Case sharing of online monitoring and pretreatment systems for kilns, boilers, chimneys and pipeline gases
[Copy link]
The online waste gas monitoring system is mainly used in the gas analysis industry. The working principle is to sample the flue gas or high-temperature and high-humidity gas to be tested on site for cooling, dehumidification, dust filtration, tar filtration treatment and then test. The whole process is automated and does not require human intervention. The online waste gas monitoring system is used in places where the gas to be tested has little dust, high temperature and high humidity. For places with more dust and tar, more tar processors are required.
