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 of CFB.
• 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 boiler.
• 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 theory.
• 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
