Converter inlet and outlet
Thread Content
What equipment is installed at the inlet and outlet of the converter? Should it be installed before the catalyst or after the catalyst is installed?
I don’t understand your true intention; all equipment and fittings must be installed before the catalyst is added, and the pipes need to be purged and verified to be airtight
What the original poster is asking about is probably the installation of the internal components of the converter – there are inlet distributors and outlet collectors, which are installed after the catalyst has been placed in place
Inside the furnace, refractory balls should be installed at both the inlet and outlet. Outside the furnace, adsorbers, heat exchangers, separators, etc. should be installed depending on the specific circumstances
The inlet of the converter (i.e., the upper part of the furnace, where there is usually also a manhole) is equipped with a gas distributor. This distributor is generally simple, though it can also be somewhat more complex; its purpose is to ensure that the gas enters the converter in a uniform manner. After the gas enters, ceramic balls are placed there, with a stainless steel mesh beneath them. Further down lies the catalyst (in some systems, a protective layer is installed first before the catalyst). Below that again is a stainless steel mesh, followed by ceramic balls, and at the bottom is the outlet. A gas collector is installed at the outlet, and there is also a discharge port on the lower side.
The inlet usually consists of a simple distributor, while the outlet must have a layer of ceramic balls for support as well as a gas collector. Your question isn’t clear, so everyone is just guessing in their answers, which doesn’t yield good results. It’s recommended that the original poster provide more details about what they actually want
