Problems solved by technology

However, assembly of the multiple components and their permanent connection to the steam turbine inner casing may complicate future maintenance operations and procedures and complicate and extend the time of steam turbine construction and assembly
Additionally, the multiple components disposed around the inner casing may interfere with and / or block portions of the steam flow path around the inner casing leading to the condenser of the steam turbine system

Embodiment Construction

[0032] Aspects of the invention provide a Steam turbine cowling system. Specifically, the subject matter disclosed in this invention relates to structures configured to thermally insulate steam turbine components (e.g., provide thermal hysteresis, isolate stagnant steam adjacent extremely hot portions of the steam turbine, separate exhaust steam from the inner casing, etc.) and A steam turbine shroud system that serves as a flow guide to a condenser in a steam turbine system by forming a flow path around the inner casing of the steam turbine. The hood system may be shaped to isolate the vapor from adjacent sections of the inner casing, the hood system may include formed / shaped to provide a continuous flow surface (e.g., air dynamic surface).

[0033] As described in this disclosure, conventional steam turbine casings include a number of components disposed on the inner casing to insulate turbine components. However, these multiple components can complicate and lengthen the a...

Abstract

A steam turbine cowling system is disclosed. The steam turbine cowling system including: a lower portion configured to be disposed proximate an inner casing of a steam turbine, and an upper portion connected to at least one of the lower portion and the inner casing, the upper portion shaped to be disposed proximate the inner casing of the steam turbine, the upper portion substantially defining a flowpath about the inner casing. The cowling system is configured as a thermal and flow guide device.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Serial No. 61 / 720,822, entitled "TURBINE COWLING SYSTEM," filed October 31, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The subject matter disclosed in this application relates to the casing of a steam turbine system. More specifically, the subject matter disclosed in this application relates to a cowl system (eg, fabricated sheet metal outer shell) for a low pressure inner casing of a steam turbine system, the cowl system being configured for thermal (eg, thermal hysteresis, thermal insulation, etc. ) and flow guides. Background technique [0004] A steam turbine shell (Shell) is a component that encloses, for example, the high pressure (HP), intermediate pressure (IP) and / or low pressure (LP) Sections of a steam turbine. A conventional steam turbine cowling includes multiple components that may b...
