|
摘要
电站锅炉炉内温度和气体浓度分布在线测量对于控制优化炉内燃烧过程,提高燃烧效率和减少污染物排放具有重要意义。可调谐二极管激光吸收光谱(tunable diode laser absorption spectroscopy,TDLAS)技术在炉内温度与气体浓度在线测量上具有很大的应用潜力。从市场需求、市场阻碍因素、技术难点及投资回报4个方面对TDLAS在炉内温度与气体浓度测量上的应用进行分析,探讨了其工业应用需要解决的关键问题。总体来看,TDLAS技术的投资成本和维护成本相对较高,国内成功应用案例不多,但仍有较大的发展空间。
On-line measurement of temperature and gas concentration distribution in power plant boilers is of great significance for controlling and optimizing the combustion process, improving the combustion efficiency and reducing the pollutant emissions.Tunable Diode Laser Absorption Spectroscopy(TDLAS) technology has great application prospect for on-line measurement of temperature and gas concentration inside the furnace. Therefore, in this paper, the application of TDLAS technology is analyzed in the aspects of market demand, market obstacles, technical difficulties and economic returns, and then the critical problems to be resolved in industrial applications are explored. Overall, due to the relatively high costs of investment and maintenance, there have been few successful applications of TDLAS technology in China. However, it still has considerable potential for its future development.
