Control of ash content in coal from the C/O ratio using pulse neutron source

A method for determination of the ash content in coal in large bulks in one measurement cycle from the ratio of intensities of #betta#-radiation of fast neutron inelastic scattering on nuclei of carbon and oxygen has been considered. The experiments have been conducted using an installation comprising a neutron generator of IGM-4 type on the basis of a neutron tube UNG-1. The #betta#-radiation spectrum has been measured using a pulse analyzer of AI-4096-3M type. It is shown that when the ash content in coal is determined according to the method described, the sensitivity increases. The given method is applicable for coal or metallurgical fuel control in large bulks
