Water Tube Steam and Hot Water Boiler

Why choose
Water Tube Steam and Hot Water Boiler?

The series boilers merge leading international technologies, designed by a team with rich experience. They feature a horizontal, double-drum, longitudinal type design suitable for steam and hot water production, representing the high-end of boiler technology.

Structurally, the boilers are available in quick-install and assembly forms to accommodate different scale demands. The 2-4t/h models offer quick installation for immediate use, while the 6-25t/h models are divided into two main parts to ensure flexibility in transportation and on-site assembly. The front end's water-cooling wall and the rear's dense convection tube bundle efficiently absorb and transfer heat, while the emissions pass through economizers and dust collectors to optimize efficiency and meet environmental standards.

This series combines the convenience of quick-install boilers with the stability of assembly types, with a more compact structure offering single-layer boiler room configuration, significantly saving space, reducing installation times and costs, and simplifying operations. These steam boilers are widely applied in industrial production and civil heating, providing users with an economical and efficient thermal energy solution.

Boiler Features

Engineered by experts leveraging advanced domestic and international technologies, aligning with top global environmental and performance standards.
Quick and simplified setup with pre-assembled 2~4t/h quick-install water tube structures and modular 6~25t/h assembly for easy transport and installation.
The boiler integrates a water-cooled front wall to absorb combustion radiation heat and densely arranged convection tubes for high thermal efficiency through secondary heat exchange.
The 20t/h boilers are modular, including front and back furnaces, convection tube bundles, economizers, and chain grates, ready for whole-unit assembly.
Designed for space-saving with a single-layer boiler room layout, it offers quick installation, low costs, and user-friendly operation.
Versatile for both industrial steam production and residential heating with corresponding hot water boiler capacities.
