Large central power stations (about 1000 MW electrical) using fluidized bed combustors may be built some day These giants would be fed 240 tons of coallhr (90% C, 10 % H2,), 50% of which would burn within the battery of primary fluidized beds, the other 50% elsewhere in the system. One suggested design would use a battery of 10 fluidized beds, each 20 m long, 4 m wide, and containing solids to a depth of 1 m. Find the rate of reaction within the beds, based on the oxygen used.
