TTS Delivers Gas Turbine Emissions Reduction Systems to 2 Power Plants

Source: 10/5/2023, Location: North America

TTS Power, a division of TTS Energy Services, recently designed, built, and delivered two (2) water injection systems for Alliance Energy at two sites in Middletown, NY, and Hillburn, NY. The customer’s goals were to meet new emissions standards as directed by the state of New York.

Skid Design
The system was designed to provide each Pratt and Whitney FT4A gas turbine engine in a TwinPac configuration with controlled amounts of water up to 33GPM. The water injection mechanical components (including pressure switches, VFD-controlled motors, filters, flow meters, and pressure transmitters) were packaged into a single skid with a single inlet (from a TTS-supplied water forwarding skid) to a dual outlet for each engine. The flow to each engine is controlled by VFDs that receive their signal from the TTS-supplied remote I/O junction box near the skid.

Controls modifications
TTS integrated the new system into the customer’s Allen Bradley control system. The system utilized TTS standard logic blocks for water injection that were modified for this purpose. The control’s I/O was expanded using fiber optics to the new junction box and integrated into the existing ControlNet bus. TTS provided a new HMI interface screen that displays critical operating parameters. This screen was integrated into the original Wonderware HMI.

The overall project was considered a success. The customer had a limited timeframe to implement the water injection system and depended on TTS’ engineering calculations to meet the emissions standards. Time and budget constraints meant that creative solutions had to be developed to meet delivery and performance requirements. TTS’ customer Said: “TTS was presented with many challenges during this project and met our required delivery and performance requirements. Overall, it is a very successful project that will allow these peaking assets to continue supporting the bulk electric system in times of high demand.”
