摘要:

马钢7.63 m焦炉采用活性焦脱硫脱硝工艺,副产物用于生产硫铵,可降低投资,且无二次污染。6 m焦炉采用干法脱硫+除尘一体化技术,占地面积小、投资费用低。实践表明,活性焦脱硫脱硝工艺运行成本更低。

关键词: 脱硫脱硝, 7.63 m焦炉, 6 m焦炉, 运行成本

Abstract:

In Masteel,7.63 m coke oven adopts desulfurization and denitrification technology by active coke,in which the by-products can be used to produce ammonium sulfate.This solution can reduce investment and have no secondary pollution.And the 6 m coke oven adopts an integration of dry desulfurization plus dust removal technology,which is characterized with less land occupation,low investment,and no by-products generation such as solid waste.The actual production proved that using active coke has lower operating cost in running the desulfurization and denitrification system.

Key words: DeSOx and DeNOx technology, 7.63 m coke oven, 6 m coke oven, Operating cost
