【摘要】 根据SO₂和NO_x以及烟尘分别在不同光谱波段具有吸收和散射特性的特点,对同一测量光谱分别用差分吸收光谱法（DOAS）和多波长消光法进行数据处理,并辅之互相关法,可同时监测SO₂、NO_x和烟尘的浓度、烟尘粒度以及总排放量。基于这些方法,研制了一套直接在线烟气连续监测系统（CEMS）。在一采暖锅炉上成功地进行了不同运行工况下现场较长时间连续监测。更多还原

【Abstract】 According to SO₂ and NO_x and dust absorption and seattering characteristics in different spectral bands,the sys- tem use the differential absorption spectrometry（DOAS）and multi-wavelength extinction method and related method to data process the same measurement spectrum,at the same time can measure SO₂,NO_x and dust concentrations and dust particle size and the total emissions.Based on these methods,developed a set of on-line smoke and dust monitoring system （CEMS）.The system was applied to a heating boiler successfully in the different operating conditions at a longer time continuous monitoring.更多还原
