QXS Horizontal Package Corner Tube Gas Hot Water Boiler
- Boiler proper utilizes self-supporting horizontal corner tube structure, with high strength & stability, safe and reliable without shaking or surging.
- Hot water boiler has no drum. Drum is in external and unheated without numerous densely expansion (welding) pipe holes.
- Hot water boiler utilizes forced circulation + natural circulation (auxiliary. Single drum layout offers a greater height difference than traditional products, ensuring safer water circulation.
- Convection heating surface utilizes smooth tube + spiral fin tube structure, providing ample heating surface area in the boiler proper, and the rear section is equipped with economizer and condenser (air preheater) for high thermal efficiency.
- Reserving sufficient space between densely heated surfaces for inspection & maintenance makes easy entry & exit of furnace & furnace chamber, making inspection & maintenance more convenient.
- Horizontal structure fully assembled before delivery with low shipping cost, less installation workload and short installation period.
