From coal to natural gas: Its impact on kiln production ...

19/4/2013  Abstract: In the North American energy market, natural gas prices have been gradually decreasing during the past several years, primarily due to advances in shale gas extraction techniques. The availability of cheaper natural gas (NG), while seen as an attractive short-term fuel switching option, is viewed with caution by most cement plants due to long-term procurement concerns.
