Abstract
An improved system, apparatus and method may be configured for detecting coking in a gas turbine engine. The system may comprise one or more heatable collecting elements configured to be positioned in a fuel supply passage having an inlet and an outlet. The apparatus heatable collecting may be configured to generate heat at or over a fuel system temperature range to induce coking in at least one of the heatable collecting elements. The apparatus may also include a sensor configured to detect an indication of coking on the heatable collecting elements and, in response to the coking indication, communicate a coking condition signal to an engine control.
