在高炉喷吹煤粉中加入SYP喷煤助燃剂、入炉焦炭表面喷洒TY焦炭钝化剂,改善、提高了高炉入炉原燃料某些热态性能,实现降低入炉干焦比、降低综合燃料比的作用。
SYP pulverized coal combustion improver is injected into blast furnace pulverized coal injection, and TY coke passivation agent is sprayed on the coke surface to improve and improve some thermal performance of raw blast furnace into the furnace, so as to reduce the ratio of dry coke into the furnace and reduce the comprehensive The role of fuel ratio.
