Abstract

A system and a method for measuring an ash content and a calorific value of a coal are provided. The system comprises: at least two dual-energy gamma ray transmission measuring devices and a computing device, in which at least one first dual-energy gamma ray transmission measuring device is disposed before an inlet of a coal combustion apparatus for measuring a first attenuation coefficient of a gamma ray from the at least one first dual-energy gamma ray transmission measuring device with regard to the coal; at least one second dual-energy gamma ray transmission measuring device is disposed after an outlet of the coal combustion apparatus for measuring a second attenuation coefficient of a gamma ray from the at least one second dual-energy gamma ray transmission measuring device with regard to a coal ash; and the computing device is configured to compute the ash content and the calorific value of the coal.
