GPA-C-6.3 gas turbine pumping unit
The GPA-C-6.3 gas turbine pumping unit retrofit is conducted by substituting the NK-12SТ engine for the GTU-10PC gas turbine, and by including an appropriate hardware for upgrading the gas pumping set systems. For today, the preliminary engineering of the retrofit has been executed.
Part number:
Supplier:
Description
The differences of GTU-10PC gas turbine from the GTU-10P base design (for GPA-C-6.3 retrofit) are determined by particular conditions of tie-in and location of components in the upgraded gas turbine pumping unit.
During retrofit the hardware from GTU-10PC is installed on the existing foundation into an existing enclosure with upgrading of gas pumping set systems.
The hardware provides for upgrading of gas compressor systems for the GTU-10PC installation, and also, replacement or upgrading of out-of-date or worn-out systems, and it is determined by the specification approved by the Customer.
Automatic control unit (ACU) is based on МSКU-SS 4510-10-38, and is common for gas turbine pumping sets and other gas turbine mechanical drive systems.
Primary Performance Data
ISO Conditions, loss-free, fuel: Methane (LHV=11958 kCal/kg)
Power turbine shaft output, MW 10.3
Efficiency at power turbine shaft, % 33.1
Exhaust gas temperature, °С 454
Output speed, rev/min 9000
Exhaust gas flow, kg /s 42.9
Service life:
-overhaul life, hr 25 000
-design life, hr 100 000
Advantages
The retrofit of GPA-C-6.3 gas turbine pumping unit with application of GTU-10PC gas turbine and new hardware allows to improve the performance, that is:
to improve reliability of the driven engine systems;
to improve reliability of the modified systems;
to reduce the consumption of fuel gas;
to reduce irretrievable losses of lube oil;
to improve the ecological characteristics.
The retrofit is carried out with maximum use of existing systems of the unit.
