Maritza East lignite coal, described earlier3\*'. FA and BA removed by hydraulic transport (in BD these are also removed by conveyers and dumpers in a dry state) are deposited in ash depositories. Average samples were composed of a large number of single samples (30-70), and were taken at different
Coal being a limited source of energy, extraction of energy from other sources like lignite, coal-refuse, and biomass is being attempted worldwide. The minerals and inorganic elements present in fuel feeds pose different technological and environmental concerns. Lignite ash, refuse ash, and biomass
In order to understand trace element behaviour during combustion of coals from the Greymouth coalfield, combustion tests were performed on three seam composite samples. The major and trace elements from sub-samples of feed coal, bottom ash, fly ash, and flue gas were analysed by different techniques
