limitation of cfbc boiler

Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Technical advantages

Digitized manufacture

  • The laying-off of steel tube adopts CNC 3D laser cutting machine.
  • The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
  • The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

Long life span

  • The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
  • Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
  • Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Less fuel consumption

  • Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
  • Furnace adopts double close line coil, which makes heating surface sufficient.

Technology Overview: Circulating Fluidized-Bed Combusti

Lurgi's CFBC technology is similar to the Lurgi-designed aluminum trihydrate calcining process of which there are 24 units installed or under construction worldwide. Pyropower Corp. is now offering commercial CFBC systems in the U.S. based upon the European experience of Ahlstrom Co., Pyropower's parent company.

Circulating Fluidized Bed Combustion | Газогенераторы МС

Circulating fluidized bed combustion is an exceptionally versatile and environmentally friendly technique for the utility market. The classical CFBC process operates at the higher end of the fluidized bed regime, just lower than the transport phase.

Combustion Characteristics in 2 MWe-Class CFBC KIER Powe

The “flue-gas R&D demonstration plant” built in the Korea Institute of Energy Research (KIER) is the only power plant for research. It is equipped with CFBC boiler burning coal (bituminous coal) by 1.4 ton/h, 2MWe-class power plant system, and flue-gas treatment system.

Restrictions and Limitations for the Design of a Stea

A boiler shutdown will be the consequence. To avoid this risk lower oxygen concentrations at the CC nozzle floor are necessary to ensure a secure operation of the CFBC. The limitation of 57 % flue gas recirculation shows a much lower O2 concentration for the oxidant entering the nozzle floor in comparison to 38 % flue gas recirculation.

Utilization of fly ash coming from a CFBC boiler co-firin

Fly ash coming from a circulating fluidized bed combustion (CFBC) boiler co-firing coal and petroleum coke (CFBC fly ash) is very different from coal ash from traditional pulverized fuel firing due to many differences in their combustion processes, and thus they have different effects on the properties of Portland cement.
