Furnace Wall Temperature Investigation

It is desired to keep the outer metal walls of a heat transfer medium (HTM) furnace warm enough to prevent corrosion. A computational study was carried out in order to assess the normal and lowest possible sheet metal temperatures. Various combustion models, radiation parameters, and operating conditions were considered. Field-measured values matched CFD results closely. It was found that the walls were sufficiently warm under all reasonable modeling approaches and conceivable operating circumstances.
