Current status of alternative fuel use in lime kilns
In kraft pulp mills, lime kilns are used to convert lime mud (CaCO 3) to lime (CaO) for reuse in the causticizing plant. This process requires a large amount of heat, which is supplied to the kiln mainly by burning either natural gas or fuel oil. Depending on the kiln design and refractory type and whether it is equipped with product coolers or
