Experiments were conducted to investigate the influence of additives CaO

Fe2O3 and Al2O3 on bed sintering

while waste salty liquids are treated in fluidized bed with sand or coal ash as bed material. The results show that CaO and Fe2O3 can solve successfully bed sintering problems

provided Na2CO3 is formed in sand or coal ash bed

however

Al2O3 can cause serious bed sintering at bed temperature. If NaCl is formed in the sand bed

Al2O3 can solve successfully the bed sintering

CaO and Fe2O3 have some effect on preventing bed from sintering

but these two additives can’t solve the problem completely. If NaCl is formed in coal ash bed

CaO and Fe2O3 can solve successfully the bed sintering

however

Al2O3 can cause bad bed sintering. These results provide the base for the design and operation of fluidized bed incinerator for treating waste salty liquids.
