2.8.13 Pneumatic Ash Conveying Pipe Line

 

                        The fly ash conveying lines from the fly ash collection chute outlets to the intermediate surge/buffer hoppers or continuous dust separators, and from buffer hoppers to dry ash storage hoppers silos etc. shall be designed to withstand the expected wear from the pneumatic transport of fly ash.

 

                        The piping layout should, within the limitation, of the specifications, reduce to a minimum the expected wear and abrasion.  In general, every effort should be made to utilise straight sections as much as possible.

 

                        All the pipelines and supports shall be capable of withstanding all possible pressure/vacuum and loads that may result during various normal and abnormal conditions of operations.
