本文在实验室的高温炉内,研究了含钒铁水炉外脱硫粉剂中,CaF_2、Na_2cO_3、Al、C和Na_2B_4O_7等组分对石灰粉剂脱硫的影响及机理。提出了各组分的适宜添加量和改善脱硫反应动力学条件的实验结果。为选择含钒铁水炉外脱硫粉剂的适宜组成提供依据。
In this paper, the effect and mechanism of CaF_2, Na_2cO_3, Al, C and Na_2B_4O_7 and other components on the desulfurization of lime powder in desulfurization powder containing vanadium-bearing iron-water furnace were studied in laboratory high temperature furnace. Put forward the appropriate amount of each component and improve the desulfurization reaction kinetics conditions of the experimental results. In order to choose the suitable composition of desulphurization powder outside the vanadium-containing molten iron furnace provide the basis.
