Abstract

173,504. Praceiq, E. Bouchard-. Dec. 24, 1920, [Convention date].. Composition fuel.-Fuel for use in powder form is obtained by mixing finely divided fuels having calcareous ash, for example most peats, with fuels having silico-aluminous ash such as most coals and certain lignites, in such proportions that after combustion the ashes are utilizable after refining as hydraulic cements. Iron oxide is an essential constituent of the mixture.
