US 2026/0126173 A1 · BUSHING FOR A BURNER TO REDUCE COMBUSTION BYPRODUCTS AND OIL DRIPPING

Abstract

A combustion head assembly for a burner that reduces combustion byproduct and oil pooling on a flame ring stabilizer or air diffuser element during normal operational cycling. The polymeric bushing directs away or prevents a non-combusted fuel in the fuel line interior portion from the nozzle end after a combustion cycle, and is fabricated from a polymeric material having thermal/electrical insulating properties, which is resistant to decomposition, dissolution, or breakdown when exposed to No. 2 fuel oil, biodiesel fuel oil, such as fluoropolymers, including PTFE (Teflon), fluorinated ethylene propylene (FEP), perfluoroalkoxy (PFA), ethylene-based fluoropolymers (ETFE/ECTFE), and/or polyvinylidene fluoride (PVDF), polyether ether ketones (PEEK), polyphenylene sulfide (PPS), and/or fluoroelastomers (FKM), or acrylonitrile butadiene styrene (ABS). The polymeric bushing is situated within a fuel line interior portion behind a nozzle element, having a channel or bore extending from end to end and in fluid communication with the nozzle element opening.

Dependent claims

A combustion head assembly for a burner, comprising:

a fuel line having a nozzle end and an interior portion;
a nozzle element for coupling engagement with the nozzle end, the nozzle element including an opening;
a flame ring stabilizer or air diffuser element proximate the nozzle end and in airflow communication with the burner via an air tube;
at least one electrode for the ignition of a fuel egressing the nozzle element;
and
a polymeric bushing situated within the fuel line interior portion behind said nozzle element, the polymeric bushing comprising a channel or bore extending from end to end and in fluid communication with said nozzle element opening;
wherein said polymeric bushing deters and reduces thermal transfer of heat energy through the fuel line, thereby reducing or eliminating accumulation of oil and combustion byproducts on said flame ring stabilizer and/or air diffuser element, and/or reducing or eliminating oil pooling within said air tube.
