摘　　要：以一步法热法磷酸生产余热回收改造为研究对象,利用建立的考虑热法磷酸生产过程推动力和节能潜力的评价体系对改造前后的生产系统进行了能量利用、经济效果和环境影响对比分析,证明了该项余热回收技术改造具有可行性。An evaluation method, which considered the process driving force and the energy-saving potential of phosphorousacid production by BEP Burning ElementalPhosphorus), was built in thispaper. Anevaluation was ( done on the waste heat recovery of one-step phosphorous acid production by BEP, in which the change of energy utilization, economic results and environment effects were considered. The results proved that this energy-saving retrofit was feasible.
