GETABEC CFB Steam Boilers designs and builds green and clear energy plants.


Circulating Fluidized Bed (CFB Series) Combustion technology utilizes the fluidized bed principle in which crushed fuel is injected into the furnace or combustor and the fine combusted particles are elutriated out of the furnace with flue gas. The balance particles are then collected by solid separators and circulated back into the furnace.

  • Volute cyclone separator improve the efficiency of the cyclone separator by 2-5%. Fuel is highly adaptable with high combustion efficiency,

  • Reinjection system utilizes quantitative breeze systems and refined design for reinjecting air distribution system, making boiler running continuously, stable and safe,

  • High efficiency separator system can increase limestone utilization rate in obtaining clean and environmentally friendly combustion,

  • Compact furnace, even temperature field, ample heat exchange and high combustion efficiency,

  • Optimal selection of separator injection angle, increasing separator efficiency as well as anti-abrasion capability,

  • Furnace membrane wall uses bends avoidance structure and are jet plated with anti-abrasion materials, increasing the usable lifespan of membrane wall,

  • Components of the boiler use 3D non-metal expansion joints and metal expansion joints, keep it clean and tidy,

  • Innovative exterior design is aesthetically pleasing as well as practical,


Main Structure and Technical Characteristics

  • Whole membrane wall structure

  • Water-cooled air distribution plate and water-cooled air chamber

  • Volute cyclone separator

  • Non-mechanical self-balancing U-type fly ash return device

  • Embedded bell-type hood

  • Membrane wall bends avoidance structure

  • Low position secondary air

  • Under-bed hot air fluidized ignition


Effective anti-clogging Measures

  • Reasonably allocates the ratio of primary and secondary air, ensures that the primary air volume is higher than the lowest fluidized air-flow, which ensures the furnace fuel is fully fluidized .

  • Evenly distributed hood and selects reasonable wind speed, thereby ensuring that bed materials are fully fluidized .

  • Sufficient safety margin between boiler designed operating temperature and fuel softening temperature

  • Refined design of return flow air distribution system.

  • Return flow utilizes quantitative breeze system to achieve smooth reinjection while controlling temperature of reinjecting materials, thereby ensuring that the circulating system does not clog up.
