Outer-wall box for the combustion-air and waste-gas duct of an apparatus operating with a burner system

摘要

In an outer-wall box for the combustion-air and waste-gas duct of an apparatus operating with a burner system, in particular for mobile spaces, a cylindrical box chamber (32) is subdivided by a partition wall (33) into an upper compartment for the waste-gas stream and a lower compartment for the combustion-air stream, and the cylindrical box chamber (32) is constructed so as to form with its circumferential wall (43) a connection piece (44) for the combustion-air duct (45), and for the waste-gas duct (41) a connection piece (40) is attached to the rear wall (35) closing the upper compartment (34) for the waste-gas stream. <IMAGE>
