Multi-point sampling plan for denitrification flue gas online monitoring system

At present, most of the denitrification outlet measurements are single-point sampling measurement methods. Due to the special working conditions of the denitrification flue, the local concentration distribution is irregular. Therefore, many online monitoring equipment cannot measure the effective concentration, or change quickly, or the measured value Inaccurate and not representative. .Sampling temperature: .(maximum)
