General Product Information

Optimization of temperature control

One of the innovative solutions offered by Siemens Power Service to help you improve the performance of your gas turbine and thereby your competitiveness is the Control Optimization of the Corrected Outlet Temperature.

The Control Optimization of the Corrected Outlet Temperature is a closed-loop turbine control process that uses compressor inlet temperature, engine exhaust temperature and engine speed as main control parameters for the gas turbine. These critical parameters are used to formulate a relationship to control the turbine to a corrected exhaust temperature, taking into account variations in ambient temperature and engine speed.

 

The Control Optimization of the Corrected Outlet Temperature Corrected provides significant performance advantages and offers attractive financial payback options.

Your benefits
