  laboratory as a source of heat. This burner is
  designed so that gaseous fuel may be mixed with
  the correct amount of air to yield the maximum
  amount of heat. In order to use this burner
  properly and safely, it is essential that you
  understand its construction and the adjustments
  that can be made.

• The principal parts of the burner are
• needle valve
• collar
• barrel
• The quantity of gas admitted to the burner is
  controlled by the needle valve, while the air
  needed for combustion is admitted at the small
  opening around the bottom of the barrel call air
  intake openings. The air is controlled by turning
  the collar so as to make the air holes larger or
  smaller.
