Patent ID: 6938405

Claim:
Water mister apparatus for supplying humidified air to a compressor forming part of a gas turbine, comprising: an air inlet duct for supplying air to the compressor; a plurality of manifolds arranged in the air inlet duct for communication with a supply of water and extending in a direction generally normal to the direction of air flow through the duct to the compressor, said manifolds extending between opposite walls of the duct and in spaced arrays thereof in the direction of air flow through the duct to the compressor, manifolds of each array thereof lying in substantial alignment with manifolds of other arrays thereof in the direction of air flow through the duct to the compressor; a plurality of nozzles in communication with each of the manifolds; a first set of said plurality of nozzles extending in a downstream direction from a downstream array of manifolds; a second set of said plurality of nozzles extending in a downstream direction from manifolds of said plurality thereof arrayed intermediate an array of upstream manifolds of said plurality thereof and said downstream array of manifolds; a third set of said plurality of nozzles extending in a downstream direction from said upstream array of manifolds; said first, second and third sets of nozzles of said downstream, intermediate and upstream arrays of manifolds, respectively, terminating substantially in a common plane extending across said duct and generally normal to the direction of air flow through the duct.
