摘要
以某电厂已完成低氮燃烧技术改造的330 MW机组锅炉为研究对象,建立锅炉全尺寸三维模型,采用数值模拟方式获得锅炉冷、热态速度场,温度场及还原性气体的分布规律,并进行性能评价测试试验。结合模拟试验及测试结果进行分析,认为水冷壁近壁区域发生高硫腐蚀的可能性较大。评估结果可为锅炉水冷壁硫腐蚀防治提供参考。
Take a 330 MW unit boiler with low-NOx, combustion technical transformation in some power plant as an example, the three-dimensional model of the full-scale boiler was established. The distribution of cold, hot velocity field, temperature field and product concentration field of the boiler were obtained by numerical simulation, and the performance evaluation test was done at the same time. The simulation results and the test results were combined to evaluate the safety of the heating surface of the water wall in the boiler reduction zone, which provided a reference for effective guidance on the prevention and control of sulfur corrosion in the plant.
