Abstract

A trailer mounted mobile power generation system provides electrical power at locations where it is needed, either separate from or as a supplement to power from an electrical power distribution grid. A jet engine, a free turbine and an electrical power generator in a single common road transportable trailer. The trailer complies with weight and height limitations imposed by transportation authorities. The jet engine drives the turbine, which in turn drives the electrical power generator. Power levels on the order of 20 megawatts are generated while maintaining noise and combustion product emission levels within presently specified regulatory limits.

Claims

1. A mobile, trailer-mounted power generation system comprising:

a gas generator burning a hydrocarbon fuel for creation of combustion gases;

a free turbine operably interconnected with the gas generator as a first turbine stage to receive combustion gases and rotate a turbine shaft in response thereto;

an electrical generator in communication with the free turbine for the generation of electricity upon rotation of the turbine shaft;

a trailer body having a floor on which the gas generator, free turbine and electrical generator are mounted, end and side walls and a roof;

the gas generator, free turbine and electrical generator each having a longitudinal axis about which their components rotate during their operation;

the longitudinal axes of the gas generator, free turbine and electrical generator being longitudinally aligned along a common axis along the longitudinal extent of the floor of the trailer body;

the trailer body having an air inlet near one end for passage of air to the gas generator;

the free turbine having an exhaust for exit of the combustion gases; and

the trailer body having a combustion gas outlet formed in a side wall thereof for exit of the combustion gases.

2. The power generation system of claim 1 wherein the gas generator comprises a jet engine.

3. The power generation system of claim 1 wherein the free turbine comprises a UGT 2500 turbine.

4. The power generation system of claim 1 wherein the free turbine comprises a FT-4 turbine.

5. The power generation system of claim 1, further including an elbow member turning the flow of combustion gases from the longitudinal axis of the free turbine to exit from the gas outlet in the side wall of the trailer body.
