GAS TURBINE ENCLOSURE
A gas turbine enclosure apparatus is provided and includes a frame defining an interior, gas turbine equipment disposed in the interior, the gas turbine equipment being pre-assembled at a first site and connectable with a gas turbine disposed at a second site and wall panels connectable with the frame. The apparatus being disposable proximate to the gas turbine such that the gas turbine equipment is exposed to the gas turbine and a portion of the wall panels form a portion of an outer enclosure of the gas turbine and the gas turbine equipment.
The subject matter disclosed herein relates to a gas turbine enclosure. More particularly, the subject matter disclosed herein relates to a gas turbine enclosure formed of pre-assembled modules.
Gas turbines generally include a compressor, a combustor and a turbine section. The compressor is configured to compress inlet air which is then mixed with fuel and combusted in the combustor to form a high temperature and high pressure working fluid. The working fluid is received in the turbine section where it is expanded to generate mechanical energy. This mechanical energy is used to drive rotation of the compressor and may be employed in the production of electricity. Gas turbines are often coupled to a substantial number of components, such as piping, valves, electrical devices, etc., and enclosed within an enclosure that provides for sound attenuation.
In gas turbine assembly processes, the various components of a gas turbine are shipped to a site where the gas turbine is to be built and assembled at the site. Since the site is often located at a remote area where the gas turbine operations will not disturb the local population, costs associated with the shipping and the labor needed to complete the assembly processes may be substantial. In addition, any issues confronted during the on-site assembly processes often cannot be easily corrected. In the case of faulty components, the components need to be shipped back to their factory and replacement parts need to be re-shipped to the assembly site. This adds to the time and labor costs associated with normal assembly processes and can also lead to delays in construction schedules.

The apparatus being disposable proximate to the gas turbine such that the gas turbine equipment is exposed to the gas turbine and a portion of the wall panels form a portion of an outer enclosure of the gas turbine and the gas turbine equipment.
According to another aspect of the invention, a gas turbine enclosure apparatus is provided and includes a frame defining an interior, gas turbine equipment disposed in the interior, the gas turbine equipment being pre-assembled at a first site and connectable with a gas turbine disposed at a second site and permanent acoustic wall and temporary shipping container panels connectable with the frame. The apparatus is disposable proximate to the gas turbine and stackable with another apparatus such that, with the temporary shipping container panels removed from the frame, the gas turbine equipment is exposed to the gas turbine, and the permanent acoustic wall panels form a portion of an outer enclosure of the gas turbine and the gas turbine equipment.
According to yet another aspect of the invention, a gas turbine enclosure apparatus for enclosing a gas turbine is provided. The apparatus includes a plurality of modules comprising at least one or more module types. Each module includes a frame defining an interior, gas turbine equipment disposed in the interior, the gas turbine equipment being pre-assembled at a first site and connectable with a gas turbine disposed at a second site and wall panels connectable with the frame. A portion of the wall panels of each module of the plurality of modules are configured to cooperatively form a portion of an outer enclosure of the gas turbine and the gas turbine equipment.
These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings.
The subject matter, which is regarded as the invention, is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
The detailed description explains embodiments of the invention, together with advantages and features, by way of example with reference to the drawings.
DETAILED DESCRIPTION OF THE INVENTIONThe accessory piping, valves, electrical and other components of a gas turbine to be assembled are packaged within modules that arrive at the site of the gas turbine pre-assembled and commissioned. This pre-assembly enables faster plant erection, reduced erection cost and reduced quality defects.
With reference to
While a plurality of pre-assembled modules are pre-assembled at a first site 1, as will be described below, the gas turbine 10 is disposable at a second site 2. The second site 2 may be remote from the first site 1. At the second site, the gas turbine 10 is supported on a base 14.
Each one of the plurality of pre-assembled modules may be assembled at the first site 1 and the plurality of pre-assembled modules includes at least one or more module types. Typical modules may include a fuel control module 20 (see

As noted above, since the gas turbine equipment 23, 33, 43 and 53 is pre-assembled into the various modules, on-site assembly processes are limited to connections between the gas turbine equipment 23, 33, 43 and 53 and the gas turbine 10. This can result in substantial reductions in field welding, field installed components and valves, and connections between turbine supplier and plant installer piping systems.
In accordance with aspects and, with reference to
In accordance with further embodiments of the invention and, with reference to
In accordance with embodiments, the pre-assembling of operation 210 includes pre-assembling a fuel control module, pre-assembling an air extraction module, pre-assembling a drainage module and pre-assembling an additional air extraction module. In accordance with further embodiments, the method may include installing gas turbine work platforms within the outer enclosure (operation 215), supporting a grating on a portion of the plurality of modules (operation 216), defining one or more maintenance access points in the outer enclosure (operation 217) and attaching a roof portion to the outer enclosure along with any remaining panels required to complete the outer enclosure (operation 218).
While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
