Pratt & Whitney Power Systems - Advanced Aeroderivative Gas Turbines

Pratt & Whitney Power Systems (PWPS), the industrial gas turbine division of Pratt & Whitney, has taken the advanced technology of P&W proven aircraft engines and applied it to an extensive product line of land based gas turbines. Whether it is for electric power generation or for applications requiring variable speed mechanical drive such as marine propulsion, gas compression or liquid pumping, the 450kW to 60MW gas turbine product portfolio offers competitive, efficient, flexible products.

LAND BASED GAS TURBINES

Since the sale of its first gas turbine for pumping natural gas in October 1960, PWPS has sold gas turbines for a variety of applications. These include electrical power generation, offshore platform power, oil and gas transmission, industrial drives, locomotives and marine propulsion. Combined, these turbines have accumulated hundreds of millions of heavy-duty industrial service hours.

FT8® INDUSTRIAL GAS TURBINE

In 1986, PWPS began a program to design, develop, and manufacture a technologically advanced, highly efficient industrial gas turbine, the FT8. This gas turbine incorporated many technological features of the Pratt & Whitney JT8D series aircraft engine. The JT8D is one of the most successful jet engines in commercial aviation history, with over 14,000 sold and a total of more than 400 million hours of reliable operation. Today, approximately 200 FT8 gas turbines are currently installed or on order with units in operation on five continents.

The FT8 is compact, easy to install and is capable of using a variety of fuels. The gas generator can be changed in less than eight hours due to the modular design of the engine. Similarly, it can be disassembled into its main modules and reassembled in less than four days.

The latest improvement to the FT8 offering is the streamlined SWIFTPAC™ configuration of 25MW and 50MW. The SWIFTPAC units are configured as multi-trailer modular systems with a majority of the units pre-assembled at the factory. Each unit is designed for rapid installation allowing initial power generation to be achieved within one month upon arriving on site.

PWPS SMALL GAS TURBINES 450kW TO 5MW

PWPS also manufactures reliable, lightweight, environmentally friendly gas turbines in the 450kW to 5MW range with efficiencies that are the highest in their class. All engines are well suited to driving electrical generators as well as mechanical loads such as pumps, compressors or marine drives. High temperature exhaust conditions facilitate effective heat recovery in combined heat and power (CHP) or cogeneration applications. All models can accept gas or liquid fuels.

ST40 GAS TURBINE

Derived from the PW150 aircraft turboprop engine, the ST40 provides power up to 4,904kW (6,576shp). The turbomachinery comprises three independent rotating assemblies mounted on concentric shafts. The compressor is made up of a three-stage axial unit followed by a single centrifugal impeller, each driven by a single stage turbine. Gas or liquid fuel is introduced into the annular combustion chamber through multiple fuel nozzles, and ignited by a high energy surface discharge spark plug. Power is extracted by a two stage turbine, annular combustion chamber, multiple fuel nozzles, and a spark igniter. The engine incorporates a radial air intake which also provides the interface to the reduction gearbox or other driven load.

The ST40 is the base engine for the smallest of PWPS's new line of SWIFTPAC mobile power plants. The SWIFTPAC 4 provides 4MW of mobile power in one ISO shipping container and can be generating power the day it arrives on site.

ST18 GAS TURBINE

This engine is an adaptation of the highly successful PW100 series of turboprops, and is rated up to 2,293kW (3,075shp).

ST6 SERIES OF GAS TURBINES

Four models are available, covering the power range from 450kW to 1,327kW (600shp to 1,780shp). All are based on the well-proven and dependable PT6 series of aviation turboprops, which have accumulated in excess of 200 million operational hours.

PWPS offers complete turnkey power plant systems utilizing these engines. PWPS has an extensive worldwide network of service centres, field representatives, overhaul shops and parts distributors.
