选择性非催化还原脱硝温度窗口内尿素液滴的蒸发和转化特性
Evaporation and Conversion Characterizations of Urea-water-solution Droplets Within the Temperature Window for SNCR DeNOx
摘要
Abstract
This study focused on the evaporation and conversion process of urea aqueous solution droplet and the process characterization in the temperature range for selective non-catalytic reduction (SNCR). An in-situ observation system was built to study the evaporation and conversion of urea aqueous solution droplet. Based on the analysis of droplet photo, the droplet diameter variation can be quantified. The evaporation and conversion process of urea aqueous solution droplet can be divided into two stages. The first stage (water evaporation) is consistent with the simple substance water and the second stage is basically the same characteristics as evaporation and decomposition of pure urea particle. Increase in evaporation temperature or solution concentration shortens the characteristic time of the first stage and promotes the microexplosion in the second stage. Change in initial droplet size has little influence on the characteristics of the evaporation process in the first stage.关键词
