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.
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.
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.
Over the past decade, land-based wind turbines have grown from about 700 kW to well over 2 MW.
Coal-fired power plants can have up to 25 coal pulverizer drives, depending on their size.
