This relates to a process for burning coal wherein the emission of SOx or the emission of SOx and NOx are minimized. The process comprises (a) providing a coal containing at least twice as much organic calcium than sulfur; (b) burning the coal at a temperature greater than about 1200 DEG C under reducing conditions; (c) separating the solids effluents from the gaseous effluents; and (d) burning the gaseous effluents at a temperature from about 1000 DEG C to 1500 DEG C under oxidizing conditions. |
