Best of the Best 2022: Genelba identifies, corrects combustion-chamber issue using methodology created by plant personnel

V Users / By

The plant’s challenge was to develop a means for monitoring critical equipment to maintain Genelba’s availability and reliability at the facility’s traditional high levels. The solution required creating and implementing a methodology for gathering information from multiple online and offline sources, developing key performance indicators (KPIs), and analyzing them under different boundary conditions as illustrated […]

Frame 6B Best Practice: How BASF Geismar increased the reliability of boiler drum-level controls

Frame 6 / By

Most drum-level control systems employ 3-element logic, with feedback to the controller on drum level, steam outlet flow, and feedwater inlet flow. Data provided by pressure and temperature transmitters are used to enhance the accuracy of the steam-flow value. To illustrate: If the drum-level instrument is a dP-style level transmitter, a pressure transmitter is installed

Generators: A brief history

Generator Users Group / By

By Clyde V Maughan, Maughan Generator Consultants (retired) This historical perspective on turbine-driven generators, in four parts, is based on Clyde Maughan’s recollections from a 72-year career in turbine/generator design, manufacturing, and service—half that time with General Electric Co, the remainder as an independent consultant. Having joined GE in 1950, and having worked closely with

Generator History, Part 1: Electrical insulation systems

Generator Users Group / By

Stator windings Groundwall insulation. Before the turn into the 20th century, insulating materials were natural products: shellac, cotton, paper. The rudimentary stator-winding designs were at low voltage and low temperatures, and apparently functioned fairly well as long as duties were kept sufficiently low. With inevitable trends to larger generators, with higher voltages and higher thermal
