| 3. | So the study on the dynamical characteristics of the asu is important to the dynamical characteristics and control system of the overall igcc plant
因此igcc空分系统动态特性的研究对于igcc全电站动态特性和控制系统的研究也有很重要的意义。 |
| 4. | But most utilities doubt that igcc plants are suitable for mainstream power generation , because of higher capital costs and frequent breakdowns
但是，大多数公用事业公司怀疑igcc电站是否适用于主流电站，因为它不仅需要更高的资金投入而且故障频繁。 |
| 5. | The attraction of igcc plants , aside from their carbon - capture potential , is that they produce fewer traditional pollutants and also generate hydrogen , which can either be put to industrial uses or burnt
Igcc电站的魅力在于：除了其捕碳的潜力外，它确实能够减少传统的污染物并产生氢气，后者既能用于工业用途也可以进行燃烧。 |
| 6. | In an igcc plant designed to capture co2 , the syngas exiting the gasifier , after being cooled and cleaned of particles , would be reacted with steam to produce a gaseous mixture made up mainly of carbon dioxide and hydrogen
在设有捕集二氧化碳程序的igcc电厂中，合成气离开气化炉、经过冷却并去除粒子之后，会与蒸汽作用，产生主成份为二氧化碳和氢的混合气体。 |
| 7. | Besides , the dynamical characteristics of the asu also have great influence on those of the overall igcc plant . it ' s long start - up time and off - design regulation time have great restriction on flexibility and reliability of the overall plant
另外，空分系统的动态特性对igcc电站的动态特性也有很大的影响，其启动时间长，工况调整时间也很长，在很大程度上影响了整个电站的运行灵活性和可靠性。 |

其次，本文以荷兰buggenum电站的空分系统为原型，基于matlab建立了空分系统精馏塔的半图形化动、静态数学模型，并通过模拟，得出了一些有价值的结论：当空分系统的压力变化时，氧气产品浓度的响应时间常数为两小时左右，说明空分系统是igcc电站最大延迟环节；而且虽然氧气浓度最后会稳定在igcc电站所要求的范围之内，但在过渡过程中会超出限制，这些都为igcc电站的安全运行及控制系统设计提供了有价值的信息。 |
| 9. | Asu , especially the configuration between the asu and gas turbine has great impact , which concentrates on the power consumption by the asu , on the igcc power output , overall efficiency and the net cost of power generation of the igcc plant . therefore , it is significant to make a study on the relationship between the asu and gas turbine and the factors which influence the power consumption by the asu
空分系统的选择，特别是空分系统与燃气轮机的配置关系，对igcc电站的供电效率、功率输出及净发电成本都有很大的影响；而这些影响，集中表现在空分系统的能耗之上，因此研究空分系统配置与能耗的关系以及空分系统的能耗规律及其影响因素至关重要。 |
