Product Discription
DZH Series Pressure Manual Biomass Hot Water Boiler
DZH series pressure manual biomass hot water boiler is horizontal
tee water pipe and fire tube boiler, and a group of gear fire tube
is arranged. Water-cooled walls are designed on the left and right
sides of the stove. For mechanical ventilation, use a lightweight
mobile grill with a blower and fan. The fuel falls onto the
furnace, for example: After the furnace is completely burned, the
flame enters the boiler wall through the flue gas passage in the
central furnace wall, then re-enters the front smoke box from both
sides of the combustion chamber and then returns to the boiler from
the front smoke box. The pipes from the rear smoke box to the
energy saving and dust collector are sucked into the chimney and
chimney by the exhaust fan and eventually discharged into the
atmosphere.
Product Features
1. Easy installation:
Boilers are usually installed quickly at the factory and are
suitable for transport and field installation. The boiler greatly
reduces the construction cycle and saves installation costs to
ensure timely production.
2. Reliable operation:
The heating surface of the boiler is reasonable. The water
circulation ensures a gentle cooling of the heated surface over
time, thus ensuring safe operation of the boiler.
3. Easy to maintain and maintain:
The steam package of the boiler contains pipes that can be checked
and repaired. The flue gas box in front of the boiler is easy to
open, so that people can control it comfortably and clearly and
provide good conditions for proper operation.
4. Fully burned:
In secondary air and a suitable furnace design, the fuel can
completely burn and emit black smoke.
5. Efficient grate:
The boiler grid is matched with biomass fuel to prevent air
leakage, fuel leakage and uneven ventilation. It is easy to use and
has significant advantages over normal grids.
6. Easy to clean ash:
Installing more than one ash extraction holes in the kettle can
effectively remove the ash over time. It prevents the accumulation
of process ash in the boiler, it also prevents the decrease of the
thermal efficiency caused by the ash accumulation in the boiler and
ensures the stability of the boiler load.

Note: The fuel consumption in the table is calculated on the basis
of the low calorific value of biomass particles 17084KJ/Kg
(4085Kcal/Kg). If the low calorific value of biomass fuel is larger
than that, the corresponding fuel consumption will be more
economical than that in the table.
