Economizers and feed-water heaters are essential components in boiler systems, enhancing fuel economy, increasing steaming capacity, extending boiler life, and reducing pollution by recovering heat from waste flue gases to preheat the feed water. We fabricate various types, including Plain Tubular, Finned, and Cast Iron Gilled Economizers, as well as Feed-Water Heaters and Evaporator Coils. A common issue is the erosion of eco-coil tubes, particularly at bends. To address this, we offer innovative solutions such as Cassette Baffles for bends, Half Tube Sleeves for upper tubes, and SS Full Sleeved Tubes to extend the life and performance of the coils.
