Explain Fluidized-Bed Incinerators
-  sand is heated to 800C by oil or gas and blown around (fluidized) by a blower that sends air from bottom upward 
-  heated fluidized sand hits sludge, breaks it apart, and burns it 
-  glass and metals must be removed from refuse to incinerated 
-  able to burn wastes of widely variable moisture and heat content (i.e. paper and wood)
