Brief Introduction

DZL coal/ biomass fired traveling chain grate boiler realizes zero pollution with the use of special dust collector solution (water film dust collector; bag type static electricity dust collector; double towers desulfurization, etc.), it can realize automatic fuel feeding, automatic ash removing. 


Boiler Application

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


Boiler Feature

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.
