This ash requires higher initial conveying velocity 1415 ms The initial conveying velocities obtained in the existing systems are lower – about 9 ms Large number of bends in the piping layout from ESP hoppers to Buffer hoppers adds to the problem Separate ash removal system for APH ash will be a better option 16 14 12 10 8 6 4 2
Nov 22 2014 · Pneumatic conveying system of fly ash in a thermal power plant 1 Fly ash is one of the residues generated in combustion and comprises the fine particles that rise with the flue gases Fly ash is generally captured by electrostatic precipitators or other particle filtration equipment
Feb 01 2012 · A conveying system for fly ash must also be designed properly Often times pneumatic conveying systems are used to transfer fly ash from the collection hoppers to the storage silos
pneumatic conveying systems have such test facilities for this purpose If it is required to make a quick check on the potential of an existing system or to provide a check on design proposals there is little information readily available for the engineer to use Pneumatic conveying does not lend itself to simple
For dilutephase conveying values are typically up to about 15 although they can be higher if the pressure gradient is high as with a short pipeline or a high pressure drop For the densephase flow of materials such as fine fly ash and cement values can be in excess of 100 and again higher values can be achieved with a short pipeline or a high pressure drop
