Reactor feed tube adjustable mounting assembly and method

摘要

A mounting assembly 4 is provided for a feed tube 12 of a high-temperature fluid-wall reactor of the type having a vertically oriented reactor tube heated to incandescence for emitting radiation radially inward to a reaction zone. The mounting assembly 4 comprises a tube support 34 having an opening 42 through which the feed tube 12 can pass, and a pivot seat member 30 secured to the reactor. The assembly 4 further comprises a retainer 52 for selectively fixing the orientation of the feed tube relative to the reactor, and a releasable attachment mechanism 70 for allowing the axial position of the feed tube to be adjusted relative to the assembly 4. According to the method of the invention, undesirable conditions within the reactor are detected, and the orientation of the feed tube is pivotably adjusted in response thereto for reducing undesirable reactor operating conditions.
