A mobile 44MW unit designated SGT-A45 TR has been added to the Siemens gas turbine portfolio to address the growing market for rapid power. This aeroderivative is packaged for rapid deployment and can be installed in less than two weeks, according to its maker. Its design features what Siemens says is outstanding power density, high fuel efficiency and excellent operational flexibility. This, and the standardisation and modular design of the package, makes it particularly beneficial for customers with urgent power needs, or for regions with less developed infrastructures.
It also provides significantly more electrical output than comparable models currently on the market. Its design is based on existing Siemens products and the aero-engine technology it inherited from Rolls-Royce.
The gas turbine core utilises components from the Siemens Industrial Trent 60 that have been adapted to mate with a proven free power turbine, a design that exploits the experience gained from millions of operating hours accumulated in airorne, industrial and marine service.
Each unit is fully assembled and tested at the factory in order to minimise the scope of commissioning work needed at site. Transport of the turbine is made easier by its compact design and relatively low weight. When required, the unit can be carried as air cargo. It can run on gas or liquid fuels, and transition smoothly between both fuel types while in operation. It can reach full power in less than 9 minutes from start without need for auxiliary systems to maintain the unit in an operationally ready standby mode. In the event of a shutdown, the unit can be restarted at any time to restore power quickly, as it has no ‘hot lockout’ restrictions.
