DZL series biomass boiler is a horizontal three-way water fire tube
Smoke gas flue process:
Arrange the threaded pipe in the drum, on both sides have the water
wall tube, front and back arch with a new type of energy-saving
furnace arch, the use of light small scale chain grate is more
conducive to the combustion of biomass fuels, with a blower,
induced draft fan for mechanical ventilation, and equipped with a
slag machine to achieve automatic slag. The fuel from the coal
bucket fell to the grate, enter into the furnace for combustion,
the flame after the back arch refraction upward through the body
both sides burning chamber turn to the front smoke box, and then by
the front smoke box to the threaded pipe in inside of the drum,
after through the back smoke box into the economizer, and then by
the induced draft fan pump the smoke into the atmosphere through
the chimney flue .
1. By pulling the partial ascension pipe on both sides of the heads
into the furnace, and then lead into drum side’s bottom and
supplementing with the bottom of the drum to form the roof heating
surface, the new furnace structure has successfully solved the
bottom of the drum directly by the high temperature flame
radiation, to avoid the "drum package" defects.
2. Two wings smoke flue’s design,tom make the smoke flow into front
smoke box smoothly and the same tube temperature as before to avoid
the temperature stress and produce tube plate cracks.
3. The drum with a single return thread pipe, to strengthen the
heat transfer effect, while the threaded pipe with self-cleaning
function, to avoid the ash deposits inside the pipe.
4. Boiler front and back arch adopt support the water wall tube as
support ‘s overall casting structure, then the formation of
permanent arch. The back arch is low and long, the exit section is
anti-tilt, the front arch angle 45 °,match the back arch, forming a
clear inverted "α" flame, which is conducive to low-grade coal
combustion and has good coal adaptability.
5. Grate lateral sealing structure design is advanced and
reasonable, avoiding the lateral sealing card grate and the grate
both sides uneven wind to cause the defects of burning out the side
seal. 4t / h and less then 4t boiler adopts side seal cold angle
iron plate structure, above 6t / h boiler adopts contact-type
lateral sealing structure.
6. Under the grate have the independent adjustment wind chamber,
from both sides inlet air; Using new crank arm screw adjusting
structure, so that the air ventilation section ratio reaches 100%,
flexible adjustment, ventilation uniform.Push-pull type gate
segment soot cleaning device, gate segment adopts heat-resisting
cast iron with seal structure, thus effectively preventing
secondary combustion deformation and grate air leakage.

1. What size of fuel should be used?
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%
Coal-fired (biomass) boiler, the combustion mode is layer
combustion. Layer combustion is to 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
