摘　　要：介绍了硫酸系统转化工序配置的开工炉系统及使用中存在的问题,开工炉系统以轻柴油为燃料,在使用过程中存在排放尾气冒黑烟和氮氧化物浓度高、开工炉换热器因急冷急热和热膨胀导致开裂泄漏、现场SO_(2)低空污染等问题。通过采用低氮燃烧技术及对换热器进行改造,很好地解决了设备故障和环保问题。The startup furnace system configured for the conversion process of the sulphuric acid system and the problems in use are introduced.The startup furnace system uses light diesel oil as fuel,and there are problems such as black smoke and high concentration of nitrogen oxides,cracking and leakage of the startup furnace heat exchanger due to thermal expansion of rapid cooling and heating,and low-level pollution of SO_(2) on site.By adopting low nitrogen combustion technology and reforming the heat exchanger’s thermal expansion problem,the equipment failure and environmental protection problems are well solved.
