Abstract

"In heat transmission by radiation, it is very easy to find the heat transmitted from one surface to another. Much work has been done in this area. The problem becomes complicated when the two surfaces are enclosed or joined by an enclosure. Such problems frequently arise in the design of furnaces. One problem is linked with the economy of fuel, by proper consideration of heat losses through the openings in furnace walls such as doors and burner openings. A second problem is associated with the heating capacity and useful heat transfer through the openings such as heat ports in walls or perforations in arches or muffles. The performance of refractory walls is of interest here.

In heat transmission through surfaces enclosed by refractory enclosures, the problem involves not only direct radiation between source and sink but also the heat reradiated from the enclosing walls. The amount of reradiation depends upon the geometry of all the surfaces involved. The complication of the problem still increases due to the fact that the temperature of the refractory enclosure varies from point to point. The usual method is to assume a temperature for the reradiating walls comparable with experience. This could be the mean temperature of the source and sink or some other approximate method.

The purpose of this paper is to illustrate a method to account for reradiation by enclosure walls. A special case of cylindrical enclosure with disc type source and sink at the ends is considered here. The same method can be applied to enclosures of different shapes with appropriate modifications in dimensions and view factors. Specifically it is desired to determine the temperatures of the refractory surface at all points and compare this temperature with some of the usual assumptions"--Introduction, pages 1-2.
