Effects of Coal Oxidation on Calorific Value

Energy Sources Part A Recovery, Utilization, and Environmental Effects, 1999
A brief investigation of the effects of oxidation on the calorific values of three Turkish lignite samples has been made. The lignite samples have been vacuum dried and oxidized in pure oxygen at 35, 45, and 55 C at 100 kPa for 10 days. The calorific values of the oxidized and unoxidized samples have been measured.

Ultra-repeatability measurement of calorific value of coal by NIRS-XRF

Analytical Methods, 2023
An ultra-repeatability measurement technology of coal calorific value combined with near-infrared spectroscopy (NIRS) and X-ray fluorescence (XRF) and a holistic-segment modeling method based on partial least squares (PLS) are proposed.
