To reduce variations in particle circulation rate even with a variation in inter-layer height difference at a circulating fluidized bed.SOLUTION: The present invention provides a method for the operation of a circulating fluidizer in which particles move between a first fluidized bed and a second fluidized bed. Into a loop seal provided between the first fluidized bed and the second fluidized bed, introduced is vibrated air by means of a gas feeder, which does not introduce air from outside.SELECTED DRAWING: Figure 4

The invention discloses a clean combustion method for non-premixed combustion, which is characterized in that an MOF (Metal Organic Framework) derived monatomic catalyst, a high-voltage electrostatic field and low-frequency acoustic excitation are deeply fused, a space-time coupled multi-field synergistic environment is formed in a combustion cavity, and atomic-scale dispersed active sites provide ultrahigh intrinsic catalytic activity; the electrostatic field drives soot particles and polar pollutant molecules to directionally migrate and be enriched on the surface of the catalyst, and meanwhile, the interface charge transfer process is enhanced; the acoustic flow field significantly optimizes flow field distribution, continuously updates a gas-solid boundary layer on the surface of the catalyst, and realizes dual reinforcement of mass transfer and reaction kinetics. According to the method, the bottleneck of a traditional single or double-element technology is broken through, the soot removal efficiency is larger than or equal to 99%, the CO removal efficiency is larger than or equal to 95%, the system response time is shortened to the second level, stable and efficient operation can be kept within the wide load range, the inhibition efficiency of soot generated by liquid fuel combustion is 99% or above, and the inhibition efficiency of CO and nitric oxide can reach 99% or above.
