What it is

The brake plate (diffuser) BN11885801 is a Nuway combustion component for Sterling ST90 oil burners. It sits in the blast tube assembly and shapes the airflow through the burner head, which governs how the oil spray and air mix at the point of ignition. Its condition has a direct effect on flame stability and combustion quality.

Signs this part needs replacing

  • Unstable or pulsating flame that will not settle after normal combustion setup
  • Heavy sooting or blackening of the burner head, blast tube or heat exchanger
  • Visible cracking, distortion, corrosion or erosion of the plate face
  • Repeated lockouts or poor combustion readings that do not respond to nozzle and air adjustment

Before you order

  • Confirm the burner model and variant against the fitment list, as ST90 builds differ in detail
  • Inspect the existing plate for cracking, distortion or material loss before ordering
  • Check that the brake plate and diffuser arrangement on your burner matches the BN11885801 layout
  • Have the burner's identification details to hand when querying the correct component
