燃烧室进口高温高压状态下一氧化碳排放特性研究
An Investigation on Carbon Monoxide Emission of Testing Combustor with High Inlet Pressure and Temperature
-
摘要: 对装有双旋流空气雾化喷嘴的试验燃烧室在宽广进口总温、进口总压范围以及燃烧室油气比范围内的一氧化碳排放特性进行了试验研究。取得了燃烧室在高温高压状态下工作时一氧化碳排放特性结果。并且根据已有一氧化碳排放指数经验模型,计算了相同工况下该试验燃烧室一氧化碳排放量。Abstract: The emission characteristics of carbon monoxide were investigated in the testing sector of a combustor with double swirlers.The test condition covered wide range of inlet pressure,inlet temperature and fuel-air ratio,including the highest pressure up to 4 MPa.The carbon monoxide emission data were obtained from the test.The test data are consistent with the results calculated from the Lefebvre's empirical model,based on available data.
