Issues with the linings of the two catalytic converters
Thread Content
The linings of both vessels are single-layer steel fiber reinforced linings without a turtle-shell pattern; the insulation spikes are of type V-100, spaced 100 mm apart, and the lining thickness is 100 mm. Is the lining thickness too thin? Is a spacing of 100 too short? Does it cause severe overall heat loss? Please discuss and, in light of the actual conditions of our factory, determine which one is the most suitable
Judging from the problem, it might be the thickness of the precipitator or the flue liner in the low-temperature section? For regenerators, the thickness is generally 150 mm, with a spacing of 100 mm between insulation spikes; this approach can also be used. It depends on the drawings and specifications. In irregular areas, the spacing can be reduced; for regular areas, I think it’s around 150–200 mm. A closer spacing does affect heat dissipation, but not to a significant extent. Since the concept of lining has changed nowadays, it is necessary to keep the metal temperature above 130 degrees (the dew point temperature varies with the S content). Our view is that using a lining with an appropriate thermal conductivity and high strength is in line with the current principles for selecting linings
