Class Information
Number: 431/350
Name: Combustion > Flame holder having protective flame enclosing or flame stabilizing structure
Description: Apparatus including a fuel discharge device specialized to combustion by (1) an enclosing means forming a combustion chamber having an unmodified discharge; (2) structure protecting the discharge means or its surroundings from localized heat produced by the combustion of the discharged fuel and not of general utility for protection in the discharge of any hot fluid; or (3) means for maintaining a steady flame.
