Figure-6: Calciners general classification,CRH, Turna nad Bodvou (SK) - A TEC - Innovative,,This was realised by moving the existing meal inlets to the riser duct of about 8 – 10 m. As the kiln is equipped with an extended kiln riser duct (without tertiary air) it is possible to fire a significant amount of fuel in this kiln riser duct. Now about 20 % of the total fuel as SAF with main burner quality can be fired. Additionally the current bypass system has been equipped with a,Preheater – Dalmia GSB,The riser duct recycles heated air from lower cyclone stages and within the kiln itself, thus improving the thermal efficiency and reducing fuel costs. Dalmia GSB´s based anti-coating castables are highly resistant to abrasion and provide a maximum service temperature of 1600℃. Solutions for Upper /111658903 kiln-burning-systems - SlideShare,31/07/2014· Furthermore, burning some fuel in the riser duct reduces the fuel requirement and thermal loading in the kiln, thus improving the kiln refractory life. In this kiln system, the excess air in the burning zone is increased, and the additional oxygen in the riser duct allows additional fuel to be burnt there. This can be an ideal place to burn some waste fuel such as waste oils or tires. The,Coating formation in Kiln Inlet - Page 1 of 3,11/06/2008· Coating formation in Kiln Inlet .
