    On the use of alternative fuels in rotary kiln burners

    Oct 01, 2015 In the rotary kiln process, the fuel is supplied in a burner at the back-end of the kiln and the aim is hence to create a long flame extending far into the rotary kiln. The flame heats the bed surface by radiative heat transfer from the hot combustion products (soot, coal/char, ash and gases)

    Apr 14, 2006 Various types of alternative fuels can be used in rotary kilns depending on the local supply availability, and each one has a specific influence on the flame pattern. Low calorific value waste fuels must be limited to a small portion of the total heat release as they tend to lower flame temperature, but a compromise can be reached when firing high and low calorific value

    Use of Alternative Fuels in Cement Manufacture:

    Rotary kilns can be either wet process or dry process kilns. Wet process rotary kilns are more energy-intensive and have been rapidly phased out over the past few decades in almost all industrialized countries except the US and the former Soviet Union. In comparison to vertical shaft kilns, rotary kilns consist of a longer and wider drum

    Lime kiln is a rotary combustion kiln where heat transfers from combustion gas to lime particles. Lime kilns are typically 2-4 m in diameter and 50-120 m in length with typical rotational speed of 0.5-1.5 rpm. Lime mud is fed to the kiln from cold end and the kiln slopes slightly, about 1-4 per cent toward the firing end. Lime mud moves slowly
