Abstract
Abstract A turbine driven electrical driven generator set having one or more turbines positioned above the generator to provide a power source at locations where there is a minimum available floor space. An acoustical enclosure enclosing the turbine and generator and having air filters for filtering the generator cooling air and the intake air to the turbine. An air fan driven from the generator for cooling the generator and the oil in the turbine and the reduction gearing between the turbine and the generator through an air/oil heat exchanger. The air fan cooling the turbine after shutdown.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A turbine driven electrical generator set comprising, an electrical generator horizontally positioned, a turbine horizontally positioned above and on top of the generator, vertical reduction gearing connected between the turbine and the generator, an acoustical enclosure enclosing the turbine and the generator including air filters for filtering the generator cooling air and the intake air to the turbine, an air fan connected to and driven from the generator, auxiliary power means to drive fan after turbine shutdown, an enclosure enclosing the turbine and the generator including a partition between the turbine and the generator, said partition including an openable passageway in communication with the fan inlet for being opened for cooling the turbine after shutdown.

Claim 3
Dependent Claim
145 words
A turbine driven electrical generator set comprising, an electrical generator horizontally positioned, a turbine horizontally positioned above and on top of the generator, vertical reduction gearing connected between the turbine and the generator, an air fan connected to and driven from the generator for drawing cooling air through the generator, an air/oil heat exchanger having an air inlet and air outlet and connected to the oil in the turbine and the reduction gearing, and positioned with the exchanger air outlet adjacent the air fan inlet for air cooling the exchanger, the exchanger air inlet positioned to receive cooling air separate from the cooling air passing through the generator, and an acoustical enclosure enclosing the turbine, the generator, and the heat exchanger including air filters for filtering the generator cooling air, the air intake to the turbine, and the cooling air to the exchanger air inlet.
