Abstract
A device (1) for the feed of air to a compressor (2) of a gas turbine plant has an air inlet duct (8) and an air inlet chamber (9) which adjoins the air inlet duct. For the purpose of damping sound emissions of the compressor (2), a first and second inner wall (10, 11) of the inlet chamber (9) is at least partially lined by means of melamine foam. The invention is characterized by the advantages in that silencing is ensured both with wetness and with chemically aggressive conditions. The silencing device is consequently functionally reliable over an extended operating period.
