Experimental study of ash wear of heat exchange surfaces of the boiler

Annotation. Based on comparative experiments, the value of the reduction in wear was obtained for transversely washed tube bundles with different geometries, as well as for pipes and tube boards of tubular air heaters. The dependence of the wear of tube bundles and the distribution of wear along a number of relative steps is established. The dependence of the amount of wear reduction on the diameter of the pipes is established. The distribution of wear along the length of the pipe tube air heater with an upward movement is obtained.
