摘要:
针对当前烟气提水系统仅通过出口水浓度进行测量、接触式测量抗干扰性能低、单点测量代表性不足以及无法对提水系统进行精确调控等问题，提出了一种基于TDLAS技术结合原位插入测量方式的解决方案，实现了对烟气提水入口和出口水蒸气浓度的非接触式多点同步在线监测。系统主要由分析仪和激光原位测量探头组成，将烟气提水入口和出口烟道各划分为四个区域，每个区域安装一个激光原位测量探头，分析仪中的激光分束后传输至各原位测量探头，完成测量后数据传回分析仪进行浓度反演，从而实现对烟气提水系统的监测。通过在电厂某机组实证应用，证实了该系统的适用性，显著提升烟道水浓度测量的代表性，为烟气提水工艺的智能调控提供了更精确的实时数据支持。
Abstract:
In response to the current problems of the flue gas water extraction system, such as measurement only based on the water concentration at the outlet, low anti-interference performance of contact measurement, insufficient representativeness of single-point measurement, and inability to precisely control the water extraction system, a solution based on TDLAS technology combined with in-situ insertion measurement is proposed. This solution enables non-contact multi-point synchronous online monitoring of water vapor concentration at the inlet and outlet of the flue gas water extraction system. The system mainly consists of an analyzer and in-situ measurement probes. The flue gas water extraction inlet and outlet ducts are each divided into four regions, with one in-situ measurement probe installed in each region. The laser in the analyzer is split and transmitted to each in-situ measurement probe for measurement. After the measurement, the data is sent back to the analyzer for concentration inversion, thereby achieving monitoring of the flue gas water extraction system. Through practical application in a certain unit of a power plant, the applicability of the system has been verified, significantly improving the representativeness of water concentration measurement in the flue duct, and providing more accurate real-time data support for the intelligent control of the flue gas water extraction process.
