SGT-600 (PC)
Power Concept for SGT-600 Gas Turbine
What it offers
The SGT-600 (PC) or Power Concept is an upgrade of SGT-600 to increase engine performance parameters which makes it possible to increase power output by more than 2 MW. In this design the efficiency can be expected to increase by 1%. In addition, lifetime is extended, all due to a new state of the art 3D design of compressor and reduction in turbine cooling mass flow rates by new materials choice in addition to an optimized design of the cooling and sealing systems. SGT-600 (PC) gas turbines are suitable choices to be coupled with re-bundled gas compressors in order to increase the capacity of gas transportation lines, due to their increased power and efficiency and low added cost to improve performance.
By implementing this upgrade in Pataveh, Dorahun, Dehagh, and Ghom stations, the capacity of IGATIII gas transportation line will increase up to 10%. Total profit due to this upgrade is comparable to the cost of a number of new GT units per year. The upgrade is designed to be implemented in level B or C maintenance plan with an expectation of 10 to 15 days increase in SGT-600 scheduled inspection plan.

A glimpse into the new design
These modifications can be installed on the gas turbine by investing extra cost for upgraded parts in the maintenance intervals. The main concepts to improve performance are using advanced aerodynamic design in compressor and reducing required cooling and sealing flows in turbine component. Performance improving procedures are executed in compressor and turbine components.
Compressor
· New design of IGV, first and second stages of the compressor
· New design of stators in third to tenth stages of the compressor
These changes result in a 2.5% increase in the compressor mass flow rate and a 0.9 % increase in the compressor efficiency.
Compressor Turbine
· Turbine materials improvement by using materials casted by directional solidification method
· An optimized design of the cooling and sealing system
These changes in compressor turbine result in a decrease in cooling and sealing system mass flow rate.
