  4. The integrated system of smelting reduction ironmaking - gasolinesynthesis - electric - ity generation, in which the coal gas produced inthe ironmaking module is first cleaned and then used as the fuel for theelectricity generation module or raw material of the gasoline synthesismodule, can resolve the problem of utilization of tail gas in thesmelting reduction ironmaking and the large investment of gasificationin the integrated gasification combined cycle and gasoline synthesis. taking efficiency, scale and product structure into consideration, the processes of the two - stage smelting reduction ironmaking - combined cycleelectricity generation with coal gas, the two - stage smeltingreduction ironmaking - steam cycle electricity generation with coal gas, the one - stage smelting reduction ironmaking - combined cycleelectricity generation with coal gas, and the one - stagesmelting reduction ironmaking - gasoline synthesis with coal gas - steamcycle electricity generation with tail gas are techno - economicallyfeasible and have the promise of being industrialized

  5. Aimed at solving the problem that high content of unburned carbon is unfavourable for the comprehensive ultilization in scale of fly ash, the fundamental principle that separation of unburned carbon from fly ash is theoretically analyzed by wet flotation and dry electro - separation, three factors and two levels orthogonal test for flotation and two factors and three levels test for electro - separation were conducted, furthermore, the primary factors and law affecting separating efficiency in flotation and electro - separation were obtained. the results show that wet flotation can give 7. 34 % of the cleaned coal yield rate, which contains 44. 53 % of ash content and 56. 02 % of separating efficiency, while dry electro - separation can reduce the content of carbon in separated fly ash to 3. 16 % and remove 53. 12 % of carbon from fly ash

    針未燃炭含量過高不利對粉煤灰大規模綜合利用的問題，從理論上分析了粉煤灰濕法浮選和干法電選分選未燃炭的基本原理，進行了三因素二水平正交浮選試驗和二因素三水平的正交電選試驗研究，得到了影響浮選和電選分選效果的主要因素及其規律.試驗表明:採用濕法浮選法可獲得精煤產率為7 . 34 % ，灰分為44 . 53 % ，分選效率為56 . 02 %的分選效果；採用干法電選，選后粉煤灰的含碳量可降到3 . 16 % ，脫碳率達53 . 12 %
