Promises of advanced technology realized at Martin
The 2,488-MW Martin station is a gas/oil-fired facility that embodies today`s demand for flexible operations, technological advances, and reduced production costs. Martin station first rose up from the Everglades in the early 1980s, with the construction of two 814-MW oil-fired steam plants, Units 1 and 2. Natural-gas-firing capability was added to the balanced-draft, natural-circulation boilers in 1986, increasing the station`s fuel flexibility. Martin then leaped into the headlines in the early 1990s when it added combined-cycle (CC) Units 3 and 4. With this 860-MW expansion, FP and L boldly became the fleet leader for the advanced, 2350F-class 7FA gas turbines. Further pushing he technology envelope, the CC includes a three-pressure reheat steam system that raises net plant efficiency for Units 3 and 4 to 54%, on a lower-heating-value (LHV) basis. Incorporating the reheat cycle required significant redesign of the gas-turbine/heat-recovery steam generator (HRSG) train, in order to maintain a rapid startup capability without exceeding metallurgical limits. Perhaps even more important than the technological achievements, Martin stands out from the crowd for its people power, which ensured that the promises of advanced technology actually came to fruition. This station`s aggressive, empowered O and M team shows that you can pioneer technology, reduce operating costs, and deliver high availability--all at the same time.
