Electrical Hot Water High Pressure CFB Boiler for Industry or Power Station
What is CFB Boiler?
- Quartet plant design and manufacture of a circulating fluidized bed boiler using clean combustion technology, the new boiler with highcombustion effcincy and low pollution of the typical characteristics of learning from the experience of other circulating fluidized bed boilerdesigned on the basis of optimizing.
- The coal adaptability, can be applied to bituminous coal, lignite coal, mixed coal and other different kinds offuel, the combustion efficiency up to 99%, especially combustible fuel with higher sulfur content by adding limestone to the furnace cansignificantly reduce sulfur dioxide emissions, due to low temperature combustion. Nox emissions are significantly reduced, thereby reducing thecorrosion of equipment and flue gas pollution of the environment, the utilization rate of slag, cement, etc,can do the admixture.
- The boiler isanatural cycle. M-type arrangement, the frame supporting hanging structure, using the cycle with a cyclone combustion system, for themembrane wall furnace, superheater from high and low two layout, the middle set spray superheater, the tail of Sec economizer and a secondaryair preheater.
- Boiler according to interior decoration design, operation level elevation of 7 meters, all of the metal framework of the boilerstructure for 7 degree earthquake intensity.
What are the features of CFB Boiler?
| Highest Allowable Outputs • Highest Pressure.
• Highest Temperature.
• Steam Flow (up to 1,000,000 PPH). | Greatest Fuel Flexibility • Best overall solution for high moisture fuels.
• Ability to burn fuels containing mid-level amounts of alkali.
• Proficient at combusting fuels from the extreme low-end to extreme high-end moisture contents. |
| Higher Efficiencies • Lowest excess oxygen required for complete combustion.
• Lowest unburned carbon. | Lowest Uncontrolled Emissions of NOx, SO2, CO, VOC’s and PM. |
What should be focused on CFB Boiler?
- Circulating fluidized bed is of low-temperature combustion, therefore, nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurized during combustion process. Circulating fluidized bed boiler with high desulfurization rate is economical.
- Circulating fluidized bed boiler could adopt various coal types and has high combustion efficiency, which is especially suitable for low quality, low calorific value coal.
