INFLUENCE OF ASH FRACTIONAL ABRASION HEATING SURFACE POWER BOILERS
This article analyzes the causes abrasion of boiler heating surfaces. The dependence of the dispersion of the abrasive wear of fly ash. With sieve characterizationspecific sampling fly ash was obtained percentages for individual size fractions of ash. According to the abrasiveness of each fraction, ratio of the probability that particles on the pipe and the content of its share of wear was determined in the ash falling on each fraction at different fineness of grinding of coal.
