- the gas turbine is operated in this case by means of the fuel and drives ih ⁇ hand, one or more generators.
- the inlet pressure of the natural gas is to be considered. Since the sites of fuel gas production are usually far away from the place of consumers, a corresponding Anliefe ⁇ tion is necessary.
- the fuel gas is first compressed to high transport pressures and the gas pressure is set only at the je ⁇ perige consumption point to the required input pressure value. This inlet pressure is often not constant, but fluctuates.
- pressure control devices are used in current practice, which are able to keep the pressure of the fuel gas, regardless of the fluctuations in the inlet pressure within predetermined limits in one or more controlled systems.
