What temperature does the BEA heater heat air to maintain fuel viscosity?

The correct temperature for the BEA (Burner Efficiency Air) heater to maintain fuel viscosity is 60 degrees. This temperature is crucial for ensuring that the fuel maintains the appropriate viscosity for optimal atomization and combustion within the gas turbine system. If the fuel is too viscous, it can lead to poor atomization, resulting in inefficient combustion and a potential decrease in engine performance. Conversely, if it is too thin, it may lead to issues such as excessive evaporation and an increased risk of fuel leakage. Therefore, maintaining the heating air at 60 degrees strikes a balance that promotes effective combustion while also ensuring the fuel system operates smoothly.

The other temperature options do not align with the specifications required for maintaining adequate fuel viscosity within operational parameters for gas turbines.
