Overfiring during startup General Electric Speedtronic™ Mark I control systems were installed on gas turbines in the early 1970s, primarily on MS5001N and MS7001B engines. Fig 1 shows a typical Mark I panel being tested using a device known as the Speedtronic Calibrator. Note that the Calibrator has two ribbon connectors patched into designated locations

Air inlet systems—including filter houses, evaporative coolers, cooling-coil support structure, silencers, ductwork, etc—seldom get the respect they deserve. Properly maintained, they help assure maximum output and high availability of your gas turbines. Yet, they are almost an afterthought at many plants, the focus being primarily on rotating equipment. Annual inspection of the air inlet system

Many combined cycle (CC) turbines working in more and more aggressive operating regimes face the added challenge of shrinking O&M budgets. From an accountant’s view, fewer operating hours for older machines equates to less need for O&M funds, however wrong-headed that may be from the deck-plates view. Thus, the hunt for less expensive but reliable,

In what GE claims to be the largest gas turbine black-started by a modern battery, Entergy Louisiana has added a 7.4 MWh lithium-ion (nickel-magnesium-cobalt chemistry) unit at its Perryville power station to restart a 2001-vintage, 150-MW 7F.03 peaking gas turbine/generator should grid power be lost. To re-energize the grid, black starts typically require separate gas
