What is one primary advantage of corrugated furnaces in terms of structural integrity?

One primary advantage of corrugated furnaces is that they compensate for thermal expansion, which significantly reduces stress on the structure. As the furnace operates, the materials are subjected to high temperatures, causing them to expand. The corrugated design allows for expansion and contraction without causing damage or excessive stress on the furnace structure, thus enhancing its durability and lifespan. This ability to accommodate changes in size due to temperature fluctuations is a crucial factor in maintaining the integrity and operational efficiency of the furnace over time.

In contrast, while lighter construction materials might ease installation, they do not inherently address the issues of thermal dynamics. Similarly, the reduction of insulation needs or improved maintenance accessibility are beneficial features of some furnace designs but are not directly related to structural integrity as influenced by thermal expansion.
