Abstract
Abstract A separating device and method, particularly for removing moisture particles from air entering the air intake of a gas turbine for ships, comprises two separating means through which the air flows consecutively, namely a first separating means in the form of an impact filtering pad (1) and a second separating means in the form of an inertia separating means (2) (e.g. vanes). The impact filtering pad (1) is preferably comprised of layers (7) of crimped knitted mesh (5) of fibres (6), each fibre having a diameter greater than .001 inches and less than .006 inches and the ratio of the total surface area of the fibres in the pad being greater than 45 ft<-><1> and less than 1400 ft<-><1>.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A method of removing particles entrained in air, the air including particles of moisture, in which the air is passed consecutively through a plurality of separating means for removing particles from the air including an inertia separating means and an impact separating filter pad, characterized in that the first separating means through which the air is passed is an impact separating filter pad (1) and in that air from said pad is then passed through an inertia separating means (2).
Claim 2
Independent Claim
80 words
A method of removing particles entrained in air, the air including particles of moisture, in which the air is passed consecutively through a plurality of separating means for removing particles from the air including an inertia separating means and an impact separating filter pad, characterized in that the first separating means through which the air is passed is an impact separating filter pad (1) and in that air from said pad is then passed through an inertia separating means (2).
Claim 3
Dependent Claim
31 words
A method according to claim 1 characterised in that the impact separating filter pad (1) and the inertia separating means (2) are the only separating means through which the air passes.
Claim 4
Dependent Claim
74 words
A method according to claim 1 or 2 characterised in that the impact separating filter pad (1) comprises at least one layer of a plurality of fibres (6), each fibre having a diameter greater than .001 inches and less than .006 inches, and the ratio of the total surface area of the fibres in the pad to the volume of the pad being greater than 45 ft 1 and less than 1400 ft .
Claim 5
Dependent Claim
80 words
A separator assembly for an air intake duct of a turbine device for removing particles, including moisture particles, from air being introduced into said turbine device, comprising a plurality of separating means for removing particles from the air including an inertia separating means and an impact separating filter pad and an impact separating filter pad, characterised in that the first separating means is an impact separating filter pad (1) and the next separating means is an inertia separating means (2).
Claim 6
Dependent Claim
80 words
A separator assembly for an air intake duct of a turbine device for removing particles, including moisture particles, from air being introduced into said turbine device, comprising a plurality of separating means for removing particles from the air including an inertia separating means and an impact separating filter pad and an impact separating filter pad, characterised in that the first separating means is an impact separating filter pad (1) and the next separating means is an inertia separating means (2).
