APPARATUS FOR MANUFACTURING POWDER MATERIALS OF A THERMOELECTRIC ELEMENT FOR A BOILER AND POWDER MATERIALS OF A THERMOELECTRIC ELEMENT FOR A BOILER PRODUCED THROUGH THE SAME CAPABLE OF IMPROVING RADIATION AND ABSORPTION EFFICIENCY OF FREE ELECTRONS

摘要

PURPOSE: An apparatus for manufacturing powder materials of a thermoelectric element for a boiler and powder materials of a thermoelectric element for a boiler produced through the same are provided to improve the purity of a thermoelectric element by distinguishing impurities.;CONSTITUTION: An apparatus for manufacturing powder materials of a thermoelectric element for a boiler comprises a melting tank(10), a nitrogen supplying unit(20), a pelletizing chamber(30), and a collection tank(50). The melting tank melts raw materials including Bi, Te, CuBr(Copper(I) Bromide), and antimony. The nitrogen supplying unit evaporates the melted materials. The pelletizing chamber phase-changes the evaporated nitrogen gas into power state. The collection tank collects powdered material.;COPYRIGHT KIPO 2012
