Turbulent fluidized bed(TFB) gasification incinerator has a "variable cross-section" structure

which adopts a turbulent-bed boiler that processes organic waste in a combination of staged feeding

staged gasification

and staged combustion.However

whether the carbon content in fly ash

particle size distribution of fly ash

and mineral composition of fly ash and ash are different from other furnace types remains to be studied.This article takes a TFB gasification incinerator in Vietnam as a case.The full-automatic industrial analyzer

Malvern laser particle size analyzer

and X-ray fluorescence spectrometer were used to analyze the composition

particle size

and elemental composition of the incineration fly ash

as well as the metal oxides enrichment characteristics of the ash components along the incinerator.The results show that

the TFB gasification incinerator has sufficient combustion and the carbon content in fly ash is almost zero.The particle size of fly ash is mostly less than 100 μm.The main components of the incineration ash are SiO_2

CaO and Al_2O_3.The mass percentage of Cl increases along the fly ash path

ranging from 40% to 70%;the mass percentage of most metal oxides increases along the fly ash path.The research can provide a reasonable utilization method for ash and slag in TFB gasification incinerators and corresponding basis for process improvement.
