Circulating fluidized bed boiler furnace staged combustion system
ActiveCN110836364Bincrease temperatureImprove efficiencyFluidized bed combustionIndirect carbon-dioxide mitigationCombustion systemAir volume
The present invention discloses a circulating fluidized bed boiler furnace segmented combustion system, which is composed of a membrane water-cooled wall, a horizontal air distribution plate at the bottom, and an angled feeding and spreading area at the front wall of the water-cooled wall. Compared with a traditional circulating fluidized bed boiler, after the fuel enters the furnace, it first undergoes a preheating, evaporation, and spreading process, and then falls into the combustion space above the air distribution plate at the bottom of the furnace under the action of gravity for fluidized combustion. For circulating fluidized bed boilers that burn biomass fuels or garbage fuels with high moisture content, this system can fully dry, burn, and burn out fuels with high moisture content and difficult ignition, so that the agglomerated fuel can be fully spread in the furnace combustion space, improve combustion uniformity, and reduce air distribution plate temperature deviation, thereby effectively solving the problem of air distribution plate coking, improving boiler combustion efficiency, and improving economy. At the same time, the system can control the combustion situation in the furnace, control the flue gas temperature level and oxygen content by adjusting the air volume at various locations, thereby reducing nitrogen oxide emissions.
