Dear all,
my colleagues and myself are in charge of detailed engineering a gas turbine project. The gas turbine will be located oudoor, in a hot and sunny region.
A this stage of the project, we will have to specify the painting color expected on the inlet and filtration duct.
Based on previous field experience, some people suggest that a white color is the best choice from a performance perspective. Because of its low radiation absorption coefficient, a white inlet duct is less sensitive to solar radiations.
According to some former operators, an inlet duct painted in white would slightly reduce the temperture of the air ingested by the compressor. On hot summer days, the benefit on compressor inlet temperature could reach up to -1°C, which would also mean addtional power output.
I am personnally not convinced that external color of the duct may really influence compressor inlet temperature... but it is not easy to bring a clear and convincing demonstration.
Any comment and operating feedback on this matter would be helpful.
Thanks to all of you.
