Characterization of some Nigerian coal for effective power generation and industrial utility

Large numbers of trace elements occur in coals used for coal power plants combustion. In order to assess the environmental impact fuel cycle, and ash samples need be analyzed a number toxic radioactive elements. Six from Ridi-Awe Lafia (Nasarawa State), Garin Maiganga (Gombe state) Nigeria deposit were collected. The subjected gross calorific value determination, X-ray diffraction spectrometry, fluorescence spectroscopy determine it suitability generation industrial utility. Base on laboratory analysis results, is observed that values Awe are 29.18MJ/kg, 30.79MJ/kg. 26.10MJ/kg, 25.10MJ/kg 25.50MJ/kg, 24.21MJ/kg respectively. XRF results indicates presence transition metals some element but void such as Arsenic, tin tungsten which makes health hazard friendly. proximate revealed % content Awe, Lafia, 87, 62, 79. moisture 8.7, 16.3, 8.3 volatile matter 4.3, 21.7 12.7 whereas fixed carbon 78.3,55.8 71.1 However, terms rank, bituminous high C, Subbituminous A, hence reactivity maturity decrease (A) ˂ (L) (M). result shows nitrogen dangerous
