中文摘要:
      本文分析了加热炉燃烧控制系统的现状,提出了采用高温直插式氧化锆进行残氧量在线检测,并采用带交叉限制和残氧修正功能的燃烧优化控制技术,结果表明,基于残氧在线检测方式的燃烧优化控制技术能够实现空燃比和炉温的在线闭环优化控制,降低燃料消耗和氧化烧损生成。具体将基于残氧在线检测方式的燃烧优化控制软件技术投用于湘钢1#加热炉,能够实现加热炉燃烧过程的优化控制的同时,吨钢煤气消耗降低2.84%,残氧控制降低1.94%,氧化烧损减少0.121%。
英文摘要:
      The status of heating furnace control system were analyzed. It was proposed using high temperature in-line zirconia to detect residue oxygen content, and using combustion optimization control technology with the use of cross restriction and residual oxygen correction function. The results showed that the combustion optimization control technology based on the on-line detection of residual oxygen can realize the on-line closed-loop optimization control of air-fuel ratio and furnace temperature, reduce fuel consumption and Oxidation loss. The residual oxygen online detection method of combustion optimization control software technology investment for 1# heating furnace based on the combustion process of reheating furnace can realize optimization control at the same time, gas consumption reduced 2.84% tons, residual oxygen control is reduced by 1.94%, 0.121% reduction oxidation.
