Abstract
A combustor air bar grid for use within a fluidized bed reactor includes at least two main air collector bars in fluid communication with a source of fluidizing gas, a plurality of primary air bars that are transversal to the main air collector bars and arranged on the at least two main air collector bars such that the main air collector bars support them, and in fluid communication to at least two of the main air collector bars. The main air collector bars and the primary air bars define ash removal openings in the air bar grid and a plurality of fluidized nozzles are arranged to each of the primary air bars for fluidizing the bed reactor. A fluidized bed reactor includes such a combustor air bar grid.
Claims26
A combustor air bar grid for use within a fluidized bed reactor, the combustor air bar grid comprising:
- at least two main air collector bars in fluid communication with a source of fluidizing gas;
- a plurality of primary air bars that are transverse to the main air collector bars and arranged on the at least two main air collector bars such that the main air collector bars support the plurality of primary air bars, the plurality of primary air bars being in fluid communication with at least two of the main air collector bars, and the main air collector bars and the primary air bars defining ash removal openings in the air bar grid;
- a plurality of fluidizing nozzles arranged to each of the primary air bars for fluidizing the bed reactor;
- and
- a number of ash hoppers arranged beneath the ash removal openings,
- wherein the main air collector bars are configured to form external air-cooled walls for the ash hoppers that are cooled with the fluidizing gas.
A fluidized bed reactor comprising a furnace having a combustor air bar grid, the combustor air bar grid comprising:
- at least two main air collector bars in fluid communication with a source of fluidizing gas;
- a plurality of primary air bars that are transverse to the main air collector bars and arranged on the at least two main air collector bars such that the main air collector bars support the plurality of primary air bars, the plurality of primary air bars being in fluid communication with at least two of the main air collector bars, and the main air collector bars and the primary air bars defining ash removal openings in the air bar grid;
- a plurality of fluidizing nozzles arranged to each of the primary air bars for fluidizing the bed reactor;
- and
- a number of ash hoppers arranged beneath the ash removal openings,
- wherein the main air collector bars are configured to form external air-cooled walls for the ash hoppers that are cooled with the pressurized fluidizing gas.
