摘要:
针对当前火电机组碳排放监测中的NDIR冷干法浓度测量存在取样延时，单点皮托管流速仪测量代表性差，矩阵流量计系统复杂，故障率高，低流速测量精度差等问题，采用TDLAS技术和超声波技术实现烟气二氧化碳浓度和流速同步测量。基于TDLAS原理结合原位方式实现二氧化碳浓度快速测量，基于超声波时差法结合多声道方式实现烟气流速测量，将浓度和流速测量结果传输至碳排放服务器进行排放量计算、存储和传输。该系统在某火电机组进行应用示范，整套设备安装至脱硫后水平烟道处，稳定运行后，采用第三方便携设备对测量结果进行比对测试，浓度测量准确度小于2%，流速测量相对误差小于2%。
Abstract:
In response to the problems of sampling delay in the concentration measurement of NDIR cold drying method，poor representativeness of single point pitot tube flowmeter measurement, complex matrix flowmeter system, high failure rate, and poor accuracy at low flow rate measurement in the current carbon emission measurement of thermal power units，TDLAS technology and ultrasonic technology are adopted to achieve synchronous measurement of flue gas carbon dioxide concentration and flow velocity. The system is based on TDLAS principle combined with in-situ method to achieve rapid measurement of carbon dioxide concentration, and based on ultrasonic time difference method combined with multi-channel mode to achieve flue gas flow velocity measurement. The concentration and flow velocity measurement results are transmitted to the carbon emission server for emission calculation, storage, and transmission. The developed system was applied and demonstrated in a thermal power unit. The entire equipment was installed at the chimney, and after stable operation, a third-party portable device was used to compare and test the measurement results. The concentration measurement accuracy was less than 2%, and the flow rate measurement relative error was less than 2%.
