abstract

The combustion turbine industry, especially the cogenerators and independent power producers, would like to commence commercial operations and have the turbine-generators produce steady sources of energy and income streams over the life of the project. Some inexperienced operators have relied on the rated output as a constant over the life of the machine. However, industry experience has shown that combustion turbines have measurable decreases in performance over time. This could cause significant loss of revenues for owners from power sales agreements or cause operators not to be able to achieve the capacity of their machines. Yet, some of this degradation has been recoverable by compressor washing. However, some of this degradation is not recoverable. This paper quantifies extensive experience of non-recoverable measured performance on nine heavy-duty industrial combustion turbines.
