Method and apparatus for oil shale pollutant sorption/nox reburning multi-pollutant control

A method of decreasing the pollutants produced by the combustion of a primary fuel (coal) by introducing into the combustion chamber 6 oil shale particles when the pollutants produced include at least at least one pollutant selected from a first group consisting of a nitrogen-containing pollutant, sulphuric acid, sulphur trioxide, carbonyl sulphide, carbon disulfide, chlorine, hydroiodic acid, iodine, hydrofluoric acid, fluorine, hydrobromic acid, bromine, phosphoric acid, phosphorous pentoxide and a second group consisting of elemental mercury or mercuric chloride. The oil shale particles combust to produce sorbent particulates and a reductant. Pollutants from the first group are exposed to at least one of the sorbent particulates and the reductant at a temperature ranging from greater than or equal to approximately 450°C to less than approximately 1150°C. Pollutants from the second group are exposed to sorbent particles at a temperature of less than or equal to approximately 200°C.
