The vast majority of natural gas burning appliances used in the domestic and commercial markets incorporate laminar flame burners. Conventionally, these burners are made up of a number of ports, in the form of slots or holes, which give rise to multiple laminar flames which may or may not interact depending upon the particular burner design. In addition, because of the flame stability and gas interchangeability problems encountered when using non-premixed flames, virtually all current burners use premixed natural-gas air mixtures that give rise to partially or fully aerated flames.
