DHX circulating fluidized bed boiler is based on flow reconfiguration combustion technology research and development, represents the circulating fluidized bed technology trend development direction of products. DHX CFB steam boiler has the advantages of coal saving, electricity saving, low bed pressure operation, low wear, high availability and ultra-low emission of pollutants. In particular, ultra-low emission technologies are more in line with air pollutant emission policies and have strong market competitiveness.

Circulating fluidized bed boiler is a kind of energy – saving circulating fluidized bed boiler. Design, this type of products in the steady state flow reconstruction “under the guidance of advanced design theory, based on the reliability of the water cycle, the furnace structure and high efficient separation and return material transporting material circulation system, and better air distribution, classification of combustion technology, wear seal energy-saving technology and efficient desulfurization denitration of ultra low emission technology in the research, the key techniques such as the implementation, determine reasonable water circulation system and boiler structure, make the boiler coal saving, power saving, operation reliability is high and low pollutant emission technology advantage, make its main performance, technical and economic indicators reached higher level.

DHX CFB Steam Boiler Characteristic

1. Low coal consumption: high efficiency separation + cyclic combustion, combustion efficiency > more than 99%, thermal efficiency BBB>%, coal consumption reduced by more than 3%;
2. Save electricity: flow configuration reconstruction, low bed pressure operation, low power consumption rate, can save more than 20% fan power consumption;
3. Environmental protection low emission: precise low temperature graded combustion and air distribution, SO2 and NOx ultra-low initial emission, superior environmental protection performance;
4. Low wear: low bed pressure operation, low gas flow rate, heating surface near zero wear, low maintenance rate, annual running time > 8000 hours;
5. Good fluidization: patented improved bell hood can solve the problems of ash pouring and fluidization, and ensure the boiler combustion efficiency and low emission;
6. High separation: the use of optimized center cylinder bias type efficient cyclone separator, to ensure efficient separation, efficiency up to 99.6;
7. Tail flue structure: ensure efficient heat transfer on the heating surface of the tail;
8. Sealing design: membrane wall, flue guard plate, steel plate and other structures are fully sealed welding to avoid air leakage and ensure high efficiency operation.

The type boiler product to overcome the normal CFB boiler plant utilization high and wear two difficulties, auxiliary power can be reduced by 20% at least, at the same time, effectively make up for the boiler wear, back to the feeder coking jams, original line of high dust concentration and the difficulty of slag discharge, less than, is the boiler structure more reasonable, more excellent performance, more safety and reliable operation.

The content of harmful gases such as S02 and N0X in the exhaust of DHX CFB steam boiler can be reduced by 80% to 90%.
