A Study on the Scale-Up of Fluidized Bed Combustors for Low-Calorific Value Wastes

저발열량 폐기물 소각용 유동층 소각로의 Scale-Up에 관한 연구

An effective scale-up methodology of fluidized bed incinerators for low calorific value industrial wastes such as paper sludge and sewage sludge has been developed based on the similarity rules. Conventional scale-up theories are briefly reviewed and a new simple theory defining the diffusion Fourier number is established taking account of the lateral mixing of fuels in the fluidized bed. From the design and the operating conditions of the pilot FBC plant at Inchon, important design data for the full-scale incinerators are calculated and discussed.
