| 中文摘要 | the calcination process may influence subsequent fragmentation, sintering and swelling when cao derived from limestone acts as a co(2) or so(2)-sorbent in combustion, gasification and reforming. sorbent properties are affected by co(2) partial pressure, total pressure, temperature, heating rate, impurities and sample size. in this study, the effect of calcination heating rate was investigated based on an electrically heated platinum foil. the effects of heating rate (up to 800 degrees c/s), calcination temperature (700-950 degrees c), particle size (90-180 mu m) and sweep gas velocity were investigated. higher initial heating rates led to lower extents of limestone calcination, but the extents of carbonation of the resulting cao were similar to each other. calcium utilization declined markedly during carbonation or sulphation of cao after calcination by rapid heating. experimental results show that carbonation and calcium utilization were most effective for carbonation temperatures between 503 and 607 degrees c. increasing the extent of calcination is not the best way to improve overall calcium utilization due to the vast increase in energy consumption. |
