Gas Process Turbine GTT- 9 based on the modernization of the installation GTT-3M with current approaches in the design, allowing to get the required parameters in a much smaller number of steps and a more reliable design concept. Installation GTT- 9 used to produce nitric acid in the ehnergotehnological lines UKL -7.
Competitive advantages and design features
- Increased efficiency of at least 5%
- Increased service life of more than 40 %
- Reducing the complexity of repair work on 50 %
- A high efficiency fuel ( natural gas consumption required to produce the same amount of nitric acid is reduced by 10 % compared to the GTT- 3M)
- Changing the flow of air through the blades in the range 85-105 % of the rated capacity, due to the rotary inlet guide vanes
- Ensure the necessary degree of compression stages 9 instead of 17
- Ensuring compressor drive for n = 7500 r / min with three turbine stages
- Maximizing the temperature protrusions discs max 360 °C
- Ensuring efficiency turbine at the inlet gas to 800 °C
- Increasing the blade service life more than 2 times, through the use of nano-structured coating turbine blading
- Having a stock temperature before the turbine for forcing parameters and operation of a wide range of atmospheric conditions while maintaining high productivity and pressure
- The presence of new sliding bearings with metal-fluoroplastic tape for easy replacement and repair of sliding bearings
