管式炉排烟尾气余热利用技术的开发与应用

摘要

针对传统管式炉排烟尾气余热未进行回收利用的问题，设计开发了管式炉排烟尾气余热回收利用新技术，通过对管式炉和硫酸铵生产系统部分设备的工艺改造，在确保硫酸铵产品完全满足质量技术标准的前提下，实现了管式炉排烟尾气余热的综合利用，降低了工序能耗，改善了环境。%With regard to the problem in conventional tube furnace that waste heat in tail gas is not recovered for reuse,a new technology is developed to recover and reuse the waste heat of tube furnace tail gas.Under the precondition that the quality of ammonium sulfate meets technical requirement, through process modification of tube furnace and equipment of ammonium sulfate production system, the waste heat of tube furnace tail gas is comprehensively used, process energy consumption is re-duced,and environmental condition is improved.
