PURPOSE:To provide a firing potash manure under a combustion heat in a furnace by a method wherein potash or the like is mixed with ash discharged from a combustion furnace to make some particles and feed them into a combustion furnace. CONSTITUTION:Ash collected by a dust collector 3 is mixed with solution of potash such as KOH or the like and other elements of small volume in a mixing machine 6 and thereafter they are fed into a fertilizer dryer 7. The mixture is made as particles having a diameter of about 1-3mm.phi and then dried. Subsequently, the particles are fed into a fluidized combustion furnace 2. Within the furnace, the particles may act as a sludge fluidized medium in place of medium sand, the sludge is made as a fluidized condition to improve an effect of combustion of the sludge and at the same time the sludges are ignited under a combustion heat, resulting in producing some particulated firing potash manure with an advanced solubility of citric acid.
