摘　　要：利用CFD数值模拟手段对蓄热式天然气烧嘴的几何结构进行改进计算,通过计算对比不同空气进口切向角度以及空气分级比例下的烧嘴NO_(x)理论排放结果,得出最优空气进口角度与分级比例。依此搭建试验平台,进行连续升温排放测试,对数值模拟结果进行验证。The CFD numerical simulation method is used to improve the calculation of the geometric structure of the regenerative natural gas burner.By calculating and comparing the theoretical NO_(x)emission results of the burner under different inlet tangential angles and air classification ratios,the optimal air inlet angle and classification ratio are obtained.Based on this,an experimental platform was built to conduct continuous heating up tests to verify the numerical simulation results.
