When the vapor/ coal ratio is increased, the REs of Cd, Co, Cu, Ni in the low temperature coke from bag filter are increased at first than decreased.

Through the adoption of measures of addition of a coke filter, replacement of catalysts, and improvement of the steam distributors, not only the normal production indications are ensured, but also the resistance in the shift converters is markedly reduced, giving satisfactory results.

通过采取增设焦炭过滤器、更换触媒、改进蒸汽分布器等一系列措施，不仅保证了正常的生产指标，而且还使变换炉的阻力有了明显下降，取得了满意的效果。
