1DEVELOPMENT POTENTIALS AND RESEARCH NEEDS IN CIRCULATING FLUIDIZED BED COMBUSTION显示文摘First a report about present status of circulating fluidized bed reactors for coal and multi-fuel combustion in power plants is given. Thereafter the development potentials and research needs for further improvement of CFB com-bustors operating with finely grained bed materials are discussed and recommendations for direction of further research and development work are presented.Lothar Reh 2003China Particuology2003,1,5:11
2循环流化床能量最小多尺度作用模型显示文摘本文建立了完整的循环流化床流体动力学数学模型。内容包括顶部稀区和底部密区局部状态的模拟和径向分布的计算。并确定了两区共存和三种不同操作方式存在的条件。研究表明,能量最小在循环流化床的气固相互作用中起着重要的作用。顶部稀区和底部密区的气固相互作用机理完全不同。底部密区处于颗粒流体协调(FPC)状态,其稳定条件是悬浮输送能耗N_st等于最小值;而顶部稀区处于流体控制状态,其稳定条件是N_st=最大值或W_st=最小值。(W_st)_FPC=(W_st)_FD时,两区共存或过渡,系统处于饱和夹带状态。两个区域中的径向分布也都必须满足相应的整体稳定性条件。李静海 郭慕孙 Lothar Reh 1992中国科学(B辑)1992,B,11:5
3Process engineering in circular economy显示文摘Driven by increasing global population and by growing demand for individual wealth,the consumption of energy and raw materials as well as the steadily growing CO_2 concentration in atmosphere pose great challenges to process engineering.This complex multi-scale discipline deals with the transformation of mass by energy to manifold products in different industrial fields under economical and ecological sustainable conditions.In growing circular economy,process engineering increasingly plays an important role in recovering valuable components from very diffuse material flows leaving the user stocks following widely variable time periods of use.As well it is engaged in thermal recovery of energy therefrom and in environmentally safe disposal of residual solid wastes whose recovery economically is not feasible.An efficient recovery of materials and energy following the laws of entropy is a must.A complex network of mass,energy,transportation and information flows has to be regarded with growing traded quantities of used goods even on global level.Important constraints in time,however,exist for a necessary realization of innovative new processes and communal mobility and industrial infrastructure on medium and large scale.Based on reasonable long term and highly reliable statistics from industrial organizations representing steel and paper industry,some limits and trends of possible developments in processing of those industries with long recycling experience will be discussed.Lothar Reh 2013Particuology2013,11,2:3

8Focus on solids strand formation improves separation performance of highly loaded circu- lating fluidized bed recycle cyclones 显示文摘Erich Hugi Lothar Reh 2000Chemical Engi- neering and Processing2000,39,3:1
9CHALLENGES FOR PROCESS INDUSTRIES IN RECYCLING显示文摘Increasing population and individual wealth have led to a higher demand for energy and raw material re- sources as well as for steady improvement of processing technology in view of efficient use of resources and avoiding emissions in production and recycling processes. Present situation and future trend of recycling processing are dis- cussed by examples from the aluminium and steel industries, recycling of cars and post-consumer municipal recovery. The importance of more intense observance of thermodynamic laws and of a 4E strategy “Economy, Energy, Environ- ment and Education” is outlined.Lothar Reh 2006China Particuology2006,4,2:1
10气固垂直并流上行流态化不均匀性的机理显示文摘一、引言 不均匀性是各类两相流,尤其是气固流态化最显著的特征之一。因而成为流态化研究的焦点。然而目前的研究还只限于对不均匀结构的实验考察和改善这种结构的尝试。对于不均匀结构产生的机理并不十分清楚,改善这种结构的研究也缺乏依据。 本文将在多尺度作用能量最小(EMMS)模型的基础上,进一步分析不均匀结构产生的机理,定量阐明将它归因于能量最小的机制。李静海 郭慕孙 Lothar Reh 1991工程热物理学报1991,12,4:1
