Achieving operational flexibility is critical to maximizing output and environmental effects


Achieving operational flexibility is critical to maximizing output and environmental effects

Automated and fully customizable

The ECOMAX combustion tuning platform provides an automated, fully customizable solution to achieve customer-determined operational objectives. This patented technology continually monitors and adjusts key combustion control parameters to maintain NOx and CO2 compliance, flame stability, and acceptable combustion dynamics.

The ECOMAX® system provides operators with:

  • Customizable operational goals
  • Emissions management and compliance
  • Combustion dynamics control and mitigation
  • Increased fuel flexibility
  • Improved allowable load operating range
  • Continual optimization
  • Increased power potential
  • Controls upgrades that are not mandated
  • Eliminated manual tuning requirements

Extensive benefits from each component

Plant operators gain extensive benefits from each component of the solution.

Because ECOMAX® operates using real-time continuous operational data, Combustion Dynamics Monitoring Systems (CDMS) and Continuous Emissions Monitoring Systems (CEMS) are required. However, plant operators can now control their plants without third-party input and specific plant operating information – that is critical to plant optimization – can be housed and adjusted on-site.

We can make tailored adjustments to meet the following objectives:

  • Combustion dynamics mitigation
  • Exhaust emissions compliance
  • Optimization of station power and efficiency
  • Maximization of station availability and reliability

Control emissions and manage your combustor dynamics

Rising to the challenge of DLN tuning.

Burning a lean premixed flame keeps NOx emissions low but results in acoustic instability in the gas turbine. In time, this instability (combustor dynamics) will damage components in the combustion chamber (nozzles, liners, transition pieces) or even downstream components (nozzles, blades), causing unnecessary downtime, increased equipment repair costs, and loss of generating revenue.

Ambient temperature changes can strongly affect combustor stability. Historically, this problem was addressed via seasonal tuning. Tuning is necessary to achieve the best balance between NOx, CO, combustor stability, and dynamics.

However, a better solution is available, whereby the user could monitor the performance of a gas turbine combustor without bringing a tuner to the site. A necessary tool is a Combustion Dynamics Monitoring system (CDMS) that allows the acoustic behavior of each combustor to be continuously observed and documented.

Helping you achieve optimal operating objectives

Pre-set on/off toggle switches allow for easy and immediate switching between operating modes. The plant operator can specify an operational directive for a given situation while maintaining the constant ability to switch turbine settings. This is done to achieve different operational parameters easily, immediately, and at the operator’s complete discretion.

A CDMS continuously monitors dynamics and relays this information to ECOMAX® either directly or indirectly. A standard configuration has the DCS continually monitoring emissions data and sending this information to ECOMAX®. Using real-time CDM, CEM, and turbine performance data, ECOMAX® determines when tuning adjustments are necessary and automatically tunes the turbine to suit the operator’s optimization goals.

Continually optimizing your performance with Tru-Curve

Tru-Curve is a process that occurs when ECOMAX® raises the turbine’s baseload fuel-to-air ratio while simultaneously managing both emissions and combustor dynamics within acceptable levels. It safely optimizes the baseload performance of an operator’s plant when they deem it advantageous, and can remove this effect whenever required.

Your combustion dynamics monitoring system

Combustion Dynamics Monitoring Systems (CDMS) prevent high dynamic amplitudes that can cause damage to components. The acoustic behavior of each combustor is continuously observed and documented. These systems have the additional benefit of indicating changes in dynamics associated with hardware failure. This allows users to pinpoint combustor issues and take action before additional failure or damage occurs.

Permanent CDMS have been developed for continuously monitoring dynamics. These systems provide round-the-clock monitoring so that tuning changes can be made whenever necessary. There are two basic types: low-temperature auto-purging and high-temperature non-purging systems. The difference between the two is the location of the sensor with respect to the turbine compartment.

Both systems provide the ability to tune as needed and each can receive an early indication of damaged combustion hardware. This raises the potential for operators to run a turbine at its optimum setting in real-time, allows preventative maintenance, extends combustion parts life, and can help increase maintenance intervals.

CDMS is a necessary tool required to run ECOMAX® automated tuning technology.
