摘要

对某台600MW机组锅炉烟气脱硝SCR装置的性能和催化剂特性进行了评估。结果表明

机组满负荷时脱硝装置的最高脱硝效率仅有65%

飞灰的硫酸钙及其它物质造成催化剂堵塞阻碍NOx和NH3向活性颗粒的扩散

是导致催化剂活性下降

脱硝效率降低的主要原因。对此

可通过化学清洗及再生以恢复催化剂活性。

Abstract

By means of site tests and laboratory analysis

performance of the SCR equipment and the catalyst characteristic for boiler of a 600 MW unit were evaluated.Results show that the maximum denitration efficiency of the SCR equipment is only about 65% when the unit is running under full load.The main reason for this decrease is that the dispersion of NOx and NH3 to the active particle is impeded due to the catalyst deactivation because of the calcium sulfate and other compounds in fly ash.Thus

via chemical cleaning and regeneration

the activity of the catalyst can be recovered.
