The basic data on erosion in pipelines at pneumatic conveying of ash, coal dust, cement, coke, sand and other fine bulk erosive materials are presented. Major factors are revealed and estimation of their influence on erosion in pneumotransport pipelines is executed. Dependences for calculating erosion in rectilinear (horizontal, inclined and vertical) and curvilinear sections of pipelines are resulted. Error estimation at calculating erosion in pipelines at pneumatic conveying of fine bulk erosive materials is given. The developed dependences are results of experimental and analytical researches carried out by employees of Informational and Analytical Center “Ecology in Power Engineering” and Boiler Plants and Ecology of Power Engineering Department of Moscow Power Engineering Institute (Technical University).
