Boiler Feature
Advanced Structure
DZL steam 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 coal steam 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 industrial steam boiler 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.
Economic operation
This series of industrial steam boilers can operate normally under 70%~100% load. Under operating conditions, the parameters include feed water temperature, steam pressure, fuel consumption, fuel type, steam temperature, boiler evaporation, steel consumption, efficiency and exhaust gas temperature. (For specific values, see the boiler specification table in the general drawing).
Delivery standards
(1) This series of steam boilers below 6 tons are delivered as a whole package, and the main engine and combustion equipment of boilers larger than 6 tons are delivered separately and assembled on site.
(2) Blowers, induced draft fans, slag removers, dust collectors, economizers, electric control consoles, platform escalators, valves, instruments, flue ducts, etc. shall be delivered according to the drawings or according to the contract.

FAQ of coal fired boiler
1.. What are the differences between vertical type boiler and horizontal type boiler with the same capacity?
1. Structure of vertical boiler is compact, occupy a limited area,
2. Convenient on installation and removal.
3. Low cost and investment on capital construction. Steam exhausted fast and sufficient.
1. The combustion space of horizontal is big, fuel can be burned completed.
2. The thermal efficiency is higher than the vertical boiler,
3. Horizontal type: less thermal loss, stronger output, and higher steam quality.
2. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?
Size requirement of coal:6-25mm
Size requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)
Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%
3. What is the size of furnace door and blower hopper?
Size of furnace door:
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500
4. What is the combustion mode of coal/biomass fired boiler?
The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
