近几年来,随着化学工业的发展,不少化工生产采用了新设备、新工艺和新技术,许多老的设备、工艺也正在更新改造,这些新情况、新问题带来了一些不安全因素,火灾屡次发生,特别是化工生产的关键部位——反应釜爆炸燃烧事故不断发生。反虚釜一般具有很高的温度和压力,而参加反应的物料大都属于易燃、易爆、易腐蚀、剧毒物品,所以一旦发生事故,往往造成重大伤亡和损失。从近几年发生的13起较典型的化工企业反应釜火灾案例看,引起火灾的原因、反应 In recent years, with the development of the chemical industry, many new technologies, new processes and new technologies have been adopted in chemical production. Many old equipment and processes are being updated. These new and emerging problems have brought about some unsafe factors , Fires occur frequently, especially the key part of chemical production - reactor explosion and burning accidents continue to occur. The retort kettle generally has very high temperature and pressure. Most of the materials involved in the reaction are flammable, explosive, corrosive and highly toxic. Therefore, in the event of an accident, heavy casualties and losses are often caused. From 13 cases that occurred in recent years, typical chemical reactors fire cases, the cause of the fire reaction
