Newington Energy Contractual Services contracted with VEETech, P.C. and WSL and Associates to perform an inspection of the Selective Catalytic Reduction (SCR) Nitrogen Oxides (NOx) control systems on two GE Frame 7 combustion turbines installed at Newington Energy’s facility in Newington, New Hampshire.

The Newington Energy Facility is a 525 megawatt (MW) combined cycle power plant in Newington, NH. The Newington Energy facility consists of two GE frame 7 FA combustion turbines with two supplementary-fired Heat Recovery Steam Generators (HRSG) and one steam turbine in combined cycle configuration. The combustion turbines are designed to fire natural gas or low sulfur No. 2 distillate oil. The gas turbines have low NOx combustors, and the HRSGs have SCR systems for emissions control.  The SCR systems employ anhydrous ammonia (NH3) as the reagent. The systems provide storage, vaporization, transfer, and injection control for the ammonia gas injection at the SCR catalyst bed gas inlet.
