In July 2016, a coal silo collapsed at an Indiana power plant. The root cause was identified as cracking of the cone-to-skirt weld. Warnings to inspect this vulnerable weld were published widely in conference proceedings and trade journal articles. Nevertheless, coal silos continue to fail at an alarming rate (Figure 1), which suggests that the […]
A Florida pulp and paper mill faced a complicated, dangerous process to clean its power boiler during scheduled outages.
Previous efforts to clean the boiler included manual water blasting from scaffolding, which posed a safety risk to workers below due to the potential for falling debris.
The Operations team at MPW Industrial Services recommended that the facility’s

The Tennessee Valley Authority’s third coal plant conversion to gas combined cycle generation, at the venerable Allen plant near Memphis, Tennessee, created the most-efficient combined cycle plant in its
Innovative welding techniques can produce consistently better-quality joints. Special alloys, appropriate pre- and post-weld heat treatment, and proper weld procedures can all help prevent catastrophic failure
Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what affects
Corrosion products can form quickly in power plant systems if water, air, and metal are allowed to occupy the same space. Localized corrosion can take any of several distinct forms, such as stress corrosion
Understanding the properties of bulk materials and how they interact with environmental factors is vital to safe operations, but having an honest conversation about the hazards, so risks can be properly
Silicon Valley Power implemented a system using machine-learning technology to monitor critical power plant components. The solution has proven to reduce downtime and save money. Furthermore, its wireless
