Power plant operators understand that air quality impacts gas turbine performance. For example, gas turbines will foul over time from sub-micron dust penetrating through the filters, leading to a reduction in compressor efficiency. In addition, as air inlet filters load from capturing ambient dust, pressure drop increases and net turbine output decreases. However, few in the industry monitor changes in ambient conditions and accordingly re-adjust maintenance practices.
This white paper examines how monitoring the effects of ambient conditions and filter performance on gas turbine functionality can improve maintenance decisions and reduce operating costs.
