FUNDAMENTALS
Understanding Net Positive Suction Head Requirements for Pumps 26
Resolving a transient cavitation problem with a centrifugal pump may appear
difficult due to dimensional and thermodynamic factors, but there are ways to
simplify the process. Read about the causes of pump transient cavitation, and
learn about a screening technique for identifying poor designs, along with
corrective measures to solve problems.
OPERATIONS & MAINTENANCE
How to Avoid Full Refractory System Failure in Wood Combustion
26
Refractory material selection is key to addressing the challenging and evolving
environment for facilities that burn wood for power generation. Operators
should work with an experienced refractory expert to help determine the best
combination of refractory products to meet a plant's specific requirements.
Cleaning Boiler Superheaters with a Mobile Shockwave Method
The formation of fouling and clinkers on superheater bundles can diminish
boiler efficiency in thermal power plants. Removing this sedimentation is a
critical maintenance issue, so a cleaning method that helps eliminate downtime
and that can be done remotely is important to overall plant operations.
SMART GRID
Nanogrid Could Hold Key to Clean Energy Future
A nanogrid project operated by the Orlando Utilities Commission in Florida is
providing a testing facility for several power systems, including solar, electric
vehicle-to-grid, flow batteries, and hydrogen, along with a flywheel energy
storage tool.
SAFETY
Flame-Resistant Clothing: Everything You Need to Know
32
Flame-resistant clothing is important for workers in the power generation
industry. Just as important is that workers know how well these garments
will protect them, along with the limits of that protection. And it's critical to
remember that flame resistant does not mean fireproof.
