DEFINITION

Classification: 431/207

(under the class definition) Apparatus including a line feeding fluid to a flame holder and having (1) a means other than the flame at the flame holder for heating a section of the line, or (2) an arranged by which the fed flame holder heats a distinct section of the line by which it is fed or

feed material while it is within the feed line.
