steam throttling

The authors have derived a model, which uses statistic average value of differential pressure square root and statistic variance of a throttling set in a two-phase flow system, to estimate the mass flowrate and steam quality.

作者曾从两相分离流模型出发，推导出了利用节流装置在两相流中差压方根的统计平均值和统计方差估计其质量流量及干度的理论模型。

It indicates that there is a possibility to measure two phase flowrate and steam quality by using the simple theoretical model and a single throttling set.

这一论证预示了可以根据简单的理论模型用单一节流装置实现两相流流量和干度的双参数测量。

Steam optimum dispatch is to realize the combination of different value opening under different load in order to minimize the throttling loss.

汽轮机的优化配汽就是根据不同的工况实现不同汽门的组合，以保证节流损失最小。

This article contains three optimization goals: following the load instruction, reducing the throttling losses of turbine high-pressure main steam valve and reducing the amount of fuel.

本文的优化目标有快速跟踪负荷指令、减少汽机高压主汽门节流损失和减少燃料量。
