Eight Bells: Charlie Zirkelback, 77
News of Charlie Zirkelback’s passing on July 8, 2016 reached us only recently. The Pascagoula (Miss) native, a graduate of Mississippi State University (1965, mechanical engineering), died at his home in Port Lavaca, Tex, after a long battle with Parkinson’s disease.
Charlie Zee was a “character.” He both taught and entertained at Frame 6 User Group meetings where Charlie may have been best known professionally outside Union Carbide/Dow Chemical. He worked at UC/DC for 39 years and was recognized by the chemical giant with the title of Corporate Fellow for his valuable contributions. Charlie was a “plant guy,” traveling to company facilities worldwide as a trouble-shooter and problem-solver. He experienced most everything having to do with power and process operations and maintenance in his career.
Charlie believed there was nothing he couldn’t fix or make work better. CZ put industry icon Marmaduke Surface blow to shame, Rube Goldberg as well, with his creative solutions. And once he got control of the mic at Frame 6 meetings it would be non-stop Charlie until the next scheduled break or meal. Loved and respected by colleagues, he was honored with the Frame 6 User Group’s 2006 John F D Peterson Award for his contributions to the industry and the user organization.

Inspection guide for drum-level instrumentation
The 2017 edition of “Boiler Inspection Guidelines for Drum Level Instrumentation,” issued by Clark-Reliance Corp, concisely presents inspection requirements for ease of reference by O&M personnel. The basis for the seemingly indestructible, spiral-bound 5.5 × 8 in. book is Section I of the ASME Boiler & Pressure Vessel Code (current edition). It includes requirements for water columns, water gage valves, gage glass, remote level indicators, magnetic water-level gages (MLGs), and water-column isolation shutoff valves.
New to the guidebook this year is content pertaining to the use of MLGs, a topic which may have generated confusion among plant personnel in the past. The standard use of MLGs available from most manufacturers could result in a Code violation and safety hazard. Code compliance is assured by following guidelines presented in the Clark-Reliance publication.
The information presented is completely up-to-date and incorporates the 2015 Code changes and CSD-1 requirements, as well as recommendations from Section 7. Additionally, it identifies the most common non-compliant drum-level equipment arrangements and recommended solutions. The book is free to qualified recipients; visit www.boilerinspectionguide.com.
Duct balloon protects gas turbine during layup
This is not news to industry veterans, but newcomers might benefit from a review of this best practice for gas-turbine protection during layup. A major international company in the oil and gas industry was dealing with materials wastage and other issues in a gas turbine located at a refinery near the seacoast and subjected to long-term layups.
The existing inlet damper was ineffective and a duct balloon was installed to stop the ingress of moisture-laden air and sea salts. A dehumidification system was added to increase the level of protection and together they are doing the job intended. Installation of the balloon takes only minutes and removal is quick and easy (photos). Dekomte (UK) Ltd subsidiary, Intech, handled system installation for US supplier G R Werth & Associates Inc.
Emerson makes the virtual powerplant a reality
With the introduction of what Emerson says is the industry’s first integrated control and simulation platform, the company has positioned plant owners to fundamentally change how they operate their facilities. Emerson reports that sales of Ovation™ high-fidelity embedded simulation have more than doubled in the past year, confirming significant interest in the “virtual powerplant” and its value in minimizing operational risk and in improving reliability.
In the virtual plant, the Ovation simulator runs in parallel with the Ovation control system. This allows operators to test control logic changes in advance, based on real-time plant data, ensuring those changes won’t disrupt operations. Other Emerson technologies—such as pattern recognition, Pervasive Sensing ™, and analytical tools—enhance the virtual experience.
Finding experienced operators for today’s advanced plants is one of the industry’s biggest challenges and an opportunity for Emerson given its controls advancements. Bob Yeager, president Power & Water, Emerson Automation Solutions, told the editors, “Emerson is improving operator effectiveness and confidence while reducing operating risks through intelligent control systems, more realistic training and simulation platforms, and easier-to-use technologies.”
