Flame 5 machine, dual fuel nozzle, spring loaded check valves. Found nozzles some particles like coking material in the fuel oil nozzle dip.
Normally fire with gas, and switch over to fuel oil two week once. Experiencing adjacent TC hit TTHT (low exhaust temp.limit). Request for recommendation on how to prevent fuel nozzle from coking during fuel oil firing.
Thanks.
