摘要：

Low-emissivity ovens have linings of epsilon(e) < 0.1 that enhance the thermal radiation exchange between sheathed electrical heating elements (that are exposed within the cavity) and the thermal load(s). These ovens are a quick and energy-efficient alternative to conventional ovens; however, due to the high levels of thermal radiation, they must be carefully designed and controlled so that uneven radiation distributions over loads are minimised. In this paper, a Monte Carlo ray-tracing model was employed to undertake a parametric analysis of low-emissivity ovens. The factors that influence the magnitudes and uniformities of radiation distributions occurring over loads are identified, and recommendations for optimal heating configurations and control algorithms are presented.
