Is it necessary to install an online monitor for boiler exhaust gas before the purification system?
Thread Content
75t/h, 3.82Mpa medium-temperature and medium-pressure boiler. In accordance with the requirements of the \"Emission Standards for Air Pollutants from Thermal Power Plants (GB_13223-2011)\\", an online monitor with remote transmission functionality is installed after the exhaust gas dust removal and desulfurization systems ； The local environmental protection agency issued an official document requiring the installation of online monitors in the flues prior to the exhaust gas treatment systems (two sets are needed for each furnace; however, the space in the flues is limited and their length does not meet the installation requirements). I checked the \"Administrative Measures for Automatic Monitoring of Pollution Sources,\" and it only mentions that \"(3) Automatic monitoring equipment shall be installed at discharge outlets that meet the requirements of environmental protection standards.\" Please discuss whether it is necessary to install online monitors before the boiler exhaust gas purification system (at a cost of hundreds of thousands). As the boiler user, after submitting a request to our company’s Safety and Environment Department, the department replied that it would be inconvenient to report the matter to the municipal environmental protection agency. How should we proceed in making a comparison? Thank you!
No, it should be after the exhaust treatment equipment, before emission.
Environmental inspections focus on exhaust gases; what is the purpose of monitoring the data before treatment when the gases have already been treated?
Monitoring the parameters before the purification system is still useful for assessing its efficiency; I think random sampling is sufficient, and there’s no need for an online monitoring system.
As long as the treated flue gas meets the emission standards, that’s enough; the Environmental Protection Department doesn’t care about what happens before treatment
Installing it before flue gas purification provides a head start for adjusting the operation of the boiler and the purification equipment, and it also serves as a basis for determining the removal efficiency of the purification device, such as the desulfurization efficiency. It is necessary to install it. In my personal opinion.
Yes, it is sufficient to conduct random tests to assess the purification efficiency; there is no need to install an online monitoring system. Such a system should be installed after the exhaust gas treatment system to monitor whether the exhaust gas emissions meet the standards.
By installing one set at the front, it’s no longer possible to falsify all the data
