摘要为了利用现有的基于CFD的预测方法来评估工业煤火焰中NO_2的产生，首先必须建立所选NO_2模型的置信限。在这项研究中，一个简化的战略NO，预测提出和验证使用测量NO，NO，前体燃烧三种不同的加拿大煤在两个试点规模的设施。验证结果表明，所提出的NO，模型可以提供合理的良好的工程估计NO，HCN和NH3从附近的燃烧器区域的炉膛出口在所有的测试情况下。
Abstract To utilize currently available CFD-based predictive methods to assess NO, production in industrial coal flames, the confidence limits of the chosen NO, model must first be established. In this study, a simplified strategy for NO, prediction is proposed and validated using measurements of NO, and NO, precursors obtained from burning three different Canadian coals in two pilot-scale facilities. Validation results indicate that the proposed NO, model can provide reasonably good engineering estimates of NO, HCN and NH3 from the near burner region to the furnace exit in all test cases.
