A power producer shared the story of their successful project to upgrade their generation capacity and modernize their control system and improve communications and control with the wastewater treatment plant supplying water for steam generation. The upgrades included wet compression and duct burners to decrease NOx and CO2 emissions. The upgrade replaced a older DCS with an Ovation system on their steam turbine control system and PLC at the water treatment plant.
Combustion turbine exhaust Is used to Heat a Boiler (HRSG)* and generate steam that is used to rotate the steam turbine blades. The water used in the generating process comes from the local municipal water company, onsite wells, and reclaimed water sources. The grey water is pumped in and used as cooling tower water. The cooling tower basin is where the water is treated. The cooling tower blowdown is discharged back to the source.
The grey water source creates several challenges:
Ovation OCC100 controller
To address these challenges, the solution was the Installation of the Ovation OCC100 controller, which:
Communications and overall performance between the wastewater treatment and power plants have been robust and reliable for over three years.
