【 摘 要 】

New reagent composition with optimal phosphate:thermal polymer ratio has been developed and studied for steam-and-condensate channel protection and its corrosion prevention as well as for on-line washing to remove old silicate deposits formations. Optimal dosage and water-chemistry conditions for a medium pressure steam boiler with specified quality of feed water have been selected. The causes of silicate deposits in medium pressure waste-heat boiler have been analyzed. The reagent efficiency has been evaluated while industrial applications.
