3.2.2.6. Estimation of pipelines overhaul life duration at pneumatic conveying of ash and coal dust at TPPs and recommendations on its increase

Dependences for calculating pipelines operation overhaul life of installations for pneumatic transport of ash, coal dust and other fine bulk materials for rectilinear horizontal, inclined and vertical, and also curvilinear sections of pipelines are presented. Calculation dependences are developed by employees of Boiler Plants and Ecology of Power Engineering Department of the Moscow Power Engineering Institute (Technical University). Operation, technological and complex provisions on raise of service life of pneumotransport pipelines are resulted.
