ABSTRACT
In the design phase of an actual industrial furnace, the main specifications are first determined by integrating the test data, corrected data from scale-up modification of the system, calculation results from model analysis with respect to heat transfer, flow dynamics, and reactions aimed at evaluating the effect of the respective variations from the test conditions. Then the details of the design are worked on. Table 5.1 shows the overall configuration image of the technical arrangements and Table 5.2 the design flow of a high performance furnace as an example of an industrial furnace. The basic concept of the design flow is the same as for a conventional furnace. However, the design of a high performance furnace makes use of various databases which have been compiled as a result of development activities, such as (1) data on the height of the furnace, (2) data on overall heat transfer coefficient (total absorptivity)
φ
, and (3) data on preheated air temperature. Because these data are different from those of a conventional furnace, the final appearance of a newly designed furnace will be altered accordingly.
