APPARATUS FOR MEASURING AMOUNT OF EMITTED HEAT FROM COAL BY USING RADICAL RAYS

摘要

ethod comprises exposing radioactive rays to coal sample, separately measuring scattered rays and particular X-rays, and calculating a caloric value and a calcareous quantity by corelating the measured value. The equipment includes a head (1) in which coal sample is positioned vertically to a radioactive rays source, an iodic natrium crystal (10) for transfering the scattered radio-active rays to a light, a tube (11) for amplifying the light, and a plate (12) for transducing the amplifyed light to an electrical pulse signal.
