TITAN 130 INDUSTRIAL POWER GENERATOR 15mw

 

 

 

 

 

 

 

 

 

BASIC PACKAGE

 

The Titan 130 Industrial Power Generator (IPG) is a compact, rugged gas turbine generator set that has been designed to meet the requirements for industrial power generation applications.  The unit is provided as a completely integrated module ready for installation.  The gas turbine engine, gear box, generator, control system, fuel system, lubrication system, start system, and ancillary equipment are included in the package. 

 

Features included in this proposal are:

 

Base.  The base provides structural support for the Titan 130 gas turbine engine, gear box, generator, enclosure, and all operating systems.  The base is manufactured by Solar using structural steel with welds per AWS D1.1.  Approximate overall dimensions are:

 

                        48 feet, 0 inches (14,629 mm) long

                        10 feet, 4 inches (3,150 mm) wide

 

Approximate height of package is 11 feet, 3-1/2 inches (3,438 mm) and may vary with ancillary equipment and generator selection.  Four lifting gussets are provided.

 

Drip pans are welded beneath the package frame to collect potential liquid spills.  The drip pans also provide a tight seal for containment of fire suppression agent for packages supplied with an enclosure.

 

Piping.  All tubing and piping up to 4 inches nominal diameter is stainless steel.  Package piping is designed and fabricated to ANSI B31.3.

 

Tube Fittings.  All tube connections use compression fittings.  Tube fittings are zinc plated carbon steel or 316 stainless steel.

 

Note:  Throughout the proposal, all references to the package orientation (left, right, clockwise, counterclockwise, etc.) are based on standing at the "aft" (e.g. turbine exhaust) end of the package looking forward.

 

Electrical System.  The Titan 130 IPG generator set is designed to comply with the requirements of the National Electrical Code and is intended to be installed in a non-hazardous location per NFPA 37.

 

Unless otherwise noted package motors and heaters are rated for 460 Vac, 60 Hertz, 3 phase.  Except where indicated, contactors and motor starters are not included.

 

Unless otherwise noted single phase loads are rated for 120 Vac, 50 - 60 Hertz.

 


GAS TURBINE ENGINE

 

The Titan 130 gas turbine engine is a single shaft, axial flow engine.  The output gearbox, including accessory drive pads, is a separate, close-coupled unit located at the inlet end of the turbine.

 

 

The engine assembly consists of:

 

     Gear unit with accessory drive pads

     Air inlet collector with flexible flange connection

     Axially split case in the vertical plane, 14 stage axial flow compressor with variable geometry control on inlet guide vanes and first three rows of stators

     Annular combustor with 14 fuel injectors

     Three-stage turbine assembly

     Turbine exhaust collector

 

The components of the Titan 130 engine are maintained in accurate alignment by mating flanges with pilot surfaces and are bolted together to form a rigid assembly. The speed reducing gear box is driven by the compressor rotor shaft.  Accessory pads drive the main lube oil pump and other accessories, depending on the application, and supports the starter motor.

 

The gas turbine output shaft is mechanically coupled to both the compressor and turbine sections of the engine to form a "solid" or "single" shaft configuration.  This feature enhances speed stability and response under constant and varying load conditions -- a highly desirable feature in generator applications requiring precise frequency control.

 

Inlet Orientation.  The gas turbine air inlet flange terminates in the up position.

 

 

SPEED REDUCING GEARBOX

 

The speed reducing gearbox is an epicyclic star-gear industrial design manufactured to Solar's design specifically for the Titan 130 IPG generator set.  The gearbox mounts directly on the Titan 130 gas turbine to reduce engine speed to 1800 rpm (60 Hz).
