300,000-4,200,000 KCal/H Natural Gas Diesel Oil Fired Hot Water
Boiler For Central Heating
CWNS type fully automatic fired hot water boiler is a
fast-installed horizontal internal combustion three-pass fire tube
structure. The offset furnace liner wet back layout is adopted, and
the high-temperature flue gas sequentially rushes through the
second and third return flue pipes, and then is discharged into the
atmosphere from the back flue chamber through the chimney. The
boiler is equipped with world-famous burners, adopts advanced
technologies such as automatic combustion ratio adjustment,
automatic feed water adjustment, program start and stop, and
automatic operation, and has automatic protection functions such as
operating water temperature control, over-temperature,
over-pressure flameout, etc. This type of boiler has the
characteristics of compact structure, safety and reliability,
simple operation, rapid installation, low pollution, low noise and
high efficiency. It is widely used in enterprises, hotels,
hospitals, office buildings, civil buildings and other facilities
for industrial steam, life and heating.
Rated power: 0.7-7MW
Calorific value: 60-6 million kcal/h
Rated outlet pressure: normal pressure
Rated outlet temperature: 85℃/60℃
Thermal efficiency ≥98% (with condenser)
Application range: It is widely used in greenhouse agriculture,
animal husbandry, residential areas, schools, hotels, swimming
pools, bathing centers and other industries. It can automatically
heat users or provide bathing water and domestic hot water.
Boiler Specification
Boiler Advantage
1. Boiler proprietary technology
Fully wet-backed back-combustion chamber, the back-combustion
chamber is butt-connected with the rear tube plate, and the boiler
is 99.9% fully butt-welded, with the lowest stress and more
reliable quality.
2. Large diameter corrugated furnace
The boiler combustion chamber is composed of a large-diameter
full-corrugated furnace, with large combustion space, complete fuel
combustion, effective absorption of thermal expansion, and large
radiant heating surface.
3. Sufficient heat
The total heating area of the boiler is sufficient to fully
absorb the effective heat, the exhaust gas temperature is low, the
heat loss is small, the output is sufficient, and the efficiency is
high.
4. Strong thermal load regulation ability
The pot shell has a large diameter, large water capacity, strong
adaptability to load changes, and stable output.
5. Thoroughly solve the problem of hot water boiler supercooling
boiling. The return system of the hot water boiler is
scientifically arranged, which increases the disturbance of the
water side of the heating surface in the high temperature zone,
avoids the phenomenon of subcooling boiling in local areas, and
completely solves the problem of high temperature zone pipes. The
problem of cracks in the plate and tube ends.
6. Multifunctional safety and explosion-proof device The back panel
of the boiler is equipped with an explosion-proof device connected
to the furnace to prevent the high energy generated at the moment
of deflagration in the furnace when the fuel is violently ignited
in the furnace. It can automatically reset, and has a fire sight
glass and maintenance. The function of the channel is to make use
of the adjustment of the combustion flame during operation to
facilitate furnace inspection and maintenance.
7. Convenient maintenance in the boiler. The top of the boiler is
equipped with a manhole, and the middle and lower parts of the
front and rear ends of the boiler are respectively equipped with
unique hand-hole devices, which facilitate the inspection and
cleaning of the equipment in the boiler and the bottom of the
boiler.
8. Unique front and rear smoke box sealing. The smoke box adopts
double-opening smoke box door, which is easy to open, multi-stage
labyrinth seal, special sealing material, good compressibility,
completely block the leakage of smoke, and can be reused.
9. Reliable pressure and temperature protection. Multiple control
protections for boiler pressure and water temperature, as well as
over-smoke temperature protection, ensure the safety of boiler
operation.
10. Leading level of automatic control The boiler controller adopts
Siemens/Delixi electrical components with reliable performance.
There are three types of controllers: ordinary type, Chinese and
English menu type with LCD display, touch screen type with
man-machine dialogue remote control
