Tóm tắt

The possibility of controlling the ash content of fuel based on a carbon/oxygen ratio taking into account variable carbon content out of the organic matter was demonstrated. An algorithm was proposed for the determination of the ash content with the use of a pulsed neutron method with the detection of gamma rays from inelastic neutron scattering on the nuclei of carbon, oxygen, and calcium with an instrumental correction for the variable chemical composition of the mineral matter of coals. The procedure was recommended for the operational quality control of coarse dispersed fuel whose chemical composition varies over wide limits.
