Abstract

Direct coal injection to a gas turbine is expected as an advanced high efficiency power generation technology. In this case, feed coal must be ash-free and alkaline and alkaline earth metal-free to prevent erosion and corrosion of turbine blade. In this study, ion exchange treatment of coal was investigated to remove Na, K, Ca and Mg.
