Combustion Turbine Blade Temperature Analysis   Need more information?  

Turbine Sentry - Combustion Turbine Blade Temperature Analysis   Improve operating efficiency - prevent premature damage and blade failures in utility combustion turbines

System Overview

Combustion turbine blade temperature analysis can provide a gas turbine operator with a large amount of information about the blades themselves. This information can prove invaluable when refining maintenance procedures and detecting potentially serious problems - thus reducing overall operating costs and increasing efficiency.
Schematic view of a Turbine Sentry system

Use of optical pyrometry in gas turbines
Turbine Sentry uses optical pyrometers to measure blade temperatures, giving significantly better accuracy than traditional methods and showing individual blades clearly.

Predicting and preventing blade failure
Turbine Sentry provides early indication of conditions that could ultimately lead to blade failure. Detection of individual overheated blades give early warning of potential failure, enabling corrective action to prevent costly turbine damage and downtime.

Detection of blade coating failure
In addition Turbine Sentry can detect problems with blade coating, both traditional anti-corrosion and the more modern thermal barrier coatings (TBC), hence allowing the user improved maintenance planning.

This system provides detailed non-contact temperature monitoring of combustion turbine blades for the purpose of engine operation and maintenance.

Benefits of Turbine Blade Temperature Analysis
 
Continuous on-line measurement of individual blade condition
Increased efficiency through improved engine firing rate
Detection of blocked cooling channels
Reliable, accurate blade row temperature
Early warning of potential blade failure caused by over-temperature operation
Continuous monitoring of blade coating condition

Key Features
 
Modular Design - subsystem designs simplify installation and maintenance
Rotor Sentry - single data processing unit, field-expandable to handle up to 32 turbines
Performance - 30 readings per blade for high resolution blade temperature profiles
Reliability - electronics separated from harsh engine environment by fiber optic link


Ease of Use - menu structure PC control, running under Windows NT, for automatic or manual operation


Compatibility - exported tabular data can be used in any spreadsheet program accepting ASCII file format




Turbine Sentry - gives you accurate, high speed analysis of gas turbine temperature data when and where you need it most -in your control room. The powerful, PC based Data Sentry analysis software provides all the tools necessary to identify potential problems at an early stage, whilst also giving a view of plant efficiency.
