Siemens announced it has upgraded its SGT-800 industrial gas turbine to a power output of 57 MW, up from the current 47.5 MW rating. Both the upgraded version and the current rating will be offered to the market.
The gas turbine has an electrical efficiency of more than 40% in simple cycle application, while in combined cycle configuration the power output is 163 MW at a net efficiency of more than 58.5%, Siemens said.
“The most powerful SGT-800 to date is aimed primarily at industrial power producers and oil and gas companies that have a particularly high energy demand,” said Nick Muntz, CEO of the Siemens Distributed Generation Business Unit. “We’re thus helping meet the rising global demand for distributed power generation and offering a high-end product for such applications.”
The improved performance of the 57 MW rating has been achieved through improved gearbox and outlet casing/diffuser efficiencies, Siemens said. The gas turbine’s footprint has been reduced thanks to a shorter design, and a higher degree of pre-assembly has been introduced for shorter installation time at site.
Siemens said the 57 MW upgrade follows the design philosophy of taking small, evolutionary fine tuning steps while staying close to the commercially proven and reliable design of the SGT-800 industrial gas turbine. Only improvements of gas turbine parts using Siemens existing and mature core engine technologies have been made.
To date, more than 325 SGT-800 turbines have been sold worldwide. The Asia Pacific region is an especially important market for the machine, with more than 100 units sold, 71 of them in Thailand alone. The installed SGT-800 fleet has currently reached more than five million operating hours, the company said.
