But increasingly strict USregulations have led to the use of ammonia DeNOx systems even on FBCs.這項技術使在14001700華氏度（760930攝氏度）的溫度下燃燒，在這個范圍內產生的氮氧化物較傳

6、統(tǒng)的煤粉機組要少。但是日益嚴格的化床燃燒系統(tǒng)中也需要使用。使得氨法脫硝系統(tǒng)在流Units 機組/裝置，單元USRegulation/規(guī)定，準則，DeNOx 脫硝（4）Fluidized-bed combustion evolved from efforts in Germany to control emiss from roastingsulfate ores without the need for external emiscontrols (such as scrubbers-flue gasdesulfurization). The mixing action of the flui

7、dized bed brings the flue gaseso contact wisulfur-absorbing chemical, such as limestone or dolomite. Moren 95% of the sulfur pollutants inthe fuel can be captured inside the boiler by the sorbent. The sorbent also captures some heavy metals,though not as effectively as do the much cooler wet scrubbers on conventionaits.流化床燃燒是從德國發(fā)展起來的，源自一種控制焙燒硫酸礦石排放而無需外部排放控制（例如洗滌塔煙道氣體脫硫）的嘗試。流化床燃燒的混合作用使得煙氣與可吸收硫的化學物質，如石灰石或白云石等進行接觸，煙氣中超過95%的硫化污染物可以通過吸附方式在鍋爐中捕獲。吸附劑同樣捕獲一些重金屬，但是效果遜于傳統(tǒng)機組中溫度更低的濕式洗滌塔。Control控制 / 控制器emis排放；/擴散external 外部；/表面，外國fl
