Abstract
A honeycomb regenerator for recovering waste heat from exhaust gas, comprises a stacked assembly including at least one first honeycomb body and at least one second honeycomb body stacked thereon, the first honeycomb body being formed of an anti-corrosive material, and the at least one second honeycomb body being formed of a material having a main phase of cordierite. The stacked assembly has an inlet for hot gas and an inlet for cold gas, such that the cold gas flows along a direction opposite the hot gas. Further, the at least one second honeycomb body is provided downstream of the at least one first honeycomb body along a gas flow direction of the hot gas. Accordingly, the at least one first honeycomb body receives the hot gas during flow thereof, while the at least one second honeycomb body receives the cold gas during flow thereof.
