Abstract

The roles of reflectors and a substrate in the circular lamp heating furnace are systematically evaluated, for the first time, using the direct application model using the ray trace simulation. The rays emitted from the lamp are concentrated and distributed in the region of the concentric circle formed by the cylindrical reflectors, in order to improve the heat intensity and heat uniformity. With increasing reflectivity of the substrate surface and with increasing the distance between the light source and the substrate, the ray intensity absorbed by the substrate decreases and its profile tends to be flatter. The rays emitted from the heated substrate surface can reach near its emission site. The heat loss at the outer region of heated substrate is evaluated to be larger than that at the inner region.
