Waste Materials That Can Be Utilised As A Fuel Source For Cement Kilns
Liquid And Solid Special Wastes
The easiest of these to handle are the liquid wastes since they can be received in a lorry, analysed, blended and injected into a kiln. Handling waste solids and semi-solids are a different matter. Depending upon the type of kiln, the waste solids can be pneumatically injected, introduced with the kiln feed through a double-gate airlock or through the side of a long kiln by the use of a charging gate arrangement. All of which are being done successfully in the US and Europe.
Waste Generators
Special Liquid, Semi-Solid and Solid Waste Generators:
Automobile Garages: | Waste Oils Greases Anti-freeze/Coolants Transmission Fluids Tyres |
Refineries: | Tank Bottoms DAF solids API solids Off Spec Product Contaminated Soils Lagoon/Pond cleanups |
Aluminium Industry: | Spent potliners |
Waste Disposal Industry: | Drum Solids Tank Bottoms Contaminated Soils Still Bottoms (distillation bottoms) |
Others: | Various Lube Oils Dried sewage sludges |
Depending upon current or proposed regulations, some of these solids may still be disposed of in landfills. To be able to be utilised in a WDF program, a specially designed solid handling system may need to be designed or constructed for several of these waste streams. This can be accomplished with ERAtech's proprietary solid fuel handling systems.
