摘　　要：针对广东某电厂锅炉过热器段严重结焦的现状,采用FLUENT数值模拟和现场实验的方法进行研究,通过对燃烧的煤种、脱硫剂的投用等方面进行分析,认为脱硫剂的大量连续使用和燃用劣质煤是造成过热器段严重结渣的原因,从而提出减弱结焦的对策,使锅炉结焦现象得到一定缓解。Because of the seriously high-tempetature superheeaters＇coking problem of a boiler in a Guangdong Power plant, the methods of numerical simulation and experiment is adapoted.Based on the analysis of the kinds of coal and the use of desulfurization, the coking problem was found to be caused by the largely and continuously using of desulfurization and burning the low-quality coal.In order to solve above problem, correspomding countermeasures are proposed.
