Abstract
A practical superheated steam drying system is introduced to process high water content waste to solid fuel. Energy consumption and CO2 emissions with this system are evaluated and compared with the result from a conventional waste incinerator. In addition, the temperature and the quantity of superheated steam required for material drying are theoretically estimated. Used paper disposable diapers are processed by the drying system as high water content waste. If the solid fuel is used as an auxiliary fuel to generate superheated steam and results in an efficient waste thermal recycle system, the energy consumption and CO2 emissions become considerably low. As a result, the application of the new superheated steam drying system for processing high water content waste and the obtained solid fuel provide a promising environmentally-friendly waste recycle system.
