“…Our research group and colleagues have developed a portable XRF analyzer. [6][7][8] This analyzer consists of a 109 Cd source with 10 mCi, proportional chamber (U max = 1260 V), 256 channel analyzer, and related digital and analogue electronics including microprocessor. This analyzer enables direct determination of ash content in coal samples and is specifically designed for use by end-users such as coal mines and thermal power plants.…”

“…The determination of coal ash content using XRF technique is based on measuring the intensity of non‐burning chemical elements within the coal samples, along with detecting scattered radiation, both coherent and incoherent. In our research work, 5,6 we proposed that the ash content of coal sample can be determined using the following regression equation:

A_{Ash} = a_{0} + a_{1} I_{1} + a_{2} I_{2} + a_{3} I_{3} + \dots + a_{i} I_{i}

“…Conventional chemical analysis used to determine coal quality involves complex sequential procedures that are time‐consuming. Accordingly, there is an increasing need for simple and rapid methods to determine coal quality, specifically for online technology control in power plants 5–8 . In addition, coal properties such as gross calorific value, moisture, and ash content, which have a significant impact on combustion and environmental performance, often form the basis for sales contracts between coal‐producing companies and coal‐fired power plants, as well as other users.…”

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.
