摘要
在分别介绍了蓄热式燃烧理论和富氧燃烧理论的发展、现状和优缺点的基础上,结合西部某实业有限公司轧钢一厂棒材135 t/h高炉煤气双蓄热加热炉改造场地条件限制且实业公司内部制氧厂制氧机组能力富裕较大的现状,提出了在高炉煤气双蓄热加热炉上应用富氧燃烧来提高加热炉产量的技术方案,通过对影响技术方案的因素、富氧燃烧形式选择以及对加热炉的影响分析技术方案的合理性,并分别从技术可行性、经济可行性、环保可行性三个方面进行了可行性分析,分析了加热炉产量的提升、改造投资的回收、加热炉烟气的减排。分析结果表明现加热炉燃烧系统管道及设备均满足加热炉产量提升的改造需求,经济效益明显,投资回收期较短,加热炉烟气污染物减排效果显著,该技术方案具有一定的实施意义。
Based on the introduction of the development,current situation and advantages and disadvantages of regenerative combustion theory and oxygen-rich combustion theory respectively,combined with the limited site conditions of bar 135/h blast furnace gas double regenerative heating furnace in a steel rolling plant in a west industrial Co.LTD.,and the status quo of the oxygen generating unit of the industrial company's internal oxygen generating plant is relatively rich.A technical scheme of applying oxygen-rich combustion to double regenerative heating furnace of blast furnace gas is proposed to improve the output of the furnace.The rationality of the technical scheme is analyzed through the factors affecting the technical scheme,the selection of oxygen-rich combustion forms and the influence on the heating furnace,and the feasibility analysis is carried out from three aspects:technical feasibility,economic feasibility and environmental feasibility.The increase of output,recovery of renovation investment and emission reduction of flue gas of heating furnace are analyzed.The analysis results show that the pipeline and equipment of the combustion system of the current heating furnace meet the demand of the improvement of the output of he heating furnace,the economic benefits are obvious,the investment payback period is short,and the emission reduction effect of the flue gas of the heating furnace is remarkable.
