Abstract:
1. A heater having microchannels, comprising: an upper plate including an inlet of material to be heated, a fuel inlet and an oxidant inlet; a lower plate including a heated material outlet and an exhaust gas outlet; a plurality of combustion plates; and a plurality of heat transfer plates, wherein the combustion plates and the heat transfer plates are alternately layered between the upper plate and the lower plate, wherein each of the combustion plates and each of the heat transfer plates has an inlet hole of the material to be heated, a heated material outlet hole, an oxidant hole, an exhaust gas hole, and a fuel hole, wherein the exhaust gas hole and the fuel hole of the combustion plate are connected by a first plurality of microchannels, wherein the inlet hole of material to be heated and the heated material outlet hole of the heat transfer plate are connected by a second plurality of microchannels, wherein the combustion plate further has a fuel supply portion, which is linked with a fuel supply hole connected to the fuel hole of the heat transfer plate, to supply fuel thereto, wherein the upper plate and a combustion plate, of the plurality of combustion plates, which is in contact with a lower surface of the upper plate, are disposed such that the inlet of material to be heated, the fuel inlet, and the oxidant inlet of the upper plate are aligned with the inlet hole of material to be heated, the fuel hole, and the oxidant hole of the combustion plate, respectively, and wherein the lower plate and a heat transfer plate, of the plurality of heat transfer plates, which is in contact with an upper surface of the lower plate, are disposed such that the heated material outlet and the exhaust gas outlet of the lower plate are aligned with the heated material outlet hole and the exhaust gas hole of the heat transfer plate, respectively, and wherein the microchannels of the combustion plates are coated with an oxidation catalyst.
