Monitoring gas temperatures throughout the newly lined areas during the dryout heating process is critical for several reasons. Proper temperature control is essential to ensure the refractory material cures correctly, achieving optimal bond strength and durability. High temperatures can lead to thermal shock or cracking, while low temperatures may prevent the full curing of the refractory, resulting in inadequate performance.

By focusing on gas temperatures, operators can maintain the required thermal profile and ensure that the refractory material is subjected to suitable conditions to facilitate the drying process. This will help in preventing failures and extending the lifespan of the lining.

While monitoring other factors like gas pressure, air quality, and humidity levels may also be relevant in certain contexts, they do not directly influence the efficacy of the dryout process as significantly as gas temperatures do in this specific scenario. Maintaining the correct temperature environment is paramount for ensuring that the refractory lining performs effectively once it is put into service.
