On the selection of the mesh size for pipeline flame arrestor filters
Thread Content
The device has been experiencing problems since the flame arrester filter was replaced in the furnace; the pressure drop has also increased frequently, severely affecting normal operation. I’m not sure what considerations are involved in choosing the mesh size for a flame arrester filter What is an appropriate pressure difference before and after the flame arrester?
This needs to be determined based on the fuel gas pressure required by your furnace, as well as various parameters of your fuel! It makes no sense to just say things out of thin air
Our company uses fire arrestor filters with a mesh size of 300 mesh and a pressure difference of 0.02 MPa.
Depending on the medium quality of the gas, the required gas flow rate and the area of the filter are determined; we use filters with a precision of over 200 mesh
We recycle a portion of the desulfurization dry gas; several dedicated burners often get clogged in the flame arrestors due to poor quality, so we switch to backup burners, remove them for cleaning. If the pressure difference is too high, removing and cleaning it can still solve the problem; it mainly depends on the quality of the gas
May I ask where the flame arrester is installed? What is a medium? What is the caliber?
I would like to ask what is the purpose of installing a flame arrester on the fuel pipeline of a converter? Our furnace uses natural gas along with recycled exhaust gas, and it is not equipped with a flame arrester.
The fire arrestor can be switched for cleaning on a regular basis
What pressure difference is required to remove it for cleaning?
