GRILLE OF AIR PUMPING RODS FOR SUPPLYING AIR TO THE COMBUSTION CHAMBER, DESIGNED FOR USE IN A REACTOR WITH A FLUID BED AND A REACTOR WITH A FLUID BED Russian patent published in 2021 - IPC F23C10/20 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. A grate (1) of air delivery rods for supplying air to the combustion chamber for use in a reactor (12) with a fluidized bed, while the grate (1) of air delivery rods for supplying air to the combustion chamber contains: at least two main air delivery collector rods (2), in fluid communication with a source of fluidizing gas, a plurality of main air delivery rods (3), which are transverse with respect to the specified main air delivery collector rods (2) and are located on the specified at least two main air delivery collector rods (2) so that the main air delivery collector rods (2) provide support for them, and are in fluid communication with at least two of said main air delivery manifold rods (2), while the main air delivery rods (2) and the main air delivery rods (3) define the ash removal holes in the grate (1) from the air delivery rods, a plurality of fluidization nozzles (4) located on each of the main air delivery rods (3) to provide fluidization in the reactor (12) with a fluidized bed, a number of ash bins (6) located under the ash removal holes, the main air-blowing collector rods (6) are made with the possibility of forming external air-cooled walls for ash bins (6), which are cooled by fluidizing gas under pressure.

EFFECT: improving the collection of ash and non-combustible material in the fluidized bed reactor, uniform distribution of the fluidizing gas flow in the bed.
