The classification and application of ash water dispersant were introduced.In view of the serious scaling of equipment internal components and pipelines in one coal gasification plant,which seriously affected the safe,efficient and stable operation of the gasification plant over a long period of time,the scale inhibitor and dispersant was independently developed,and its detection indexes and methods were introduced,including solid content,pH,density,scale inhibition rate,phosphorus content,high-temperature scale inhibition rate,dispersion and the effect of flocculant residue on the dispersion.By simulating the operating conditions of the system and detecting the scale inhibition rate and other key indicators after the high-temperature treatment,the ash water dispersant suitable for the ash water system could be effectively selected to alleviate the scale formation of the system and improve the operating stability of the gasification plant.
