Abstract
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 lighting and treatment of hazardous waste because it has a highly intense radiant energy. In this paper, we tried to calculate the number density and radiant power density under consideration of absorptive length emitted from atmospheric high temperature air mixed with tungsten vapor to know the basic theory about the effect of absorptive length for the development of the plasma treatment by using radiant power. The mixture ratio of W:N2:O2 is considered as 0, 2.5, 5%:80, 78, 76%:20, 19.5, 19%. The W is dominant in the radiant power density from 6, 000K to 10, 000K, which is calculated under consideration of absorptive length, L=0-1m. There is little absorption in this temperature range at the radiant power from W. The W is still dominant in the radiant power density even if under consideration with absorption.
