摘要
本文结合螺旋管圈水冷壁的结构特点,分析变压运行超超临界锅炉螺旋管圈水冷壁运行安全性的主要影响因素,包括管内水动力不稳定性、传热恶化、炉膛内烟温偏差以及制造安装缺陷等。
Combined with structure features of helical tubes circle of water-wall, the article analyzed the main influencing factors on operation safety for ultra-supercritical boiler operating pressure mode, including the tube hydrodynamic water power instability, the heat transfer deterioration, the smoke temperature deviation in the furnace, as well as the defects of manufacture and installation.
