Energy Efficiency Improvement Opportunities for the Cement Industry

摘要: This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number technologies measures applicable to cement industry. The include both state-of-the-art that are currently in use enterprises worldwide as well advanced either only limited or near commercialization. focuses mainly retrofit using commercially available technologies, but many these for new plants well. Where possible, each technology measure, costs savings per tonne produced estimated then calculated based fuels used at process step which measure is applied. analysis kiln energy-efficiency opportunities divided into different stages production various types China: raw materials (and fuel) preparation; clinker making (applicable all kilns, rotary kilns only, vertical shaft only); finish grinding; plant wide product feedstock changes will reduce consumption making. Table 1 lists this by they apply, including changes. Tables 2 through 8 provide following technology: fuel electricity cement; annual operating capital payback period; and, applied cement. was originally collected U.S. industry (Worrell Galitsky, 2004) China's (Price press). provided publicly-available reports, journal articles, case studies from applications around world.
