Abstract

The review provides an overview and description of the results obtained from our coal studies conducted over the past two decades. It places specific emphasis on crucial parameters, including the ash content and calorific value of lignite, which is the main energy source in Mongolia. Through the research, we observed that the ash content of coal can be estimated by analyzing the concentrations of key chemical elements, including Ca, Fe, and Sr. The results of ash content obtained from the x‐ray fluorescence analysis are consistent with the outcomes of chemical analysis. Furthermore, we established an inverse linear correlation between the calorific value of coal and its ash content. Building upon this correlation, we have proposed a method that allows for the direct determination of coal calorific value without relying on calorimetric measurements.

x射线荧光在蒙古褐煤中的应用综述

这篇综述概述和描述了我们在过去二十年中进行的煤炭研究取得的结果。它特别强调关键参数，包括褐煤的灰分含量和热值，褐煤是蒙古的主要能源。通过研究，我们发现可以通过分析煤中Ca、Fe、sr等关键化学元素的浓度来估算煤的灰分含量，x射线荧光分析得到的灰分含量结果与化学分析结果一致。此外，我们还建立了煤的热值与其灰分含量之间的反线性关系。基于这种相关性，我们提出了一种方法，可以直接确定煤的热值，而不依赖于量热测量。

期刊介绍： X-Ray Spectrometry is devoted to the rapid publication of papers dealing with the theory and application of x-ray spectrometry using electron, x-ray photon, proton, γ and γ-x sources. Covering advances in techniques, methods and equipment, this established journal provides the ideal platform for the discussion of more sophisticated X-ray analytical methods. Both wavelength and energy dispersion systems are covered together with a range of data handling methods, from the most simple to very sophisticated software programs. Papers dealing with the application of x-ray spectrometric methods for structural analysis are also featured as well as applications papers covering a wide range of areas such as environmental analysis and monitoring, art and archaelogical studies, mineralogy, forensics, geology, surface science and materials analysis, biomedical and pharmaceutical applications.
