  • 專業解析

    循環流化床鍋爐(Circulating Fluidized Bed Boiler, CFB鍋爐)是一種高效清潔的燃燒技術設備,其核心原理是通過高速氣流使燃料顆粒在爐膛内處于懸浮流動狀态(即“流态化”),并利用氣固分離器将未燃盡的顆粒回收至爐膛循環燃燒。其工作過程包含以下關鍵環節:

    1. 流态化燃燒

      燃料(煤、生物質等)與惰性床料(如砂礫)混合後從爐膛底部送入,高壓一次風從布風闆噴入,使混合物形成類似流體的沸騰狀态。燃料在850–900℃的低溫燃燒環境下與空氣充分混合燃燒,有效抑制氮氧化物(NOₓ)的生成。

    2. 顆粒循環系統

      煙氣攜帶未燃盡顆粒上升至爐膛出口,經旋風分離器進行氣固分離。分離後的固體顆粒通過返料器重新注入爐膛底部,形成循環燃燒。此設計顯著延長了燃料停留時間,使燃燒效率提升至95%以上,并適應高灰分、低熱值的劣質燃料。

    3. 污染控制優勢

      爐内可直接添加石灰石等脫硫劑,與燃燒生成的二氧化硫(SO₂)發生反應實現原位脫硫,脫硫率可達90%。低溫燃燒特性同時降低了熱力型NOₓ的生成,無需額外脫硝裝置即可滿足環保排放标準。

    工業應用場景

    該技術廣泛應用于燃煤電廠、城市垃圾焚燒、生物質發電等領域。例如中國自主研發的600MW超臨界CFB鍋爐,通過提高蒸汽參數(壓力25.4MPa/溫度571℃)進一步降低煤耗,成為高硫煤地區的主力機組。國際能源署(IEA)報告指出,CFB鍋爐在燃用高水分褐煤時仍能保持穩定燃燒,其燃料靈活性顯著優于傳統煤粉爐。
