SPIRAL COIL COOL WALL CONSTRUCTION FOR HIGH TEMPERATURE CYLINDRICAL FURNACES, VESSELS, CYCLONES, ETC.

摘要

A vessel for separating entrained particles from a gas in which a vertically extending tubular portion extends through a portion of a housing for providing an outlet for the gas after separation from the particles. The tubular portion includes a tube formed into a spiral coil, and a continuous fin extends from the tube for the entire length of the tube. The fin is welded to adjacent sections of the tube to render the coil airtight. A layer of insulation material extends to both sides of the coil.
