<p>The invention relates to a heat exchanger with cylindrical and concentrical heat surfaces, designed for gas preheating. According to the invention, the heat exchanger which operates based on the Ranque effect, consists of a tube in which occurs the heat exchange; this tube is introduced into another tube, both of them having the ends air sealed with lids; a gas heating agent is introduced tangentially into the inner tube, through a tube with axial discharge, through another tube, both of them of reduced diameter; a gas preheating agent is also introduced tangentially into the outer tube, through a tube, and discharged also tangentially through another tube, all of reduced diameter as well.<IMAGE></p> |
