peak shaving (為滿足高峰時的需要)從儲罐中抽出液態天然氣。

peak-peak

In this paper , starting from the basic law of fluid me chanics , a mathematical model equation for describing the tran sient flow of the wet gas in the pipeline under peak shaving op eration is established , a simplified treatment for the model equa tion is made and a train of thought for concrete calculation is de signed 文章從流體力學的基本規律出發,建立了描述濕天然氣管道輸送調峰工況下瞬變流的數學模型方程,并對模型方程作了簡化處理,設計了具體的計算思路。

The pressure at every point along the pipeline , the gas - liquid phase flow rate and the law of the liquid holdup in the pipeline chang ing with time in the process of gas storage and supply at the time of peak shaving are simulatively calculated , and based on this , the problem on peak shaving is thoroughly analyzed by combining with the existing pinghu - shanghai gas pipeline in china 模擬計算了調峰過程中管道儲氣和供氣過程沿線各點的壓力、氣液相流速和管內持液率隨時間的變化規律,據此結合我國已建成現有的平湖一上海的天然氣管線,對調峰問題作了深入地分析。

This article analyzes thoroughly problems that unstable combustion , low capacity of peak shaving , low - level automatization etc . occur in peak shaving operation by taking example for boiler mod dg670 / 13 . 7 - 4 本文以dg670 13 . 7 - 4型鍋爐為例,深入的分析了鍋爐調峰運行中存在的燃燒不穩、調峰能力差、自動化程度低等問題。

Steps are revealed that must be taken when boiler without designed capability of peak shaving takes part in peak shaving operation : one is combustion adjustment , the other one modification of burner 明確了沒有設計調峰能力的鍋爐在參與電網調峰運行所應采取的措施:燃燒調整與燃燒器改造。

The diversification of requirement on electronical power market , ask for more and more large power units to join in peak shaving 蓬勃發展的電力市場的需求多樣化,使越來越多的大型機組參與調峰運行。
