                SNCR+SCR混合煙氣脫硝技術√

                      SNCR+SCR混合煙氣脫硝技術發揮了SNCR工藝投資省、SCR工藝效率高的優勢,將SNCR工藝的〗還原劑噴入爐膛,利用逃逸氨進行催化反應,技術與SCR工藝△結合起來,進一步脫◎除NOx。混合脫硝工藝以尿素為吸收劑,是爐內一種特殊@的SNCR工藝與一種簡潔的後用處端SCR脫硝反應器◥有效結合。具有◥催化劑用量◢少、脫硝你們離開吧效率高、運行費用低等特點。

                 

                技術特點:

                相對於SCR工程造價有所㊣降低;

                脫硝效率高;

                催化劑用量少,回收量少;

                較SCR反應器小,具有更好╳的空間適用性;

                脫硝系統阻爆炸竟然使得周圍力小,引♂風機出力小;

                SO2/SO3 轉化所引起的腐蝕和★ABS阻『塞問題小;

                減少SCR催化劑對煤的〓敏感度;

                可以安全地使用尿素作為還原劑,無需熱解系統;

                分步實施,分期到位。
