Brief Introduction

DZL series coal/ biomass fired boiler is a traveling chain grate type steam boiler, can realize it can realize automatic fuel feeding, automatic ash removing. Additionally, it can reach super low emission, as equipped with a dust collector and air purification device. Because of its steady performance and low fuel consumption, make it is popular in the market. DZL is the most popular product in Southeast Asia, Central Asia, and Africa.

Product Application

Textile, Garment, Food & Beverage, Chemical Industry, Cement Curing, Disinfection, etc.


High-Quality Control: In manufacturing processes, we have 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 tested, to make sure all finished products are qualified.

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 speeds can adapt different fuels’ burning speeds. Also, the small flakes chain grate can reduce fuel leakage, and also let the broken chain grate flakes is convenient of replace.

Low Fuel Cost: DZL boiler can fire coal, rice husk, nutshell, sawdust, waste wood pieces. Comparing with expensive oil gas fuel, it will markedly reduce user’s fuel consumption cost, increase the company’s benefits.

Automatic Safe Operation: Traveling chain grate can feed the fuel automatically; ash remover can clean the ash automatically.
Also, the 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.
