Overview

EN 299:2009 (CEN) specifies a standardized method for determining the spray characteristics and the index angle of oil pressure atomizing nozzles used in liquid-fuel burners. The method uses a radial patternator to capture radial distribution data and derives cumulative volume percentages to compute index angles and to classify spray pattern types. The standard improves repeatability versus visual or photographic angle measurement.

Key Topics

  • Test equipment: a cylindrical radial patternator with 14 concentric dividers and graduated collection cylinders, plus a vertically adjustable nozzle holder mounted on the lid.
  • Test setup: the nozzle orifice is positioned at an axial distance of 50 mm from the upper bevelled edges of the dividers. Testing is performed with the reference oil specified in EN 293.
  • Sampling volume: the total atomized volume per test shall be at least 80 ml and sufficient to provide representative liquid volumes in the collection cylinders.
  • Data processing: recorded tube volumes are converted to cumulative percentage volumes and correlated with the plane angles subtended by each annular compartment. Continuous radial distribution is represented in tabular or graphical form.
  • Index angle definition: the standard defines the index angle as the 80% angle - the inner cone angle within which 80% of the collected liquid volume is contained. This angle is computed by interpolation between compartments that bracket the target cumulative percentage.
  • Angle ratio & classification: a 50%/80% angle ratio provides a measure of spray uniformity. The index of pattern type (I–IV) is assigned using the 50%/80% ratio thresholds:
    • I: > 0.700 - solid
    • II: 0.700 to 0.749 - semi-solid
    • III: 0.750 to 0.799 - semi-hollow
    • IV: ≥ 0.800 - hollow

Applications

  • Burner manufacturers: validate nozzle designs and rating labels to ensure consistent flame shaping and combustion performance.
  • Quality control: routine production testing to confirm spray pattern conformity and stability over manufacturing lots.
  • R&D and selection: compare nozzle types (solid vs hollow patterns) for optimization of atomization, combustion efficiency, and emissions control in oil-fired equipment.
  • Certification and standards compliance: provide repeatable, auditable test evidence for conformity with European nozzle performance expectations.

Related Standards

  • EN 293 - referenced normative document that specifies the reference oil and minimum requirements/testing for oil pressure atomizing nozzles.

EN 299:2009 emphasizes reproducible measurement of radial spray distribution and index angles to reduce variability caused by visual or photographic angle determination. The radial patternator method delivers objective, quantitative data for nozzle classification and performance verification.
