Lightweight aggregate from fly ash and sewage sludge |
| abstract |
A method is shown for producing a lightweight aggregate by treating fly ash and sewage sludge. The fly ash and sewage sludge are mixed together (30) and then agglomerated into pellets (12) with or without the use of a binder. The pellets may be coated (14) and then are dried (16). The dried pellets are introduced into a rotary kiln (18 or 38) in a direction that is co-current with the flow of fuel and air through the kiln. The pellets in the kiln will be indurated and will experience complete calcination as well as varying degrees of pyrolizing and sintering. The product of the kiln is a nodular material having a low density but with a hard and porous structure. The product of the kiln is fed to a cooler (24 or 44). The fly ash sewage sludge mixture has a significant fuel value that is usable in the kiln. Furthermore, the fuel value available in the kiln off-gas may be used for drying the materials. |
