DZH Manual Biomass/Coal Boiler

The DZH Manual Biomass/Coal Boiler, manufactured by AIX Boiler, a Chinese A-grade producer since 1976, is a horizontal, single-drum, fire-tube boiler designed for manual feeding of biomass or coal to produce steam or hot water for industrial applications. Its efficient combustion system achieves thermal efficiency up to 85%, reducing fuel costs. The robust design ensures durability, with simple operation suited for small-scale industries like textiles, food processing, and agriculture. With low emissions, it meets environmental standards, offering a cost-effective, eco-friendly heating solution with reliable performance.

Steam Capacity 500 to 6,000 KG/H
Boiler Power 32 to 384 HP
Pressure ≤16 BAR
Fuel Biomass, Wood, Coal

 

Features

  • High Quality Control: In manufacturing processes, we has adopting steel strength test, automatic steel cutting/ plate rolling/ welding, 100% x-ray welding check, magnetic particle check c-scan ultrasonography check, fluorescent penetrating check, hydraulic (water) pressure test, boiler thermal efficiency test,etc, to make sure all finished products is qualified.

  • Simple Structure: DZH boiler adopting threaded fire tubes, single water drum, horizontal shell type boiler with 3 fire-passes structure, water-tube fire-tube mix design. Most important, the combustion fixed chain grate can also suit any kind of biomass. The small flakes chain grate can reduce fuel leakage, and also let the broken chain grate flakes is convenience of replace.

  • Better Adaptability on Fuels: Comparing with DZL boiler, DZH boiler has better adaptability on fuels, it can fire coal, rice husk, nut shell, sawdust, waste wood pieces, also can fire wood logs, straws. But, DZH boiler can only support manual fuel feeding, and manual ash remove.

  • Safe Operation: DZH series is equipped with automatic water-level control, automatic pressure control, automatic interlock chain stop protection, free settable working pressure, visible system’s working states on screen.

Application

It can be applied to the municipal gas pipeline, oil refineries, chemical plants in petroleum and petrochemical industry, metallurgical industry, power industry or any place that is possible to have gas leakage.
