ECOMAX - A DLN Automated Solution for GE Frame 7FA A combined cycle facility located in the arid desert region of the southwest United States experiences significant changes in the daily ambient temperature. The extreme environmental shifts, which can range between 35-40°F, cause turbine combustion systems to operate inefficiently and swing from emission compliance limits to conditions that could cause flame blowouts Compressor Water Wash System on 2 x GE Frame 7EA Gas Turbines With ever increasing requirements to operate and maintain existing gas turbine assets at their highest efficiencies, the staff of Direct Energy’s Paris, Texas Generating Facility began identifying options to improve overall plant efficiencies. Internal and external contaminants cause blades and vanes to foul which can lead to surging, blade corrosion, erosion, and significant Compressor Water Wash System on 2 x GE Frame 6B Gas Turbines A combined cycle plant located in Thailand and positioned near sea level in a high humidity and a pollution laden environment had been practicing conventional low pressure offline wash cycles. Overall performance monitoring illustrated continued rapid gas turbine output degradation, forcing an offline wash frequency of approximately every 1000 hours. Multi-Stage Compressor Cleaning System on 2 x GE Frame 9E TNB Sultan Ismail Power Station (PAKA) operates four simple cycle GE Frame 9E units. These units were cleaned twice a year at overhauls with abrasive materials. The ever increasing requirements to operate and maintain existing gas turbine assets at their highest efficiencies, instigated the staff of PAKA to begin identifying options to improve overall plant efficiencies. Multi-Stage Compressor leaning System on SW501F Cleco Evangeline, an intermediate load following power plant, is located in rural, central Louisiana and is the Siemens LTP SGT6- 5000F (SW501F) class engine operational hour’s fleet leader. The engines experience compressor fouling from seasonal, environmental and agricultural conditions, such as pollen and prescribed burning of local sugarcane and cotton fields, resulting in loss performance. Case Study: Innovative Component Solutions DTE energyEnergy®, a North American utility, was searching for a service provider that could meet their unique business challenges. Facing three back to back outages for 7EA turbine, no spares to support the outage schedule and capital expenditure constraints, DTE Energy® chose Wood Group GTS as their solution provider. Control System Retrofit Case Study A Central American electric utility was in search of a control system retrofit solution for their liquid fuel fired Frame 6 unit. The utility faced control system related issues experienced by many mature technology turbine owners: control system obsolescence and reliance on the original manufacturer for support. |
