当掌握30万千瓦及大功率的机组时,防止СКД锅炉下辐射区高温腐蚀,是当前的一个迫切任务。为了解决这个问题,曾经对下辐射区水冷壁制定了保护方法,主要是在腐蚀区域内输入水蒸汽流。这个方法在Ириклинскй国家区域发电厂ПК-41-1型锅炉上通过了工业性试验,现时在国家区域发电厂一系列的ТГМП-114型锅炉上推广使用。在腐蚀过程中起决定因素的为紧贴在腐
It is an urgent task to prevent the high temperature corrosion of the radiation area under СКД boiler when it is equipped with 300 MW and high-power generating units. In order to solve this problem, protective methods have been developed for the waterwall of the lower radiating zone, mainly by inputting the water vapor flow in the corroded area. This method passed industrial tests on the ПК-41-1 boiler at the national regional power plant Ириклинскй and is currently being rolled out to a series of ТГМП-114 boilers at the national regional power plant. Corrosion in the process of play a decisive factor in close to rot
