Why More Industries Are Replacing Plate Coil with Wide Channel Pillow Plate Heat Exchangers?

Image
 For more than two decades, Plate Coil heat exchangers have been widely used in industrial waste heat recovery applications. They have been commonly applied in steel plants, cement kilns, chemical processing, and power generation systems due to their simple structure, ease of manufacturing, and relatively good heat transfer performance. However, in recent years, a clear shift has emerged: More and more new projects are no longer defaulting to Plate Coil heat exchangers. Instead, they are moving toward a different solution: Wide Channel Pillow Plate Heat Exchanger This trend is especially obvious in industries such as waste-to-energy plants, biomass boilers, biodiesel production, palm oil processing, sugar refining, and alumina refining. In many EPC discussions, this technology is now even referred to as: Plate Coil Replacement Solution 1. Industrial Fluids Are Becoming More Complex Compared with 20 years ago, industrial heat transfer conditions have changed significantly. Mod...

Efficient Waste Heat Utilization: The Investment Return Logic Behind the Revamp of a Steel Tunnel Furnace Heat Exchanger

S teel production is a precise calculation of “temperature.” From the 950°C charged billet to the 1180°C discharge and the furnace’s extreme limit of 1300°C, every degree of heat carries high fuel costs. However, a large amount of waste heat is often discharged directly into the workshop – a clear signal that a professional waste heat recovery heat exchanger is missing. This not only worsens the working environment but also steadily erodes profits. Recently, an internal report from the QSP hot rolling line of a major Vietnamese steel company disclosed a practical, quantifiable, and return-clear retrofit plan: upgrade the existing steel tunnel furnace heat exchanger system and add recovery units in areas currently without any recovery. This plan does not chase the “zero-carbon” slogan, but focuses on directly measurable fuel savings and investment returns – a field where Ukada heat exchanger manufacture brings deep expertise. I. Pain Points: Temperature Drop and “Naked” Heat Discharg...

Indonesia's B50 Biodiesel Expansion: Why Spiral Plate Heat Exchangers Are Becoming Critical Equipment in Palm Oil Refineries and Biodiesel Plants

Image
Recent news indicates that with the advancement of Indonesia's B50 biodiesel policy, the government plans to gradually reduce and eventually stop diesel imports. For most people, this might just be another piece of energy industry news. However, for those working in palm oil, biodiesel, and industrial equipment sectors, this signals new opportunities and challenges across the entire supply chain. As the world's largest palm oil producer, Indonesia is actively pushing forward the B50 policy. Under this policy, every 100 liters of diesel will contain 50 liters of palm oil-based biodiesel. To meet growing market demand, increasing volumes of palm oil will be further processed into fatty acid methyl esters (FAME), biodiesel, glycerin, and other downstream products. Behind every capacity expansion, there is usually a corresponding need for equipment upgrades. Over the past few years, we have engaged with many palm oil refineries, biodiesel plants, and oleochemical companies. Many cu...
