ATOMIZING CENTRIFUGAL AIR COMPRESSOR
Centrifugal compressor air atomisation is a new product in Romania fitted in industrial gas turbines for big power used in electricity production, to reduce pollutants emitted by these turbines.
Such a compressor takes 2 ... 3% of the flow of air compressed by the gas turbine compressor and it raises the pressure with a compression of about 1.5. This flow of air is introduced into injectors of the combustion chamber increasing in this way the quality of atomisation, and also a reduction of pollutants from the combustion process.
The result of project is the beginning of construction in series of Centrifugal compressor air atomization:
- Type Compressed gas: air
- Input Pressure: 178 psia (12,27 bara)
- Compression Report: 1,5
- Drive speed: 6600 rpm
- Flow rate: 5,9 pps (pound/sec) (2,67 kg/sec)
- Input temperature: 225 grd F (107,22 grd C)
In the frame of the project the following main activities has been achieved:
- Mathematical modeling for fluid dynamic calculations to optimize compression cycle in accordance with customer requirements;
- Documentation of performance and technology for functional model;
- Stand design and implementation, including the measurement of parameters;
- Realization of component parts and design, assembly and functional prototype;
- Experimentation, tests and certification of the stand with the functional model.
