OPRA manufactures the OP16 model which is an all-radial, single-shaft industrial gas turbine designed and manufactured specifically for power generation applications in the 1600 – 2000 KW range. It utilizes an unique turbine wheel of single-stage, radial configuration while all other gas turbines in the OP16 power range have a multi-stage, axial configuration with combinations of stator and rotor blades. The all-radial design results in the OP16 being significantly shorter in length and permits a more compact turbine-generator package.
Air is compressed by the single-stage centrifugal impeller operating at 26,000 RPM.
The OP16 gas turbine is rated at 1900 KW shaft power at ISO conditions. When driving a generator rated at 97% efficiency, the OP16 shaft horsepower translates to 1840 KW electrical power.
For an ambient temperature of 15°C, the electric efficiency of single gas turbine is about 26.2% while the combined heat plant efficiency reaches 92%.
