QUESTION NO.1 Large central power stations (1000 MW electrical) using fluidized bed combustors may be built some day. These giants would be fed 240 tons of coal/h (90% C, 10% Hz), 50%. of which would burn within the battery of primary fluidized beds, the other 50% elsewhere in the sysyem. One suggested design would use a battery of 10 fluidized beds, cach 20 m long, 4 m wide, and containing solids to a depth of Im. Find the rate of reaction within the beds, based on the oxygen used, in terms of kmol, m' of solid and hours.
