我厂对还原罐的使用寿命进行了专门研究,选用低硫原煤直接加热还原罐,原煤的含硫量控制在1%以下,这样可减少硫对还原罐的腐蚀。还原温度控制在1160℃至1200℃范围内。根据还原罐的受力情况,还作了还原罐几何形状的受力分析。由于罐内抽成3Pa 以内的真空,还原罐圆
I plant on the life of the reduction tank conducted a special study, the selection of low-sulfur raw coal directly heated reduction tank, the sulfur content of raw coal control in less than 1%, so as to reduce sulfur corrosion of the reduction tank. Reduction temperature control in the 1160 ℃ to 1200 ℃ range. According to the reduction of the tank stress, but also made reduction geometry analysis of the tank. As the tank pumping into 3Pa within the vacuum reduction tank round
