ABSTRACT:
The technical field of the invention is that of manufacturing heat treatment apparatuses such as furnaces for thermally cracking chemical substances, in particular hydrocarbons. The present invention provides a method of heat treating one or more fluids flowing along a duct including at least one rectilinear tubular portion extending along an longitudinal axis and optionally terminated by at least one bend, and disposed at least in part in a thermal enclosure, in which method, in order to reduce or avoid the deposition of solid particles on the inside wall of said duct, said duct is caused to vibrate by means of a mechanical vibrator which is located outside the thermal enclosure, and which is connected to the duct by mechanical link means; according to the invention, said vibrator exerts a force on said mechanical link means substantially along an axis that is transverse relative to the longitudinal axis of said rectilinear length, and said mechanical link means is fixed to said bend or to said rectilinear length in the vicinity of an end thereof.
