Abstract
A separator assembly with an integrated structural frame, on which the separator assembly and any required ancillary equipment are mounted. The frame is adapted to be secured in an air inlet, e.g. of a gas turbine. Thereby, rigid and correctly positioned mounting of the separator assembly in the air inlet is facilitated.
Description
SPECIFICATION
Integrated structural frame
The present invention relates to an integrated structural frame, and more particularly, but not exclusively, to an integrated structural frame for use with a separation assembly for a gas turbine for landborne or marine applications.
For example, the integrated structural frame of the present invention is particularly useful as a rigid frame enclosure for moisture and/or particle separators for removing moisture and/or particulate matter entrained in the air entering the air intake of a gas turbine of a ship.
Various types of moisture separator systems are used to remove salt and solid particulates from the inlet air to gas turbines.
Many of these separators are mounted in ships and off-shore platforms where shock and vibration loadings are very high. To improve the structural integrity of these systems, it is advantageous to contain them within a rigid structural frame capable of re-enforcing the surface upon which they are mounted.
One such frame is described in the present invention.
Gas turbine moisture separators are required to perform continuously under adverse conditions, without any degradation in efficiency.
This mandates that they meet both performance and rigid structural requirements. In order to meet both of these stipulations, they must be rigidly contained, have a minimum amount of deformation, and provide a solid sealing surface. These parameters are satisfied by utilizing the present invention.
The present invention consists of a series of structural members, so fabricated, as to provide a rigid support upon which to mount a fixed or movable moisture separator assembly together with all ancillary equipment. This structural frame is designed and fabricated to eliminate the requirement for a flush or straight mounting surface for the moisture separator system. It is intended to accept all operational loads and stresses incurred by the moisture separator system. The frame may be bolted or welded to the primary structure with the welded joint being the preferred method of attachment. Materials used in the fabrication of the present invention are many and varied, depending upon the imposed conditions that the device is intended to withstand.
Any plastic or metallic material may be utilized in its fabrication.
It is the object of the present invention to provide an improved means for assembling and testing the separator system at the fabrication site and an improved means for installing the separator system at the operating site, said separator system consisting of the moisture separator assembly and the integrated structural frame with members and components, including, by way of example, any one or combination of the following::
a mounting frame means;
a mounting means, whether fixed mounted, pivotally or hinged mounted, or slidably mounted, for mounting the separating means to the mounting frame means;
a sensing means for sensing the pressure differential of the air across the separator means;
a clamping means for normally clamping said frame means;
a power-applying means, whether pneumatic, hydraulic, electric or manually operated, for moving the separating means from the closed to the open position and return;
a holding means for holding the separating means in position;
a manual or powered actuator means for moving the separator means from the open to the closed position;
a sealing means for effecting a positive seal between the sealing flange of a separating means and a mounting frame means with the said separating means in the closed position;;
a differential pressure switch or controller means for automatically moving the separator means to the open position through the power-applying means; and
a quantity of mechanical and electrical devices necessary to form a complete and contiguous assembly including, by way of example, rods, clamps, lines, brackets, fittings, linkage, wiring, heating elements, and similar such devices.
Our U.S. Patent No. 4,312,645 describes a simplified separator assembly for an intake duct of a turbine device for normally removing particulate matter entrained in air being introduced into the said turbine device.
Our U.K. Provisional Specification No.
8412594 describes alternate separator means which allow air to bypass the said separating means when necessary.
The following is a description, by way of example, of embodiments of the present invention, reference being made to the accompanying drawing in which a typical integrated structural frame is shown in Fig. 1.
The moisture separator system shown is illustrative only and depicts movement in the direction of air flow. It is also possible for the structural frame to be mounted such that the moisture separator may move in the counter flow direction or in any other desired direction or directions.
The separator assembly, by way of example, may be fixed mounted, pivotally or hinged mounted, or slidably mounted to the present invention thereby providing a complete, strong and rigid integrated assembly supporting the said separator assembly and primary structure without deflection, distortion or deformation, and with an improved positive seal of the separator assembly to the present invention.
In the illustrated embodiments, a separating assembly 1 is rigidly supported in an integrated structural frame 2 with a peripheral sealing surface 3 which can be seated against a gasket 4 round an opening 5 in a mounting member 6 in the form of a plate at the inlet entrance 7 of an air duct of a gas turbine.
The direction of the air stream is indicated by an arrow 8.
All operating and retaining members and components of the separator assembly are exclusively supported by the structural frame of the present invention such that no additional supporting means are required on the primary structure. This feature permits the fabrication of a complete integrated assembly consisting of the separator assembly and the present invention combined into one system providing for, by way of example;
ease of assembly and test at the point of fabrication;
no subsequent disassembly at the point of fabrication for shipment to the site of operations;
no reassembly at the site of operations with attendant risk of assembly and test errors, including development of a poor seal to frame through deflection, deformation or distortion;
reduction in time for installation at the site of operations with resultant cost savings; and
elimination of the need for making costly, time consuming, accurate alignments and realignments of the system components at the site of operations.
The combined system is furnished by the fabricator as a complete, fully assembled, fully tested, operational system, eliminating the need for assembly and test at the site of operations, thus ensuring that the system as fabricated and shipped is qualified to meet all the imposed loading conditions.
