Abstract

1204177 Combustion in fluidized beds COAL INDUSTRY (PATENTS) Ltd 1 Oct 1968 [10 Oct 1967 7 June 1968] 46234/67 and 27239/68 Headings C5G and G10A Carbonaceous material is combusted in a fluidized bed of ash particles, having a carbon content of not more than 0.5% at a temperature between 700‹ and 900‹C, calcium carbonate, in the form of limestone or dolomite also being fed to the bed. Preferably the weight of carbonate supplied is between 2 and 14% of that of the carbonaceous material, which is in the form of coal. Both the carbonaceous material and the carbonate are in the size range 0-10 B.S.S. Ferrous oxide may also be introduced into the bed.
