Finned tubes in boiler economizers utilize waste heat from flue gas to preheat boiler feedwater, thus saving fuel; while in air preheaters, finned tubes heat the combustion air, improving furnace efficiency. Both recover waste heat, but their functions differ. Economizers typically use durable materials to withstand water-side conditions, while air
The core characteristic of high-frequency welded finned tubes lies in their unique high-frequency induction welding process. High-frequency current instantly melts and fuses the fins to the base tube, forming a metallurgical-grade weld with a minimal heat-affected zone, ensuring high welding strength and low thermal resistance. Their heat transfer efficiency is
