Turbomachinery Package Specification Titan 250 Generator Set
2 Titan 250 Gas Turbine Generator Set
2.1 General Description
The Titan 250 gas turbine generator set (Figure 1) is a completely integrated and fully
operational package equipped with all accessories and auxiliary systems required for
operation. In addition to the standard package features, a wide array of optional
equipment is available to meet the customer’s installation and operation requirements.
Designed specifically for industrial service, Solar’s gas turbine generator sets are
compact, lightweight, and require minimal floor space for installation. Proven packaging
designs greatly reduce installation costs, time, materials, and labor.
The package features a radial exhaust resulting in a short overall package length that
conserves valuable mounting space.

2.2 Package Description
The gas turbine generator set consists of an axial-flow gas turbine engine, generator, and
reduction-drive gearbox. These components are installed in-line on a two-piece heavy-
steel base frame referred to as the skid. The skid is a structural steel assembly with
beam sections and cross members welded together. The two sections of the skid can be
separated to facilitate handling and shipment but when bolted together they form a rigid
structure suitable for three-point mounting. Drip pans are included to collect any potential
liquid leakage. Package connection points for fuel, lube oil, air, and water are located on
the outer edge of the skid.
Electrical connections are made in onskid junction boxes. Machined mounting surfaces
on the skid facilitate component alignment. The gearbox is bolted directly to the engine
and coupled by means of a splined interconnecting drive shaft that eliminates the need
for field alignment. The gearbox and generator are connected by means of a flexible
dry-disk, shear-type coupling enclosed in a coupling guard. Jacking points are provided
to facilitate alignment of the generator to the gearbox.
