主要介绍了广西百色甘化股份有限公司4号锅炉改造的技术路线、调试状况以及改造效果,讨论了改造技术方案的选择。运行实践表明,改造达到了预期目的,改造后的锅炉燃料适应性好,纯烧煤、纯烧蔗渣以及混烧,均燃烧稳定、性能优良,出力由改造前的最高46t/h超过额定达到57t/h,锅炉热效率由改造前的59.6%提高到89.4%。本次锅炉为糖厂煤粉蔗渣锅炉的技术改造做了有益的探索,其成功经验为改造蔗渣煤粉炉,提高其稳定性和经济性具有一定的借鉴。
This paper mainly introduces the technical route, commissioning status and reformation effect of No. 4 Boiler Reforming Co., Ltd. of Baise Gan Guangxi Co., Ltd., and discusses the options of revamping the technical solutions. The operation practice shows that the reform has achieved the expected goal. The modified boiler fuel has good adaptability. Pure coal, pure bagasse and mixed coal are both stable in combustion and excellent in performance. Output from the highest 46t / h before the transformation reaches 57t / h, boiler thermal efficiency increased from 59.6% before the transformation to 89.4%. The boiler for the sugar refinery bagasse boilers technological innovation made a useful exploration, the successful experience for the transformation of bagasse pulverized coal furnace to improve its stability and economy have some reference.
