STEJASA has successfully delivered an EP contract in Santa Fe (Argentina). This fast-track project was engineered, fabricated and delivered in under 6 months. The diverter damper, guillotine, stack and steel structure have completed their assembly downstream an SGT5-2000E Siemens turbine. Today commissioning is ongoing with our field service team, who was also present during the complete construction phase.

STEJASA has successfully delivered 6 “single piece” diverter dampers and guillotines. The diverter dampers will be installed in a “OC to CC” conversion in the Middle East. Due to the plant’s location near the harbour, these 55 tons each diverter dampers will be shipped in a single piece. This will allow a shorter and more efficient construction phase at site. The hydraulically operated diverter dampers will be working downstream six 185MW Ansaldo V94.2 gas turbines.

STEJASA has concluded the fabrication of four diverter dampers and four guillotines to be installed downstream four SIEMENS SGT-800. The diverter dampers free flow area is 3.050 x 3.050mm with a design temperature of 650ºC. Of course these diverter dampers will be 100% tight thanks to the seal air chamber and 2 x 100% API 673 seal air fans. All the equipment (instrumentation, pneumatic actuator, etc…) has been designed for a zone 2 classified area. The use of a pneumatic actuator and I/P positioner to operate the diverter dampers, will allow a full heat transfer control to the HRSG.
