General introduction
DZL series horizontal structure one drum water fire tube coal &
biomass fuel manual fixed grate boiler are energy-saving,
eco-friendly and prominent advantages comparing with other boiler
structures.
1. DZL chain grate boiler is a kind of horizontal three-return fire
and water tube composite boiler.
2. In the boiler drum there is a thread smoke tube and left and
right side of the furnace have light pipe cold water thickness.
3. It adopts light chain grate, which can realize the mechanical
stoking together with air blower and induced draft fan for
mechanical ventilation.
4. Besides, it has slag extractor for realizing the automatic
de-slagging, and its furnace adopts new-type energy-saving arch.
5. The fuel is put on the grate from the coal bucket, and then goes
into the furnace for firing.
Boiler control operation system
1. Adopting automatic screw feeding, with reasonable second air
technology and half gasification structure.
helping fuel combust completely, the thermal efficiency can reach
more than 90%. Stable flame, producing steam cautiously.
2. Primordial dust emissions density is low:The volume of the
coal-fired steam boiler is large and there is a dust separation
device, so the primordial dust emissions density will be controlled
much lower than the standard allowed.
3. Control system: Installing microcomputer to operate with
one-button, people just set the process, and it can work
automatically during the operating time. Once any abnormal
situation to happen, stopping automatically with sound-light alarm,
and pointing to the failure code, so it saves time to maintain.
4. Our protected device is safe and reliable. Selecting superior
pressure controller, safety valve, low water alarm, Over pressure
alarm, over-temperature alarm, in order to make boilers operate
safely.
5. Heating fast:There are many spiral gas tubes in the boiler and
almost half of the coal fired steam boiler shell can be heated, so
the temperature can up soon.
6. It is simple to clean slag only after burning completing.
Boiler advantages
Low running cost, safe and reliable
Short installation time, low installation cost
The output power remain constant high quality of steam
The boiler is heating up quickly and have high heat efficiency
Low original dust concentration,environmental protection and energy
conservation
Small size appearance, low investment in boiler room
