Q1:Large central power stations (1000 MW electrical using fluidized bed combustors may be built some day. These giants would be fed 240 tons of coalh (90%C, 10% H:, 50%of which would bum 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 1m. Find the rate of reaction within the beds, based on the oxygen used, in terms of kmol, m' of solid and hours.
