• Dirt accumulation found on combustion engine check valves at an upstream oil and gas facility

What did GE's analytics software find?

In December, the GE SmartSignal solution detected spiking cylinder exhaust temperatures. This caused the exhaust temperature spread to increase values as high as 572°F (300°C) with estimates remaining near 86°F (30°C). GE’s Industrial Performance & Reliability Center (IPRC) added this item to the weekly report for discussion with the customer.

 

What was the underlying cause?

Upon investigation, the customer found that it was not a coil or spark plug issue as initially assumed, but that the check valves needed cleaning. During the next planned shutdown, the check valves were cleaned and the IPRC verified that the exhaust temperatures returned to normal.

 

What was the value to the customer?

Due to the early notification from the IPRC, the customer was able to plan the required maintenance and prevent unnecessary downtime. Continued operation with the dirty check valves would have severely decreased the performance of the combustion engine.

In December, cylinder exhaust temperature (blue) started deviating from expected values (green). The unit was shut down, and upon start up cylinder temperature remained stable and exhaust temperature spread returned to expected values.
