Sampling of particle concentration in flue gas at the inlet of the precipitator
Thread Content
Dear experts: Has your company conducted any off-line sampling and analysis of the particle concentration in the flue gas entering the smoke scrubber, for comparison with the online laser measurements? If so, what kind of sampler do you use?
Online manual sampling is carried out on a monthly basis, and the online particulate matter analysis table is calibrated using the data obtained from these manual samples
Does the outsourced party use the weighing method?
1 For sampling the particle concentration of the flue gas at the inlet of the flue gas boiler, either internal sampling or external sampling can be used. Of the two methods I observed, the external sampling method is relatively simpler. This method draws the flue gas out at a constant rate through a filter cartridge; after sampling for a certain period of time, the amount of catalyst per unit volume is determined. 2. Concentration is determined by weighing. 3. Particle size distribution is obtained using a specialized instrument: the catalyst particles are placed in a dispersing liquid to minimize any agglomeration and ensure that individual particles are formed; the instrument then measures the distribution of particles of different sizes
Which contractor was hired? Could you please provide their contact information? If possible, you can send me the manufacturer’s information and contact details to my email address 985392061@qq.com

There is an SP-20 type flue gas sampler produced by a company in Luoyang; it is controlled by a microcomputer. It was first developed by the Luoyang Research Institute, and its performance is better than that of laser-based models, with no issue of data drift.
