Scaling in pipeline is a main problem to influence the hydraulic transport ash system of normal work of power plant,with mixture of water and flue gas to remove scale from pipeline is a simple easy way.

Along with the rapid development of the electric industry and in-depth development of energy-saving work,the function of soot blowing in reducing energy consumption and fouling scaling of the power boiler has been caused more and more attention.

An efficient gray-pipe scale-inhibitor,which is low-phosphorus, non-nitrogenous and good in biodegradability, is synthesized with maleic anhydride monomer.
