摘要

A novel design of an integrated process for cement production incorporating municipal solid waste (MSW) separation and combustion has been developed.The novel design offers significant opportunities for waste minimization.The MSW combustion system design incorporates the use of supplementary fuel from waste marine oil.Very high temperature,1200°C,high turbulence and high residence time,>4 s,are achieved.This results in very high burnout of MSW,resulting in negligible particulate organic matter to form dioxin by de-novo synthesis.The energy produced is used for the cement process calcination of limestone and residual heat is converted into energy to drive the cement plant.The calcination process itself is used as a large scrubber to remove SO_X and HC1,the latter minimizing the chance of dioxin formation further.A front end materials recovery and recycling facility,MRRF,is used to remove valuable recyclable components,chlorine-based plastics and metal-containing materials,such as batteries.The combustion of the MSW achieves a 85-90% volume reduction and the MSW ash is used as a feedstock for the production of the cement clinker.
