| 摘 要： | 采用Visual C++编程计算了所设计的蒸汽发生系统热力参数,分析其变工况性能,获得调控规律。基于该蒸汽发生系统,计算了化学回热循环燃气轮机的设计点和变工况性能。随着供入蒸汽发生系统的能量增加,蒸汽产量逐渐升高并维持在一个最大值,该最大值由高压闪蒸的压力决定。以蒸汽产量为蒸汽系统的设计目标时,补给水流量的最优值是设计点的值。化学回热循环系统较原型机效率提高,NO_x排放减少,环境热污染减小。 |
| 关 键 词： | 燃气轮机 余热回收 蒸汽发生系统 变工况 |

| Abstract: | In this paper, the program in Visual C++ is used to calculate the performance of the designed heat recovery steam generator (HRSG) to analyze its performance under variable conditions and derive the control strategies. Based on the HRSG, the performance of the designed and variable conditions of a chemically recuperated gas turbine(CRGT) are calculated. The results show that as the energy fed into the HRSG grows, the steam production grows and maintains a maximum value which is determined by the flasher pressure. When the steam production is set as the designed object, the optimal feed water volume is the designed value. The efficiency of CRGT is better than that of the prototype with less NOx emission and reduced thermal pollution. |
