Abstract: It is desired to keep the walls of a heat transfer medium (HTM) swirled-burner furnace warm enough to prevent corrosion. A computational study was carried out in order to assess the normal and lowest possible wall temperatures, specifically those of the sheet metal layers making up the outer wall. 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 to prevent corrosion under all reasonable modelling approaches and conceivable operating circumstances. A dramatic computational time savings can be realised by employing a thermal-only solution for certain modelling permutations.
