The DZL Automatic Biomass/Coal Boiler, manufactured by AIX Boiler, a Chinese A-grade producer since 1976, is a horizontal, single-drum, chain-grate boiler that combusts biomass or coal to produce steam or hot water for industrial applications. Its advanced combustion system and automatic fuel feeding achieve thermal efficiency up to 88%, lowering fuel costs. The robust design ensures durability, with fully automated controls for easy operation and low maintenance. Designed for low emissions, it meets environmental standards, making it ideal for industries like textiles, food processing, and power generation. AIX DZL boilers provide reliable, eco-friendly heating solutions.
| Capacity | 2~15t/h |
| Pressure | 0.7~2.5Mpa |
| Fuel | Coal/Biomass |
| Application | Chemical industry, textile plant, rice mill, garment factory, livestock, farm, hotel, school, etc. |
DZL series coal-fired horizontal three-pass water+fire tube chain grate boiler is a packaged boiler. The boiler body is single-drum longitudinal arrangement. The threaded tube is inside the drum forms convection heating surface. The drum and both sides water-cooling wall form to radiation heating surface. The combustion equipment uses light chain grate.
Advanced Structure: DZL boiler adopting threaded fire tubes, single water drum, horizontal shell type boiler with 3 fire-passes structure, water-tube fire-tube mix design. The combustion traveling chain grate can feed the fuels automatically, with different rolling speed can adapt different fuels’ burning speed. Also, the small flakes chain grate can reduce fuel leakage, and also let the broken chain grate flakes is convenience of replace.
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 Ultrasound check, fluorescent penetrating check, hydraulic (water) pressure test, boiler thermal efficiency test,etc, to make sure all finished products is qualified.
Low Fuel Cost: DZL boiler can fire coal, rice husk, nut shell, sawdust, waste wood pieces. Comparing with expensive oil gas fuel, it will markedly reduce user’s fuel consumption cost, increase company’s benefits. Automatic Safe Operation, traveling chain grate can feed the fuel automatically, ash remover can clean the ash automatically
Automatic Control: DZL 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.
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.
