High boiler efficiency is vital to power generators trying to trim costs and improve performance with efficient and effective fuel use.
Predictive maintenance (PdM) involves monitoring equipment over time for conditions that indicate impending failure, determining whether corrective action is required and, if necessary, taking action before equipment failure.
When management at Newfoundland & Labrador Hydro’s Holyrood Thermal Generating Station learned that support for its legacy distributed control system (DCS) would end in 2005, they began planning a DCS upgrade almost immediately.
Shielded with protective visors, operators at Westar Energy’s three 800 MW generating units at St. Marys, Kan., attempted to inspect the plant’s boiler tubes for signs of slag by looking through the boilers’ hot flames.
Developers of a non-refrigeration technology that can enhance the performance of small combustion turbines - effectively creating greater output a cost below adding additional capacity - contend it will work with much larger turbines, too.
For many years, heat treating critical welds made with alloy steels that have gained wide acceptance in the power industry has been a tedious and exacting procedure.
American Electric Power Co.’s (AEP’s) Gen. James M. Gavin Plant in Cheshire, Ohio, contains two 1,300-MW units built in the 1970s.
It’s been happening in consumer markets for years: Companies have been increasing their efficiency by putting more capability into consumers’ hands.
