My idea is to use a linear sieve to separate the 160μm fraction of the ash and then using pneumatic conveying to transport that ash back to the boiler. The rate at which >160 μm ash is generated is around 10kg/h. From what I read I should use a 2:1 air to material ratio, so I would need a blower with a minimum capacity of 20kg/h= 16,3m3/h.Web
