Abstract
A gas turbine engine combustor section extends axially from a pre-diffuser at a forward end to an aft end relative to an engine axis. The gas turbine engine combustor section includes a combustor liner defining a combustion chamber and a combustor dome situated at a forward end of the combustor liner and affixed thereto. The gas turbine engine combustor section further includes an electrostatic particulate matter collector. The electrostatic particulate matter collector includes a first charged flow guide having an axially forward-most extent aligned with the pre-diffuser and widens radially with respect to the engine axis from the forward-most extent to the combustor dome. The electrostatic particulate matter collector further includes a fuel nozzle extending through the first charged flow guide into the combustor dome. The electrostatic particulate matter collector also includes a power supply electrically coupled to positively charge the first charged flow guide.
