Each type of coal has different composition and properties, which determine the coal rank. One of the new methods for determining the quality of coal is by measuring its capacitance. It is formerly known that the difference in the moisture content of coal can be determined from the difference in its dielectric properties. The purpose of this paper is to characterize the various types of coal based on capacitance measurement. The samples used are Lignite, Sub-bituminous, Bituminous, and Anthracite. The proximate analysis testing was done to determine the content of moisture, volatile matter, ash, and fixed carbon. Capacitance value is measured using 2-channel data acquisition system (DAS) and parallel plate capacitive sensor at frequency 2.5 MHz. The results shows that the capacitance values of each type of coal are different. The capacitance value is affected by moisture content of coal since the moisture content and capacitance value have a linear correlation. And also, the signal characterization using frequency from 1 kHz to 5 MHz was performed to verify whether the frequency used in the DAS is able to characterize coal types.

This investigation was done in the laboratory of college of agricultural engineering sciences – University of Duhok to study some wood-charcoal quality produced from some local wood species in Kurdistan region Iraq. In market, the quality of wood charcoal produced from tree species is varied due to divers’ anatomical structure and carbonizing temperature process. As a consequence, understanding the factors controlling the quality of wood charcoal is an important issue for both producers (sellers) and consumers (buyers). In most charcoal factories, wood charcoal are produced without determining of their quality whereas each quality of wood charcoal has its own properties, price and uses. The quality of charcoal made from some selected local wood species (Quercus aegilops, Salix alba, Malus domestica, and Populus alba) were evaluated. The woods species were collected from Zaxo district of Duhok province and were transformed into wood-charcoal using a steel kiln for pyrolysis. The analysis of physical and chemicals such moisture content percentage [MCP] , volatile matter percentage [VMP] , ash content percentage [ACP] and fixed carbon percentage [FCP], of the produced wood-charcoal were proximately resolved using the (ASTM D3176 – 15) method. The results showed, for the first time on all around the Kurdistan region of Iraq, the quality of wood charcoal produced from these wood species. The highest value off moisture content (2.375%) was with Malus domisteca as compared with Populus alba which was (1.000%), highest volatile matter (21.125%) was with Quercus aegilpops compared with Populus alba (4.125%), high ash content recorded (4.875%) with Quercus aegilpops compared with Salix alba (2.250%) and the fixed carbon was greater value in Populus alba which was (92.125%) compared with Quercus aegilpops (72.875%). In addition, these species present significant divergence in term of good quality of wood charcoal and the (populous alba) gave the superior quality of wood charcoal from the rest wood species. Therefore, the results of this study have a high assessment for managers of Kurdistan governmental and private charcoal factories as a suggestion which wood species is suitable in order to achieve better quality of wood charcoal.
