Frequency conversions are required when a unit is relocated from a 50Hz system to a 60Hz system or vice versa. Turbine Technology Services Corporation has undertaken numerous frequency conversions on a variety of units and in both directions, the most complex of which was a recent reapplication project of 4 Frame 7EA units to a 50Hz location in the Middle East.

When undertaking a frequency conversion project, TTS considers and reviews a range of items, including:

• All AC Motors and associated driven equipment
• Load Gear modification or installation requirement
• Generator design limitations
  
• Generator excitation and protection requirements
  
• Control system requirements
  
• BOP requirements

Turbine Technology Services has the technical resources and expertise to manage all of these areas and make certain that each is addressed correctly to ensure optimum operation of the unit in its new location.

Fuel System Conversions

In today’s demanding power generation markets, fuel cost and availability have become critical items for most gas turbine users. As such, the ability to switch fuels has become an important competitive advantage.

Turbine Technology Services has extensive experience in the provision of complete fuel conversions for gas turbine units, which allows customers to consider a variety of options, including:

• Liquid to gas or gas to liquid
  
• Single liquid or gas fuel to dual fuel on gas and liquid
  
• Dual liquid or dual gas
  
• Conversion to DLN or Dry Low NOx
  
• Conversion to HFO or Residual Fuel
  
• Conversion to Naphta
  
• Conversion to non-standard or low-Btu gas

Turbine Technology Services can undertake an entire fuel conversion project in all of these scenarios, including using our gas turbine expertise in making diverse hardware and software system modifications required on the existing control systems.

TTS also has the capability to deal with non-standard fuels including Naphta and low-btu gases and to address the combustion system design issues associated with these fuels to ensure the proper operation of your gas turbine and extend its operational lifetime.

Contact us today to request information on how TTS can convert, modify or upgrade your gas engine with these services.

As the international community transitions into a Green Economy driven by sustainable engineering practices, concern for environmental optimization is prompting governments throughout the world to require gas turbine users to reduce NOx emissions from their units.

Such environmental requirements vary from country to country and site to site, and the most cost-effective systems can vary from country to country according to factors such as the availability of resources and the wide diversity of governmental policies.

Turbine Technology Services has extensive experience in the provision of complete emission abatement systems for gas turbine users including both “wet” and “dry” systems. TTS can work with each customer to analyze their required NOx levels and the cost of each potential NOx reduction approach to identify the most cost effective system for each individual case. In addition, we can also provide NOx emission calculations for each of the possible cases to assure the compliance of the system before its installation.

Once the optimum solution has been identified, TTS can undertake the entire conversion including all required hardware and the software system modifications required on the existing control systems or the provision of new systems as necessary.

Contact us today to learn more about how TTS can assist you in the installation or modification of an emission abatement system.

On older gas turbines many of the original auxiliary systems have become obsolete and difficult to maintain. In addition, better versions of these systems have been developed and new systems which further benefit the unit have been designed.

Turbine Technology Services Corporation can provide and install a range of auxiliary system modifications which are fully engineered for your unit. These include:

• Pneumatic or Hydraulic Fuel Valve replacement
• Ratchet Upgrades
  
• Quick Restart Systems
  
• Pneumatic System Modifications (PS&G Panels)
  
• Inlet Misting
  
• Inlet Cooling
  
• Starting Means Modifications
  
• Atomizing Air Modifications
  
• Flow Divider Modifications
  
• Compartment Cooling Modifications

If you currently have problems with existing auxiliary systems or wish to add an additional system, contact us to request from TTS a review of your unit and we will provide the optimum solution for your requirement.
