Abstract The anti-scaling process for conveying ash water of steam powder plant is characterized by that before the ash water is conveyed, the ash water is treated, at inlet plate of ash pump a softening pool is set, the furnace smoke drawn from outlet of induced draught fan of the boiler is undergond the processes of washing with water to removed dust, cooling and mixing with air, then blown into the softening pool, when the ash water is flowed through the softening pool, it can be neutralized by mixed furnace smoke, and its pH value is reduced to 8.5-9.2 from 11-12, and the Ca(OH2) being in the ash water can be completely formed into CaCO3, and precipitated, then the softened ash water can be conveyed into ash storage field by means of ash pump.
