High Pressure Customized Hot Water CFB Boiler for Power Station
▷ CFB Boiler Product Introduction
- Circulating fluidized bed boiler (CFB) is a clean combustion
technique with high efficiency and low pollution.
- Internationally, this technology has been widely used in power
plant boilers, industrial boilers, waste disposal and other fields,
and has been developed to large circulating fluidized bed boilers
of several hundred thousand kilowatts.Domestic research,
development and application in this area also gradually rise, there
are hundreds of circulating fluidized bed boiler into operation or
in the manufacturing.
- The next few years will be an important period of rapid development
- CFB (circulating fluidized bed) in the bubbling bed boiler is
developed on the basis of fluidized bed, so some theories and
concepts of bubbling bed can be used in circulating fluidized bed
- But there are big differences.
- Early circulating fluidized bed boiler fluidization rate is
relatively high, so called rapid circulation circulating bed
boiler.The basic theory of fast bed can also be used for
circulating fluidized bed boilers.The basic theory of bubbling bed
and fast bed has been studied for a long time and formed a certain
- In order to understand the principle of circulating fluidized bed,
it is necessary to understand the theory of bubbling bed and fast
bed and the dynamic characteristics, combustion characteristics and
heat transfer characteristics of materials in various states from
bubbling bed to turbulent bed to fast bed.
▷ CFB Boiler Technical Features
1.Auxiliary fuel economizer
Molecular structure of hydrocarbons by the fuel economizer
processing, change, increase the distance between the molecules,
the increase in the number of small molecular fuel viscosity
decreased, the result of the fuel oil before burning atomization,
refined, to improve greatly, spray into the combustion chamber
internal are fully under the condition of low oxygen combustion,
thus the blast volume of combustion equipment can reduce 15% to
20%, avoid to take away the heat in the flue, flue temperature drop
5 ℃ to 10 ℃.After the fuel of the combustion equipment is processed
by energy saver, it can save oil from 4.87% to 6.10% due to the
improvement of combustion efficiency. Besides, it can be clearly
seen that the flame is bright and dazzling, black smoke disappears,
and the furnace is clear and transparent.Completely remove the
coking phenomenon of the combustion tip and prevent recoking.The
phenomenon of slag accumulation on furnace wall due to insufficient
combustion of fuel can be eliminated, and the effect of
environmental protection and energy saving can be achieved.The
pollution to the air caused by waste gas from combustion equipment
is greatly reduced. The harmful components such as carbon monoxide
(CO), nitrogen oxides (NOx) and hydrocarbon (HC) are greatly
reduced, and the emission of harmful waste gas is reduced by more
than 50%.Meanwhile, the dust content in waste gas can be reduced by
30%-40%.Location: between the pump and the combustion chamber and
nozzle, the environment temperature should not exceed 360 ℃.
2.An energy saving device for a condensing gas boiler is installed
on the upper wall.
The exhaust of gas-fired boiler contains up to 18% steam, which
contains a large amount of latent heat which is not utilized. The
exhaust temperature is high and the obvious heat loss is great.The
burning of natural gas still emits nitrogen oxides, small amounts
of sulfur dioxide and other pollutants.Reduce fuel consumption is
the best way to reduce costs, condensing type gas boiler
