Radiant power with absorption emitted from line spectrum of high temperature air contaminated tungsten vapor

Summary form only given, as follows. When a reduction of the waste and dissolution of the iron are carried out by using a high temperature medium, the radiant power emitted from it should be suppressed. On the contrary, it is useful for lightning and treatment of hazardous waste because it has a highly intense radiation. In this paper, we tried to calculate the mass density and radiant power density emitted from atmospheric air contaminated with tungsten vapor to apply the radiant power to treatment of hazardous wastes. The contaminated mol ratio of W/N/sub 2//O/sub 2/ is considered as 5%/76%/19%, because it is assumed that the high temperature air contaminated with tungsten is generated by free arc discharge of 1,700 W. The W is dominant in the mass density and radiant power density from 6,000 to 10,000 K. And then, the radiant power densities with absorption are calculated. The W is still dominant in the radiant power density even if with absorption. On the other hand, the N and O decrease if the absorption is considered. At the end, the application of the radiant ´power emitted from high temperature atmospheric air with tungsten vapor is proposed.
