Selection of fins for stainless steel plate-fin heat exchangers used for waste heat recovery from dust-containing flue gas

Thread Content

Stainless steel plate-fin heat exchangers are typically composed of partitions, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent partitions to form a layer known as a channel. By stacking such layers in different arrangements according to the properties of the fluid and welding them together, a plate bundle is created. The plate bundle is the core component of a plate-fin heat exchanger; when combined with necessary end caps, tubes, supports, etc., it constitutes a complete plate-fin heat exchanger. The main components of a typical plate-fin heat exchanger include fins, partitions, seals, guide vanes, and end caps. https://gss3.bdstatic.com/-Po3dSag_xI4khGkpoWK1HF6hhy/baike/c0%3Dbaike92%2C5%2C5%2C92%2C30/sign=876952a408e93901420f856c1a853f82/962bd40735fae6cd803941e506b30f2443a70fa1.jpg Common types of fins used in stainless steel plate-fin heat exchangers include serrated, porous, straight, and corrugated types. For flue gas containing dust, triangular fins of the straight type are used, as this helps to reduce resistance and prevent ash buildup. The fin height is set at 9 mm, allowing for regular cleaning
