【Abstract】 Limestone can be fully calcined and desulfurized in the temperature range of 850-900℃. The combustion temperature in the furnace of circulating fluidized bed boiler is consistent with the desulfurization temperature of limestone, and the desulfurization reaction can be formed in the furnace to achieve the purpose of cheap desulfurization.Desulfurization reaction in circulating fluidized bed boiler is related to bed temperature control, limestone particle size,limestone feeding uniformity, reaction time and other factors. The influencing factors of desulfurization efficiency in the furnace of circulating fluidized bed boiler is analyzed, and discusses the key technologies to improve the desulfurization efficiency in the furnace.更多还原
