引进赫斯特技术的大型制磷电炉设计运行分析

Analysis of Design and Operation of Large Phosphorus Furnace with Hoechst Technology

分析了昆明三聚磷酸五钠厂引进赫斯特技术的大型制磷电炉运行中出现的问题,并对比赫斯特公司两家同类技术的制磷电炉存在的问题进行分析研究,从中分析引进制磷电炉试车生产中的谜团,提出:电极位置的平衡是制磷电炉熔池理论及所涉及的炉内电流、热量形成、分布合理、均匀的关键,是制磷电炉稳定运行的关键环节。

Issues in the operation of the large phosphorus furnace with Hoechst technology in a sodium tripolyphosphate(STPP) plant in Kunming are analyzed. Issues in the phosphorus furnaces of the same Hoechst technology are analyzed,so as to analyze the difficulties in the commissioning of the phosphorus furnace. It is proposed that the balance of the electrode position is the key of the furnace hearth,and formation and distribution of electric current and heat in the involved furnace,and is a key factor of stable operation of the phosphorus furnace.
