Coal-Fueled Diesel Engines - sae

The extensive German development of the use of pulverized coal in diesels during the period 1930 to 1944 demonstrated that coal-fueled diesels can be a practical heat engine. Although the German development used dry pulverized coal as a fuel, it now appears that beneficiated coal-water slurries will be a more practical and economical form of fuel.

Coal - Coal types | Britannica

Coal - Coal - Coal types: Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water (or wind activity) or of minerals such as pyrite and marcasite that formed in place (authigenic). Some formed in living plant tissues, and others formed later during peat formation or coalification.
