摘　　要：从研究天然气锅炉中碳黑生成、辐射换热和NOx排放相互关系的角度出发,设计并制作了一套采用傅立叶变换红外光谱仪(Fourier Transform Infrared Spectroscopy,FTIR)作为测量仪器的试验台,整个试验台由三大部分组成:加热器、燃烧器和燃烧室。试验台能够实现包括不同的预混度和不同的炉膛热环境在内的多种工况,通过调试,证实了不同的预混度对火焰形状和火焰温度有很大影响,今后的FTIR测量试验将进一步考察不同的预混度和不同的炉膛热环境对碳黑生成量、辐射换热量和NOx生成量的影响。In order to investigate the correlation of soot formation, radiation heat transfer and NOx emission, a test-bed based on Fourier Transform Infrared Spectroscopy （FTIR） had been designed and constructed. The test-bed is consist of three parts, heater, burner and firebox. The test-bed can implement multi-condition including different premixed degrees and different furnace heat environment. It is tested through the debugging that different premixed degrees have a large impact on flame shape and flame temperature, consequently arouse obvious change on soot formation, radiation heat transfer and NO. emission.
