Perfect for many fuelsAbout three-quarters of the gas turbines in operation today are fired with natural gas, with fuel oil typically used as a backup fuel. The remaining one-quarter use alternative fuels such as residual oils from petroleum dis-tillation, low-caloric gases from natural gas liquefaction, or synthesis gases.
Arguments in favor of using alternative fuels include the benefit of utilizing locally available resources. This sources contain e.g. low calorific gases or gases containing CO2, H2S, and N2, as well as cruide oil and other liquid fuels with high viscosity. The SGT-2000E series gas turbines are also perfectly suited for burning these fuels.
The SGT-2000E series does not require cooling air holes in the blades. This means that it can also process ash- producing fuels like heavy fuel oils that would otherwise block the holes. The upstream external combustion chambers are maintenance-friendly and contribute to the high reliability of the hot gas components. A variety of burners are available depending on the composition of the fuel.
Optimal performance and availabilityThese are the essentials for competing successfully on the electricity markets: robust and flexible performance at a low price, with high availability and ease of mainte-nance, and technical properties that are optimally matched to the task at hand.
In short, what counts is the right turbine – with the perfectly matched modules of the SGT-PAC 2000E series package. The SGT-2000E series is regarded as the workhorse among the Siemens gas turbines. In addition to their high flexibility with respect to fuels and power output, the SGT-2000E series provides outstandingly low NOx and CO2 emission values, even in the part-load range.

Benchmark service flexibility: a variety of maintenance concepts to choose from
Less maintenance effort, fast repair As early as the design phase, Siemens stands out for the service friendliness of its gas turbines. The scope of maintenance work and the resulting outage times are established during the gas turbines' development.
Thanks to its robust construction, the SGT-2000E series is exceptionally reliable – and service-friendly by design. This begins with the ease of accessibility of all important components. For example, the two separate silo combus-tion chambers are readily accessible for service purposes, making it easy to inspect the hot gas path. Inspection and cleaning of the turbine blades can be easily performed thanks to easy accessibility. Another important benefit is the Siemens rotor design, it enables the de-stacking of the rotor on-site at the power plant ensures that no rotor transport is necessary during major outages.
What do you want to achieve?This is precisely the question that determines how you operate the flexible SGT-2000E series gas turbine. Its operating parameters in turn determine the thermal loading of the components – and hence the length of the mainte-nance intervals. If you want to maximize availability of the electricity supply for your customers, or need the turbine
to drive your equipment in the oil or gas business, you need a totally different maintenance concept than you would for operating a turbine for maximum energy efficiency.
We can provide you with an appropriate maintenance concept designed for your plant operation. For typical oil and gas applications, for example, there is the 41 MAC concept, with 41,000 equivalent operating hours (EOH) between two major inspections and with intermediate maintenance every 8,000 EOH. This keeps maintenance times down, with the direct benefit of higher availability – a different approach from applications where there is greater emphasis on energy efficiency. To meet the higher requirements of thermal stressing of the components and to deliver optimal performance at all times, the interval between two major inspections is reduced to 25,000 EOH – the 25 MAC concept. We continually work to optimize our turbine maintenance concepts, and we ensure as early as the design phase that future adaptations can be applied to today’s machines.
