INSERTS FOR BURNERS AND RADIANT TUBE HEATING SYSTEMS

摘要

A heating system comprising a tubular member (10, 20, 30), such as a radiant tube, configured to define a combustion chamber and a path for combustion exhaust gas current (G), comprising at least one porous insert (16, 16A, 16B, 16C) which is located in the path of said combustion exhaust gas current, and is adapted to recover heat from said current and transfer said heat to said tubular member or is adapted to transfer said heat to incoming combustion air; applications of the invention include radiant tubes and recuperative burners.
