Test Your Knowledge: Steam Turbine Rotor Vibration

Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of steam turbine blades and other internal components is one of the most serious problems experienced in power plants. The problems often reduce plant availability by limiting generation […]

MPW’s Improvements Lead to Savings for Southeastern Pulp and Paper Facility

Problem
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.
Solution
The Operations team at MPW Industrial Services recommended that the facility’s

Test Your Knowledge: Boiler Chemical Cleaning

Most engineers and operators know (or should know) that boiler tubes containing deposits create long-term reliability problems for the boiler. Long-term overheating of the metal will result from prolonged operation with heavy tube deposits. The tubes will first bulge and then fail. Because the deposits tend to be widespread, this generally means that large sections of […]

How to Automate Workforce Scheduling

If you’re a power plant supervisor, you’ve undoubtedly been forced to find a worker during off-hours on the spur of the moment. New tools are being used today that allow automating the callout process—and workforce schedule. Last summer City Utilities (CU) of Springfield, Missouri, joined a list of power companies automating workforce scheduling and callout […]
