10 Ton/H Steam Output Coal Fired Steam Boiler High Pressure Boiler
DZL series coal fired horizontal type packaged boiler is single
drum longitudinal type with natural circulation, the main
components are installed within the factory. After installing the
large parts, just need to setup pipeline, instrumentation valves,
flue duct, and slag extractor, etc, connect water and electricity
power, and incorporated into the heating network system, then the
boiler could operate.
Advantages of DZL chain grate coal fired boiler
1. The crack of pipes and plates under high temperature can be
prevented by using single backhaul solenoid,arch plate,aerofoil
flue and elastomer shell taking the place of rigid shell.
2. The rational designed circulation loop prevents the base heating
and bubbling. Backwater ejecting can improve the reliability of
circular water,get rid of the pipes slagging and let the stove run
orderly.
3. Good smoke prevention and dust control, the dust is inertial
separated from the gas in the stove.
4. Small stove by optimize design and the price of boiler room can
decrease 30%.
5. Good firing, it can add coal and slag remove automatically,so,it
can save the stoker’s labor.
