Demin water replaces glycol solution in closed cooling system, improves heat transfer

Miguel Perez Ghisays, general manager of the privately held Termocandelaria peaking facility near Cartagena, Colombia, and his talented staff, embrace a process of continual improvement in all facets of operation and maintenance. Readers may recall the plant’s success in converting its two W501FC engines from gas-only to dual fuel in only 11 months after contract

Increase intervals between gas-turbine fuel-valve overhauls with water cooling

Reliable operation of dual-fuel gas turbines on oil demands that owner/operators protect against coking of distillate in fuel-system components. Active cooling is one solution available to users for assuring both reliable starts on liquid fuel and reliable fuel transfers from gas to oil. Recall that stagnant fuel in supply lines not protected against heat radiated

Advanced manufacturing center enables Conval to better serve HRSG users 

HP superheater and reheater drain-system designs and operating practices that do not remove all condensate prior to initiation of steam flow during cold, warm, and hot startups are unable to protect tube-to-header connections, header bores, and nozzle-to-header connections from severe thermal fatigue damage. Such damage has resulted in many premature tube failures and can be

European meeting validates topics under consideration for upcoming HRSG Forum

The fifth annual meeting of the European HRSG Forum (EHF2018), held May 15-18, in Bilbao, Spain, attracted 72 participants from 16 countries. Dr Barry Dooley of Structural Integrity Associates Inc, who chaired the meeting as he had done previously, considered the event “highly successful.” EHF is supported by the International Assn for the Properties of

Inspect, maintain hoses to prevent failures, protect personnel

Special to CCJ ONSite by Brian Hulse, BDHulse Consulting Services LLC If we know one thing about hoses, it’s that they’re expensive. So we always try to extract maximum value from them before they’re replaced. The hoses used on most gas turbines are manufactured with no published shelf-life or working-life limitation. Each hose on the

Clean inlet air at the proper temperature promotes top performance

Building the better mouse trap Special to CCJ ONsite by Brian Hulse, BDHulse Consulting Services LLC It’s an age-old quest—building the better mouse trap. The US Patent Office has issued over 4400 patents for mouse traps although, paradoxically, only about 20 of them have ever seen any commercial success. This would lead one to think
