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.
