Design of Atmospheric Gas Burners

Robert P. Jackson, PE

This eight hour course is intended to provide an in depth discussion for the design of atmospheric gas burners. We will discuss the various burner parts, their function and how those individual parts interact with each other. We will also discuss the overall burner relationships within an assembly of components; i.e. gas distribution system, support structure(s), ignition system etc. The basic design principals are governed by formulas developed over the years for defining the following relationships:

  • Gas pressure vs. profile of converging / diverging passageways
  • Flame speed vs. flame ejection velocity
  • Port loading vs. number of ports
  • Percent primary air vs. percent carbon dioxide in products of combustion
  • Primary air vs. flame appearance
  • Gas type vs. flexibility of burner deign
  • Throat diameter to port area ratio
  • The effects of gas/air temperature on complete combustion
  • The distance of the orifice from the burner throat vs. the ability of the burner to aspirate the gas/air mixture
  • Port spacing vs. lifting, flashback and floating of individual burner flames
  • Orifice alignment vs. ability of burner to eject mixture at ports and achieve complete combustion

  • We will demonstrate the formulas governing these relationships by working an example where a burner is designed from start to finish.

    This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
