HPI, LLC, a supplier of turbine control, fuel valve replacement and mechanical overhaul services, has acquired U.K-based DLE Aero Ltd., a services firm specializing in Dry Low Emissions/Dry Low NOx (DLE/DLN) mapping. Through DLE/DLN mapping, owner/operators of gas turbines can realize lower emissions and increased combustion efficiency, enabling compliance with more stringent environmental and permitting regulations in the U.S and EU.
By adding DLE/DLN mapping to the company’s broad portfolio of turbine-related services, HPI technicians can analyze performance data from the existing control systems and field devices to determine a turbine’s actual performance. HPI engineers will then calculate setpoint adjustments required to allow the most complete burn in modern DLE/DLN systems, thereby increasing the turbine’s efficiency and reducing NOx emissions. The control system is then reconfigured with new settings to optimize turbine performance. The new DLE/DLN mapping services complement HPI’s mechanical inspections, modifications and repairs, offering owner/operators a complete suite of turn-key services, including fuel system modifications, nozzle replacement, borescope inspections and control system retrofits.
DLE/DLN mapping can be provided on a variety of turbine control systems, whether an OEM-based or PLC system, installed on an industrial frame or aeroderivative turbine. The performance results are available immediately and require minimal downtime without the need to replace any equipment or software.
