An experimental study of sewage sludge incineration.
Sludge incinerated ash has been fired at different temperatures. This material was fired at 1050 degrees C for 3 h and until a peak of 1010 degrees C. After thermal treatment the ash was screened at 200 mesh.The ash was characterized by X-ray fluorescence and trace elements like Cr, Pb, Zn, Cu, and some oxides like quartz(SiO2), Al2O3, P2O5, Fe2O3 were found. Scanning electron microscopy(SEM) has shown one change of particle between 2 microm at 90 microm and apparent porosity, thermal analysis has shown loss of mass and residual decomposition in the TG, DTG and DTA curves.
