This paper analyzes the natural desulfurization process taking place in coal-fired units using Greek lignite. The dry scrubbing capability of Greek lignite appears to be extremely high under special conditions, which can make it possible for the units to operate within the legislative limits of sulfur dioxide (SO2) emissions. According to this study on several lignite-fired power stations in northern Greece, it was found that sulfur oxide emissions depend on coal rank, sulfur content, and calorific value. On the other hand, SO2 emission is inversely proportional to the parameter gammaCO2(max), which is equal to the maximum carbon dioxide (CO2) content by volume of dry flue gas under stoichiometric combustion. The desulfurization efficiency is positively correlated to the molar ratio of decomposed calcium carbonate to sulfur and negatively correlated to the free calcium oxide content of fly ash.
本文分析了使用希腊褐煤的燃煤机组中的自然脱硫过程。在特殊条件下，希腊褐煤的干法脱硫能力似乎非常高，这使得机组有可能在二氧化硫（SO2）排放的立法限制内运行。根据对希腊北部几个褐煤火力发电站的这项研究，发现硫氧化物的排放取决于煤的等级、硫含量和热值。另一方面，SO2 的排放量与参数 γCO2(max) 成反比，γCO2(max) 等于化学计量燃烧下干烟道气中最大二氧化碳（CO2）体积含量。脱硫效率与分解碳酸钙与硫的摩尔比成正比，与粉煤灰中游离氧化钙的含量成反比。
