Hydropower Station was the big winner, while

In the power plant, long-term efficient generation depends on minimizing corrosion and deposition within the steam/water cycle. Therefore, sodium in the power cycle must be maintained at deficient levels to shield turbines from corrosion and scaling. Water treatment performance and purity determination have depended on sodium measurement for nearly four decades. It is crucial for […]

Reduce risk by empowering your workforce by deploying simplified and intuitive cyber security tools designed for industrial systems and users.

How to Prioritize Safety over Compliance for Long-term Success

Mechanical Dynamics & Analysis (MD&A) performed a complete reheat stop valves restoration along with one LP stop valve. These RH stop valves on a Siemens Westinghouse® unit had not been fully restored for 14 years. Pre-outage planning took place between our team and key plant personnel.  Upgraded valve materials were designed and manufactured, and new clearances […]

Lubricants have been around for thousands of years, serving a multitude of purposes. The technology has come a long way since olive oil was used to move stones and other heavy objects as far back as the 17th century B.C., according to archaeological discoveries. Petroleum-based products helped usher in the industrial age, and advancements in […]

This paper explains the mechanisms that affect lubricating oil consumption in stationary gas engines. It explains the positive and negative consequences of oil consumption. It discusses the importance of

Pressure relief valves (PRVs) are a critical line of defense for pressure vessel protection in the power industry. Generating facilities worldwide depend upon these devices to sense and quickly relieve
