Abstract
A Waste Reduction Framework Plan was initiated by the Hong Kong Environmental Protection Department in 1998 to set out a 10-year programme and a set of targets for waste reduction. By combining cement production and power generation, waste incineration has improved its competitiveness. The co-combustion of Municipal Solid Waste (MSW) is a novel and highly integrated design combining cement and electricity productions (Co-Co process). By carefully integrating these three processes, energy generated from MSW co-combustion can be used efficiently for cement production and electricity generation. In this process, MSW is incinerated in a rotary kiln with additional fuel followed by the secondary combustion unit (SCU) and extra fuel is burnt in the SCU to raise the combustion temperature to 1200°C. Flue gas exiting from the SCU will then enter a calcinations scrubber for acid gas removal. The flue gas then enters into a waste heat boiler for steam generation. A pilot plant is being designed and will be constructed to test this design.
