The buyer must provide liquid fuel that is clean, filtered and compliant with general electric specification mid-td-0000-2.
All necessary shutoff valves, flow meter, piping and instruments between the auxiliary trailer skid connection and the engine are included.
Buyer must provide supply piping with sampling ports, fuel system filtration and applicable shut-off valves and containment per local codes and standards.
Water injection system: the equipment package is capable of water injection for nox reduction.
For full-load operation, the demineralized water must be supplied to the auxiliary trailer skid connection at 28 gpm (106 l/min), 15 psig (103 kpag) minimum, 40 to 140 °f (4 to 60 °c) filtered to 10 microns.
The buyer must provide demineralized water that is clean, filtered and compliant with general electric specification mid-td-0000-3.
All necessary shutoff valves, flow meter, piping and instruments between the auxiliary trailer skid connection and the engine are included.
Buyer must provide supply piping with sampling ports, fuel system filtration and applicable shut-off valves and containment per local codes and standards.
Lube oil systems: the equipment package is supplied with two separate lube oil systems; one for the gas turbine and one for the generator.
The oil reservoirs and piping are all stainless steel, and the lube oil system valves have stainless steel trim.
Each lube oil system has a pump, simplex filters, necessary valves and instrumentation, and thermostatic-controlled electric heaters.
A dual fan, single core fin fan cooler is provided to cool turbine, generator lube oil and hydraulic oil.
The cooler is mounted on the auxiliary trailer and the rest of the lube oil systems are mounted on the main trailer.
Buyer must provide any additional containment per local codes and standards.
Switchgear: the equipment package is supplied with a 3 section nema 3r switchgear enclosure.
The switchgear includes a set of generator circuit breaker equipment, 2 sets of incoming line voltage monitoring equipment, a marshaling cabinet and a set of switchgear accessories.
Permanent cable terminations from the neutral and line-side of the generator are also included.
