Rotary Kiln Gas Consumption

Rotary Kiln Gas Consumption

C. The usable life span of the rotary kiln was rather short compared to the life of the multiple hearth furnace. D. The fuel consumption rate averaged 27,520 kJ/kg (11,830 BTU/lb) for the externally-fired rotary kiln pilot plant. This consumption rate was about twice that of a multiple hearth system. E

    Enter Kiln Fuel Consumption - Cement CO2 Protocol

    The kiln fuel consumption is summarised as energy use in terajoules per year [TJ/yr] in line025 to line028.. Further evaluations of energy use and CO 2 emissions from fuels are provided in the KPI section.. Please also see the Protocol Guidance Document for further guidance on the reporting of fuel energy use and CO 2 emissions (Chapters 3.5, 3.6, 3.7 and 5)

    The rotary kiln system is well suited for converting larger particle sizes and the integration of the cyclone preheater greatly improves specific energy consumption over just a straight kiln. It also reduces the size of the kiln and makes treatment of off gases very simple because the heat is removed prior to treatment
