As discussed in Part 1 (CI, September 2011), internal kiln pressure in a tunnel kiln governs airflow direction and affects temperature uniformity, soaking time, and energy consumption. Management of the kiln pressure profile makes a huge difference in kiln stability.
Figure 1. Kiln temperature data at various locations in the kiln setting. Kilns should be the foundation of the ceramic factory, producing consistent results, creating zero defects and performing efficiently.
