The PGT25 family of gas turbines draws its high efficiency and light weight from GE’s aeroderivative technologies proven in energy applications and aircraft engines, while its ruggedness is inherited from our heavy-duty gas turbine designs. Evolution from the proven GE Oil & Gas models has ensured high reliability and availability for the unique demands of this industry.
The PGT25 is a simple cycle, two shaft gas turbine consisting of an LM2500 aero derivative gas generator coupled with a rugged, industrial power turbine. It leverages the best GE Oil & Gas technology to respond to the demands of a gas turbine in the 23 MW range with high efficiency, reliability and availability, and low environmental impact. PGT25 can operate on a large range of both liquid and gas fuels. It is assembled on a rigid, lightweight base plate with extensive use of standard components, preassembled and tested in the shop to minimize on-site assembly time. Easy maintainability is one of the main features: the gas generator and low pressure turbine (cartridge) can both be easily and quickly removed and replaced, in order to minimize downtime.
The LM2500 has accumulated several million fired hours in both aircraft engine and industrial applications (marine, onshore and offshore gas transmission) as mechanical drive and generator drive. It has a 16-stage axial-flow compressor capable of reaching an 18:1 pressure ratio. Inlet guide vanes and adjustable stator vanes on the first six compressor stages provide for efficient operation over the entire operating range.
The power turbine components are based on GE’s extensive experience with heavy-duty gas turbines and axial/centrifugal compressors. Aerodynamic blading obtains very high efficiency at both design and reduced speeds. The 6,500 RPM design speed means the turbine can have two stages with a moderate aerodynamic load and a high expansion efficiency. The two expansion stages have a high-energy, three-dimensional design.
Delivering high efficiency across a broad operating range in high-volume, low-pressure downstream applications.
GE axial compressors are based on decades of experience from Nuovo Pignone, Allis Chalmers, Conmec, and GE. This compressor is best suited to applications with very high flow rates with typical polytropic efficiency exceeding 90%. The variable stator vane design is a key feature of our AN axial compressor. It enables a broad operating flow range and turndown to meet variable process air requirements with a fixed speed motor driver. The number of blade rows can be tailored to fit process needs with typical compression ratio ranging from 3 to 7. The inner stator blade carrier is housed in an external, fabricated, horizontally split casing.
The airfoil design, including rotor and stator blades, is standardized for all frame sizes. This robust design delivers optimum aerodynamic and mechanical behavior. Radial and thrust bearings are of the tilting-pad type similar to our centrifugal compressor designs. Process connections can be either radial or axial inlet to meet plant layout needs.
Our engineering expertise and extensive product portfolio allow us to leverage our compressor drivers, air filtration solutions, compressor train and auxiliary designs to provide high efficiency compressed air solutions for any application.Read More
A portfolio of products well-known for their fuel flexibility, maintenance ease, high reliability and availability in a wide range of mechanical drive and power generation applications.
This single-shaft turbine is a compact, heavy-duty prime mover designed for long life and ease of operation and maintenance. The three main features of its simple design are a 17-stage, axial compressor; combustion system with 10 chambers capable of burning a wide range of fuels (DLN also available); and a two-stage turbine with high-energy stage design (the first-stage nozzles are cooled by the axial compressor discharge air).
The MS5001PA is the ideal solution for power generation where low maintenance, reliability and fuel economy are required. Low operating and investment costs make the MS5001PA packaged power plant an economically attractive system for load generation. The turbine is also ideally suited for cogeneration, achieving a very high fuel utilization index and considerable fuel savings. Typical applications include industrial plants for cogeneration of power and process steam or district heating systems.
MS5002 C & D
The MS5002 was introduced in the 1970s and has been updated and up-rated over the years to meet the industry’s increasing output requirements. The fleet continues to demonstrate ease of operation and very high reliability and availability. It is a two-shaft, heavy-duty gas turbine designed for high operating efficiency over a wide range of speed and load conditions. This turbine is designed for mechanical drive applications such as gas boosting, gas injection/re-injection, pipelines, LNG plants and gas storage. It has a broad operating speed range to meet the requirements of the most common driven equipment (centrifugal compressors and pumps) as well as the ability to burn a large variety of gas and liquid fuels.
With simple and robust designs, complete maintenance can be performed on site without the need for specialized tooling or service shop assistance. The high-pressure shaft has a 16-stage (17 for MS5002D), axial-flow compressor and a single-stage, high-energy turbine. First-stage nozzles are air cooled and second-stage nozzles are variable angle type. The low-pressure shaft is a single-stage, high-energy turbine. Twelve combustion chambers are contained within a single wrapper, a wide range of gaseous and liquid fuels can be burned, and a DLN combustion system is also available. A centralized lube oil system supplies clean, cooled, pressurized oil to lubricate the gas turbine and the driven equipment including the oil required for any compressor seals.
This dual-shaft turbine has proven capabilities in power generation and mechanical drive applications, delivering high efficiency, low environmental impact and high reliability. It uses our state-of-the-art DLN2.5H combustion technology with over 14 million firing hours in GE’s F/FA frame gas turbine class, but with firing temperature about 100°C lower to maximize hot parts life. Superior efficiency is achieved through optimized airfoils for both axial compressor and turbine sections, clearances, leakages and the distribution of cooling flows. The MS5002E has the lowest environmental impact in its class: its NOx level is 15 ppm and it reduces CO2 emissions by more than 20,000 tons per year, compared to the MS5002 C and D or MS5001.Read More
