Abstract：Some kinds of dry fluegas desulfurization technology are introduced and the charcteristics of those is analyzed systematically．Because coal with high calcium and low sulfur content is bumed in most of thermal power plants in Shanghai,a simple flue gas desulfurizatton method is proposed to adopt spray water to humidify a and activate high calcium content coal fly ash for SO2 removal．
