Sealing issue of expansion joints in combustion furnaces~~~~
Thread Content
I would like to ask everyone: A 10mm expansion joint has been installed on a certain furnace; this joint is filled with high-temperature mullite fibers, and the gaps are also sealed using refractory mortar. How thick should this “sealing” refractory mortar be? Are there any relevant standards that explain this? Thank you
Expansion joints are primarily designed based on the expansion rate of refractory materials, and the length of the furnace wall is also a factor to be considered when designing such joints. The fillers used in expansion joints mainly include high-temperature resistant rock wool, etc.
