One of the key characteristics, affecting intensity of slurry pipelines’ attrition, is the abrasiveness of the transported material. It depends on the content of silicon oxides, a form and fineness of ashes particles. According to input data, it is figured out that different types and grades of coals with different chemical properties, fractional composition and coal fineness were incinerated at different times on HTPP-3. Because of it the attrition is result of different types’ transportation of ashes with various abrasive properties, with various fineness, density and chemical composition. Calculation results of pulp pipelines’ specific attrition at transportation of ash-slag pulp on HTPP-3 are given in this work.
