Compressor Wash

Gas turbine compressors consume approximately 60% of the overall cycle energy during operation. This cycle consumes very large quantities of air and although this air is filtered, small quantities of dust, aerosols and water pass through the filters and deposit on the blades. These deposits decrease the air flow of the compressor and the overall performance of the gas turbine. Compressor cleanliness can be maintained using a routine program of water washing. There are two water wash maneuvers performed on gas turbines: offline and online. An offline maneuver is conducted with the gas turbine in a cooled state using cranking speed, while an online maneuver is conducted with the machine at operating temperature and uses water only. Both operations use highly atomized water spray patterns designed to completely enter the compressor core. The offline process cleans the entire core and recovers lost performance, while the online cleans the early stages and maximises the time period between needed between offline washing to provide peak availability.

The patented GTE highly atomised compressor wash system will offer the gas turbine operator the following improvements while using the GTE online/offline compressor wash system:

Benefits / Demonstrated Improvement

• Availability: ~ 2 %
• Performance/Output: ~ 3 %
• Heat Rate: ~ 1 %
• Payback: a few months

The GTE compressor wash system is proven on more than 800 stationary gas turbines, most of which OEM makes, such as GE, Siemens, Rolls-Royce, and others. The experience totals more than 20 million hours of gas turbine running time.

 

Technology

GTE is has redefined gas turbine cleaning technology with new methods and are committed to continuous research and development. The development of the GTE highly atomized direct injection system has allowed engine cleaning to achieve a giant step forward in providing a cost-effective and environmentally-adapted method that gives substantially improved results. The washing is done with de-ionized water only and the need for hazardous chemicals has been eliminated. Previous washing technology was done by simply spraying water and chemicals through a hose directed towards the engine blades or using intrusive shepards hooks inserted behind the fan of an engine. These processes were time consuming, environmentally unfriendly, inefficient and unsafe.

Power Generation Applications

The increased average power output and heat rate is obtained by minimizing the daily degradation due to compressor fouling by running a daily online compressor wash schedule. After increasing the gas turbine efficiency, the exhausts will be cleaner and help pollution control. Payback is typically just a question of months. Installation and operation is very simple and well received by our customers.

The GTE patented highly atomized online/offline wash is individually developed for each type of turbine following a design procedure that is well established and proven. It includes 3D modeling of inlet and nozzle positioning, CFD (Computational Fluid Dynamics) to study droplet trajectory, and confirm and evaluate nozzle positions. GTE equipment can be made ATEX EEXD Zone-1 classed for refinery and other hazardous area applications. An integrated control panel enables easy user operation.
