| 1. | Such a possibility has been shown theoretically by the double combustion time delay model .
这种可能性已由双燃烧时滞模型从理论上证明了。 |
| 2. | Experimental study on the shortest spontaneous combustion time of 2nd coal in xuecun coal mine
薛村矿2号煤最短自然发火期的研究 |
| 3. | The total flaming combustion time may not exceed 250 seconds for the 10 flame applications for each set of 5 specimens
每一组的5个试片中，若10次火焰燃烧10秒钟移开后，总共火焰燃烧不超过250秒钟。 |
| 4. | The total flaming combustion time may not exceed 50 seconds for the 10 flame applications for each set of 5 specimens
每一组的5个试片中，共10次火焰燃烧10秒钟移开后，总共火焰燃烧的时间不超过50秒钟。 |
| 5. | Heating temperature plays a key role of ignition , otherwise the raw materials cannot be ignited when heating temperature is lower than 400c . there are phenomena that gestation time was shortened , combustion time was lasted , and combustion was accelerated as heating temperature increased
点火温度对反应原料是否能够点燃起决定性的作用，在400以下不能点燃，且随着点火温度的升高孕育期缩短，燃烧时间增长，燃烧越剧烈。 |
| 6. | Biomass fuel is used as reburning fuel to deoxidize no is first experimental studied in this article . conclusions can be drawn from the experimental results that under certain conditions , nox deoxidized efficiency can achieve 50 % - 70 % . compared with coal , biomass volatilization and combustion time is short , so boiler combustion efficiency can be guaranteed
本文首次进行了生物质燃料作为再燃燃料还原no的试验研究，研究表明生物质燃料再燃还原no可以取得非常好的效果，在一定的条件下可以达到50 - 70 ，生物质燃料的挥发分析出和燃烧的时间都要比煤粉短，用作再燃燃料可以有效的保证锅炉的效率。 |
