Gas sampling methods [Request for help]
Thread Content
Since I’m a student, I don’t know much about the products manufactured by companies. I would like to ask everyone here: we want to analyze the composition of the gas coming out of the furnace, so gas sampling is necessary. In companies, how is this sampling point set up? For example, where should the sampling point be located, what methods and equipment are used for sampling, and how is the sampling point installed? The temperature of the flue gas is around 500 degrees. Thank you all for your attention!
A student from Southwest Jiaotong University? Since we’re both studying in Chengdu, I’ll give a brief answer. The gas in the furnace needs to be discharged through gas pipelines, so the sampling port is connected to these pipelines. Of course, before sampling, the sample gas must be depressurized, dehumidified, cooled, and filtered for purification, and specialized purification devices are used for this purpose. When sampling, it is possible to decide whether to use a cylinder for sampling or a bladder (sampling bag), depending on the pressure conditions at the sampling point.
It’s not that school. The boss asked me to check it, and since I have no experience, I came here to ask for help. Thank you!
