Oil Fired Hot Water Boiler with Automatic Control and Three Return Trip (Power: 35MW--14MW)
General introduction
WNS type oil fired hot water boiler is currently China's advanced environmental protection product.
It is a horizontal internal combustion three-return shell full-speed steam or hot water boiler with wet back and corrugated furnace construction, as well as threaded tube heat transfer.
The boiler consists of a boiler main engine, a steam-water system, imported brand-name burners, and control cabinets.
The operation control of the oil fired hot water boiler is divided into manual control and fully automatic control.
Technical Features
1. Full fuel combustion
The oil fired hot water boiler is designed with a fully wet return combustion chamber. The
combustion chamber consists of a large diameter full corrugated
furnace with a large space to ensure full combustion of the fuel.
2. High thermal efficiency
The oil fired hot water boiler has a large radiant heating surface that absorbs heat
sufficiently. The special winding structure can effectively reduce
the exhaust gas temperature, reduce heat loss and improve the
thermal efficiency of the boiler.
3. Strong adjustment ability
The oil fired hot water boiler is designed with a large-capacity casing, which increases the
capacity of the water and improves the adaptability of the boiler
to load changes. The reliability of the equipment completely solves
the problem of the boiler being flooded by the hot water boiler.
3. Reasonably arrange the hot water boiler return water system,
increase the interference of the hot surface in the
high-temperature zone, avoid the local area supercooling, and solve
the crack problem of the tube sheet. High-temperature zone.
4. The oil fired hot water boiler is designed with an explosion-proof device that is connected to
the furnace to prevent the fuel from colliding with the furnace
when the furnace is seriously exploded.
5. Easy to maintain and maintain
The boiler design has a sight glass and a detection channel, which
can monitor the operation of the equipment at any time, adjust the
combustion flame in time, and at the same time, the furnace is easy
to inspect and maintain.
6. Unique seal design
Double-opening cigarette case, easy to open, special for sealing
material, good compressibility, and completely blocked smoke
leakage can be reused.
7. Multiple guards
The boiler design has multiple guards that can alarm for
overpressure, high temperature, leakage, water shortage, leakage,
etc., and has an automatic shutdown function to ensure the safe
operation of the boiler.
8. Advanced automatic control technology
Fully automatic control, simple operation interface. At the same
time, it has protection functions such as overload, abnormal
flameout, air pressure and gas leakage. The port used for remote
monitoring is reserved.
