摘要
济钢对副产煤气加热炉高效燃烧控制系统进行改造 ,煤气混合系统通过控制焦、高、转炉煤气的比例和压力 ,保证了混合煤气的热值和压力稳定 ;加热炉DCS系统通过控制加热炉废气中残氧量 ,调节空燃比 ,使燃烧达到最佳状态 ,提高了炉内钢坯的加热质量 。
The high efficiency burning control system of reheating furnace with by product gas was improved in Jigang. By controlling the proportion and pressure among the coke oven gas, blast furnace gas and converter gas the calorific value and stable pressure of mixing gas can be ensured. Through controlling remaining oxygen quantity in flue gas of reheating furnace and adjusting the ratio between air and combustion gas in DCS system of reheating furnace the combustion can be up to optimum condition, the aims of increasing heating quality of slab, saving of energy and protecting environment are reached.
