CEMENT KILN FUEL TREATMENT – SCB International

Low sulfur coal is more costly to use compared with high sulfur coal. In order to comply with EPA limits cement kilns must either use a low sulfur coal at an increased cost or install a sulfur scrubber at the back end of the kiln similar to a coal fired power plant. The capex for a sulfur scrubber can be 20 – 30 million dollars.

Cement Kilns: Precalciner kilns

Precalciner cement kilns. As with conventional suspension preheater kilns, the gases leaving the top of the preheater are used for drying raw materials. Some heat is still wasted, because rawmills tend to run intermittently, since they are always designed with "overtaking capacity" to avoid restricting the output of the kiln.

Cement Wikipedia

Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and byproducts with recoverable calorific value can be used as fuels in a cement kiln (referred to as coprocessing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifiions.
