<p>HEAT EXCHANGE WHEEL MOUNTING A heat exchanger and mounting structure therefor for use in connection with incinerators, for example, the heat exchanger formed of a ceramic wheel with a central core and an annular portion with gas passages extending axially therethrough. The ceramic wheel is mounted at the central core with a mounting means which comprises first and second wedge members in abutting relationship with opposite sides of the core. Means bias the wedge members towards each other so that the core is resiliently held under compression between the two wedge members to eliminate tension stresses on the ceramic wheel due to thermal expansion differences between the ceramic wheel and the mounting structure therefor. The mounting structure includes a first shaft secured to the first wedge member and a second shaft, tubular in shape and concentrically mounted on the first shaft, the second shaft being secured to the second wedge member. The shafts are supported on the cool side of the heat exchanger wheel by a pair of bearings. Cooling air is circulated through the interior of both of the shafts and through the bearings to keep the mounting shafts and the bearings as cool as possible.</p> |
