Heat exchanger for the transfer of the thermal energy of a hot exhaust gas stream is heated to a gaseous medium

摘要

There is a narrow position at which the gas acquires a high speed and at the dividing wall (2) receives a good heat transfer. After the turning point the space volume (2a) enlarges. By reason of the existing eddy the heat layering is mixed and the eddy prodn. at the narrow position and the connecting space volume expansion is repeated (1a) in counterflow procedure on the other side of the dividing wall (2). At the input of the hot gas (4) through the bending arrangement of the dividing wall (2) the space volume is enlarged across the complete width. USE/ADVANTAGE - To overcome the problem with known heat exchangers in which high blower pressure is necessary with corresp. high energy usage.
