Computational fluid dynamics (CFD) software can help to improve burner positioning and understand process fluid mechanics and heat transfer for better furnace performance.
Many high-temperature industrial heating processes suffer from poor temperature uniformity, inefficient or unknown cycle times, poor burner placement and inefficient heat transfer. In many cases, increases in furnace productivity, product quality and a reduction in specific fuel consumption can be achieved by improving burner positioning and understanding process fluid mechanics and heat transfer to a greater degree. The use of computational fluid dynamics (CFD) software, such as Fluent® (registered trademark of Fluent Inc., Lebanon, N.H.), is a valuable design and analysis tool for the heat processing engineer to accomplish these objectives. Two illustrative examples demonstrate the power, effectiveness and useful insight that CFD tools can provide in analyzing various industrial-heating applications.
