BURNER BLOCKS WIDE, SHORT-CYCLE KILNS

Technical features

Using burner blocks with narrow discharge points (example d.35 and d.30 mm) can significantly increase burner flame speed. Consequently, the material transiting through the kiln chamber is less affected by flame ‘hot spots’ or temperature variations over the cross-section. In wide-mouthed kilns, using long burner blocks (L= 700/950 mm) with narrow discharge points (d.35/d.30 mm) extends the reach into the middle of the kiln chamber, making firing more homogeneous. These blocks have the effect of increasing the speed of the burner flames and shifting them closer to the center of the kiln chamber. Therefore, burner flame speeds are less affected by chimney fume draft deviation. Using RAY-type blocks in wide-mouthed kins improves firing uniformity: by installing them in the firing zones together with long blocks and blocks for high flame speeds, manufacturers can heat pieces at the sides of the load more effectively. The availability of different lengths and shapes of block adapts the heating effect to differently sized pieces and can accentuate or attenuate localized heating effects. Using the Pump Jet burner in pre-heating prevents defects such as black core, cracking and bursting. Featuring onepiece design and a geometry that prevents excessive heating of the kiln walls, it makes firing more uniform over the cross-section and helps increase production, reduce consumption and lower NOx emissions.
