What is the acceptable amount of CCFD in gas turbine systems?

The acceptable amount of CCFD (combined cyclic fuel degradation) in gas turbine systems is critical for ensuring optimal performance and longevity of the turbine components. The figure of 2.64 mg/L represents the maximum allowable concentration at which the gas turbine can operate effectively without risking damage to the internal components or impairing performance. This value is derived from a balance of factors including fuel quality, combustion efficiency, and maintenance practices that have been established through industry standards and operational experiences.

Maintaining CCFD levels at or below this threshold helps in preventing the build-up of contaminants within the fuel system, which could lead to issues such as fouling of fuel injectors or combustion chambers, thereby enhancing the overall reliability and efficiency of the turbine. Monitoring and managing this parameter is essential for ensuring optimal operation and avoiding unnecessary repairs or downtimes.
