Heat Recovery Steam Generator
- Combined Cycle Power Plant (CCPP) is an eco-friendly and high-efficiency power plant that uses LNG as its main fuel. It produces primary electricity through a gas turbine, and the high-temperature exhaust gas of the gas turbine is used to generate steam through an Heat Recovery Steam Generator (HRSG), which then produces secondary electricity through a steam turbine. The HRSG, one of the main equipment of CCPP, is a comprehensive facility that requires technology in all areas, including the quality of the high-frequency finned tube that generates steam, the overall engineering capability of the HRSG, and the management of the pressure and non-pressure part manufacturing process.
- SNT Energy possesses the original technology for HRSG engineering and own production capabilities for the pressure & non-pressure parts, including the production of high-frequency finned tubes. This enables us to meet customer’s delivery schedule and quality requirement with excellence. Additionally, SNT Energy has the proven engineering records for O&C Section and Super-Module Type HRSG, and also capability for cutting edge technology including TCA of MPW and I-RAC of Siemens / Hydrogen-Co firing operation / integrated design considering diverter damper, supplement firing and Air Pollution Control System.
- SNT Energy has an annual manufacturing capacity of 12 HRSG units for H-Class gas turbine in both SNT’s domestic and international factory.
