中文摘要	低质量流速垂直管屏技术的核心为Benson内螺纹管。分析了Benson管的基本原理,并对低质量流速垂直管屏技术的应用进行了探讨。低质量流速垂直管屏能够产生自然循环特性,在满足较低质量流速的同时保证锅炉的安全运行。因此低质量流速垂直管屏技术有优势,尤其是在强制循环的煤粉炉和必须采用垂直管的超临界循环流化床锅炉中,Benson管可以减小蒸汽温度偏差,并降低水冷壁流动阻力,可以保证水冷壁更安全,其性能优于光管和普通内螺纹管。低质量流速垂直管屏技术在我国姚孟电厂1号机组的改造工程和波兰超临界循环流化床中均有应用。; The key issues of low mass flow-speed vertical tube-platen technology lies in its inner threaded Benson tubes. The authors have analyzed the basic principle of Benson tubes and explored the application of the above-mentioned technology. The low mass flow-speed vertical tube platen features natural circulation characteristics, guaranteeing a safe operation of boilers while simultaneously meeting comparatively low mass flow-speed requirements. Hence, the low mass flow-speed vertical tube platen technology has its own technical edge, especially for forced circulation pulverized coal-fired boilers and supercritical circulating fluidized bed ones which must adopt low mass flow-speed vertical tubes. The inner threaded tubes can reduce steam temperature deviation and flow resistance in water-cooled walls and secure a safer operation of the latter.
