Inbed Coil Headers – Engineered for Efficient Heat Exchange Inbed Coil Headers by Steamtech Boilers are precision-fabricated components used in fluidized bed combustion (FBC) boilers for effective heat transfer and improved combustion efficiency. Designed to withstand high temperatures and abrasive environments, these headers distribute water or steam evenly through the inbed coils, playing a critical role in energy recovery and boiler performance. Manufactured from high-grade alloy or carbon steel, our inbed coil headers are custom-built to meet client specifications and ensure seamless integration with modern boiler systems.
