为了提高电厂锅炉煤中Ca组分的自脱硫能力，对烟气进行了喷水增湿脱硫的实验研究。介绍了实验设备、喷嘴结构、测量方法和仪器。研究了喷嘴结构、入液方式和相比对液滴尺寸分布和喷射角等喷雾特性的影响。结果显示了显著的变化，并说明了如何优化喷嘴的设计和操作。
In the present paper, an experimental investigation of the humidifying and desulfuration of flue gas by water spraying is conducted in order to increase the ability of the self-desulfuration efficiency of Ca composition in coal in a power plant boiler. The experimental facility, nozzle structure, measurement method and instruments are introduced. The influence of nozzle structure, the way to enter the liquid and the ratio between phases on the spray characteristics including size distribution of the droplet and spray angle is studied. The results show significant variation and show how to optimize the design and operation of the nozzles.
