LEL alarm detection in exhaust pipelines
Thread Content
The concentration of combustible gases in the pipes used for exhaust gas treatment is unstable, fluctuating from time to time; there is a risk of explosion when these gases pass through the booster fans. Are there any instruments installed in these pipes to monitor the concentration of combustible gases in real time? If such instruments are in use, I would appreciate it if you could recommend relevant brands or provide information on them. Thank you very much!
There must be such a gauge. But another factor in combustion and explosion is oxygen monitoring; it is also necessary to monitor the oxygen level inside the pipeline.
Oxygen does not need to be monitored; exhaust gas is essentially air, a mixture of various components. Under normal conditions, the concentration of flammable gases is well below their lower explosive limit.
Does that mean it’s equivalent to measuring the total amount of VOCs in exhaust gases? One can seek out such analyzers from manufacturers of environmental protection analyzers. If it is necessary to determine the composition of specific flammable gases, chromatography must be used, as only chromatography has the ability to separate the components.
The probe can be installed inside the pipeline. You can get in touch with Meisuan.
LEL detection is required, but information on the components of the exhaust gases is needed; in one project, it was specified that T90 should be less than 5S
Hello, may I ask which detection principle was ultimately chosen for your LEL analyzer?
