1-15ton output coal/wood /biomass fired steam boiler for AAC
Autoclaved Concrete Block plant
DZH type active grate biomass steam boiler has a wide range of fuel
sources. It is a renewable green energy source. It contains almost
no sulfur and less ash. Its growth process can absorb all the CO2
generated by the combustion process and achieve zero CO2 emission.
Biomass energy will gradually replace coal and become one of the
main energy sources. Biomass fuels include straw, wood shoots,
bamboo wood processing waste, grain shell skin, fruit shells, sugar
residue, oil residue, and so on.Compared with coal-fired boilers,
biomass fuels are less expensive and significantly reduce operating
costs.

Structure
The fuel enters the furnace and burns on the grate. The flue gas
from the production enters the convection tube bundle on both wings
along the bottom of the boiler barrel through the smoke outlet on
the middle partition wall, enters the threaded smoke pipe through
the front smoke box, passes through the dust collector, and is
pumped and discharged into the atmosphere through the chimney by
the induced draft fan.

Remarks: The fuel consumption in above table are counted the low
calorific value of biomass pellet as 17084 KJ/Kg (4085Kcal/Kg), if
the low calorific value of actual biomass fuels is bigger than
this, the corresponding fuel consumption will more save than above
data in table.
Technical characteristics
1. 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.
2. 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.
3. 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.
4. Safe Operation: DZH series is equipped with automatic water-level control,
automatic pressure control, automatic interlock chain stop
protection, free settable working.
