  1. Ruburning with coal has been proved a effective low nox emission combustion technology 。 in this ph. d thesis, the reaction mechanisms of reburning have been investigated, and the homogeneous and heterogeneous reduction of nox have been analyzed in details. a series of reburning experiments have been carried out on an entrained - flow reactor, in which two kinds of coals with different particle sizes have been used

    本文對煤粉再燃過程中,揮發分及煤焦的基元反應途徑和反應機理進行了詳細分析;在攜帶爐實驗臺上進行了神華煤、邢臺煤在1200與1300 、四種煤粉細度、三種再燃燃料比和三種再燃區初始氧量,共144個實驗工況下的再燃實驗。
  2. This flexion of graph can be defined as criterion of coal ignition character under excessive oxygen supply. based on viewpoints of coal ignition, we put forward assumption aiming at ignition character of coal with excessive oxygen. in this thesis, with comparison of average temperature increase among eleven kinds of coal, the following are obtained : homogeneous ignition happens when coal has higher volatile matter and there is a approximative direct - ratio relationship between temperature hoist before flexion and content of volatile matter ; on the other side, heterogeneous ignition occurs for the coal with lower volatile matter content because of collective influence of volatile matter and fixed carbon combustion, and one - to - one relationship between temperature increase before flexion and content of volatile matter does not exit

    以煤著火性質研究的觀點為基礎,對煤在過氧條件下的著火性質提出假設,通過11種標準煤樣在過氧條件下燃燒實驗,對比了拐點前後平均溫升與煤樣成分的關系,證實了揮發分含量較高的煤在過氧條件下發生均相著火燃燒,拐點前後量熱系統的溫升分別與揮發分和固定炭的含量成近似正比的關系;而揮發分含量較低的煤在過氧條件下發生非均相著火燃燒,拐點之前量熱系統的溫升由於受到揮發分和固定炭同時燃燒的影響,因而不存在溫升與揮發分含量之間單一的對應關系。
  3. On the basis of comprehensive analyses on hydrocarbon accumulation conditions in the four representative foreland basins, kuqa basin, southern junggar basin, western sichuan basin and northern margin of qaidam basin, some conclusions are made as follows ; the foreland basins in central and western regions of china are characterized by multi - set source rocks dominated by coal measure ; heterogeneous reservoirs ; multiple and sealing cap nick ; anticline traps ; unblocked transport system composed of fault, unconformity and highly permeable sand body ; anti poor conservative conditions. etc

    在綜合分析和對比庫車、準南、柴北緣和川西等具有代表性的前陸盆地的油氣成藏條件的基礎上指出,中西部前陸盆地具有以煤系為主的多套源巖,發育非均質儲集層,多套多封閉性的蓋層,以背料為主要圈閉;斷裂、不整合和高滲透砂體組成良好輸導體系,保存條件較差等特點。
