Steam Turbine Agility

Automated start-up control, revised permissives, and rotor stress management using Model-Based Control to enable fast, repeatable steam turbine start times.

Attemperator Control

Model-based control of attemperation flow to better regulate steam temperature during start-up and transients, enabling more stable operation, fewer trips, and improved efficiency.


Automation of the HRSG blending process to better manage steam temperature and flow when bringing additional gas turbines online in combined cycle plants. This enables more stable operation, fewer trips, and more energy production for the lead gas turbine.

HRSG Boiler Response

Improved setpoint management and tuning of HRSG drum level control to enable more stable operation during starts and transients, and fewer trips.

SCR Control

Model-based control of Selective Catalytic Reduction (SCR) system ammonia flow to enable enhanced operation during start-up and transients, resulting in less ammonia slip and lower overall NOx emissions.

Steam Turbine Fast Cooldown

Automated fast cooldown process using temperature matching logic in reverse, to safely reduce ST cooldown times by 50% or more, enabling critical path maintenance activities to begin 24 to 36 hours sooner.

Start-up NOx

Advanced combustion control to enable low visible emissions above full speed no load and reduced cumulative start-up NOx emissions.
