The Design and Experimental Study on the Lance of the Cement Industry Flue Gas Denitration Technology
The lance is the key equipment of SNCR flue gas denitrification technology injection system on the new dry process cement production line.The atomizing effects of reducing agent will directly influence the result of flue gas denitration. In this paper, there are the structure design and experimental analysis on denitration lance.The results show that the lance can ensure the average diameter of atomized particles is from 50 to 55um,uniformly degree is above 80%, and visual distance of atomized ammonia is above 4 meters.It has been applied in a new dry process cement production line of daily 5kt SNCR flue gas denitration project, reaching above 70% of denitration efficiency. These results are valuable for similar new dry cement clinker production line of SNCR denitration Technology.
