Are there any specific requirements and relevant standards regarding the length of the sampling pipelines in CEMS systems?
Thread Content
Hello everyone. As a newcomer to desulfurization and denitration, I have some questions I would like to ask you all. I am currently working on a desulfurization and denitrification project, and I have a few questions regarding the CEMS system. 1. Are there any length requirements for the sampling pipelines of the CEMS system? Are there any upper or lower limits or something? This relates to the distance between the CEMS chamber and the sampling point. If there is a requirement, why is there such a requirement? What consequences will arise if the requirements are not met? If the length does not meet the requirements (it’s too long), is there any solution? 2. Are there any relevant technical specifications regarding the design of CEMS chambers, the area required, as well as the placement and spacing requirements for cabinets? If not, can we proceed according to the HG/T 20508-2014 Control Room Design Specification? Please, experts, help me out. Thank you all in advance!
There are requirements regarding distance, and the cabin must comply with the JH75 standards.
The pipeline length has the most direct impact on the sampling lag time; it also affects the insulation length. It is best to consult the manufacturer to find out what other effects there may be, as this is related to the specific testing equipment used.
