It has been studied to use low-reactivity petroleum coke and low-grade coal as an energy source. Circulating fluidized bed combustion(CFBC) technology efficiently uses low-reactivity because of enough combustion time. In addition, in-furnace desulfurization is possible by using limestone and CFBC reduces NOx emissions due to low operating temperature. Among the various technologies, Oxy-CFB(Circulating fluidized bed) boiler is recognized as eco-friendly technology because it can collect high concentration CO2, which is a greenhouse gas. Thus, direct desulfurization and recarbonization reaction of 4 different kinds of limestones were investigated by using thermogravimetric analyzer under oxy-CFB boiler conditions. |
