Abstract

The three-step of MSWI fly ash washing process, to remove chloride from fly ash as much as possible, were investigated. The results show that with the increase of L/S, the release of chloride and sulphate both increased at the first step, but the effect of second and third washing step decreased for chloride, while the effect for sulphate increased. The suitable washing condition happened with a L/S ratio of 5 and 2 minutes of washing, considering the two economic factors (water consumption and economical factor).
