Aiming at the problem of low desulphurization rate of calcium-based additive in chain furnace, the law of dynamic change of composition of mild gas in chain hearth is studied. The effects of additive particle size, adding amount and adding method on the desulfurization rate of various calcium-based additives are studied On the proposed two-stage combustion desulfurization solution to achieve the purpose of simultaneous desulfurization within the coal bed and the combustion chamber, from time to time and space to overcome the two simple and pre-mixed into the furnace or coal-fired direct desulfurization The fundamental flaws of the way, so that the chain furnace combustion desulfurization efficiency increased by 70% to 80%.
