The lime kiln and causticizing plant form a closed loop. There are 475 rotary kilns in kraft pulp mills globally. In the past fifty years the thermal efficiency of the lime kilns has improved from 23 GJ/tonne to around 7 GJ/tonne. In Canada, the lime kilns process from 115 tonnes CaO/day to 430 tonnes CaO/day. The burners have a thermal rating from

Using the simplest form of hydrocarbon, methane, the basic combustion process is: CH4 + 2 O2 + 7.7 N2 fuel air. CO2 + 2 H2O + 7.7 N2 combustion products. The actual heat released in the kiln is the 'net' heat reflecting the conversion of fuel to CO2 (gas) and water vapor. In the US heat release values are quoted in 'gross' terms ...
