查询词典 steam engine

The quantitative and qualitative analysis accordantly show that, steam extraction has little influence on the approach point temperature difference and heat recovery rate; however, the pinch point temperature difference slightly rises with the steam extraction, while the heat end thermal temperature difference greatly drops.

定性分析和解析结果表明，抽汽后接近点温差和余热回收率的变化甚微，节点温差略有增大，但热端端差迅速下降。

B Superheat steam and reheat steam's water spray attemperator

c启动旁路系统、管道及疏水

A new strategy of boiler superheated steam temperature control is presented, which regulates the mass flow of desuperheater spray ahead of time by detecting flue-gas temperature and its change trend to control superheated steam temperature.

提出了一种锅炉过热蒸汽温度控制新策略，即通过检测烟气温度及其变化趋势来提前调节减温水量，从而有效地控制过热蒸汽超温。

On the basis of same main components, comparison and analysis are performed on thermodynamic performance of HAT cycle, STIG (Steam-Injected Gas Turbine) cycle, gas-steam combined cycle and the relevant cycles with intercooling or reheat.

在主要部件相同的基础上，分析比较了HAT循环、注蒸汽燃气轮机循环、燃气—蒸汽联合循环以及各循环采用中冷或再热手段后相应循环的热力性能，确定了再热HAT循环高效率和中冷再热STIG循环高比功的优势，指出中冷手段对循环性能改善不大，回收中冷热量也不会收到好的效果，而再热手段对循环性能改善显著。

Changed the well chamber heating intermedial from the steam to the power plant boiler room's low temperature hot water, and realized the well chamber's steam changes to the water dynamic frequencyconversion constant temperature automatic control.

将井筒供暖热媒由蒸汽改为电厂锅炉房的低温热水，并实现了井筒汽改水动态变频恒温自动控制。

With the fact that steam turbo-generator set capacities ceaselessness enhancing , the steam temperature improving unceasingly, high pressure controlling system adopt to improve development respond to control oil, electric power plant can not adopt the tradition turbine oil to be the navar medium to guard against a conflagration under such situation.

随着汽轮发电机组容量的不断增大，蒸汽温度不断提高，控制系统为了提高动态响应而采用高压控制油，在这样的情况下，电厂为了防止火灾而不能采用传统的透平油作为控制系统的介质。

Comparing with those of steam distillation,the contents of undecane, nonane increased by SPME; and some components that would not be extracted by steam; disti llation were extracted by SPME, such as verbenol,yElenene,calarene,(1)aGurjunene,viridiflorol etc.

结论与水蒸气蒸馏法相比，固相微萃取法得到的十一烷、壬烷等烷烃的含量增加；并且提取出了水蒸气蒸馏法不能蒸馏出来的一些成分，如马鞭草烯醇、γ榄香烯、白菖烯、α古芸烯、绿花白千层醇等。

The steam and nitrogen push uses steam as the heat source ,extra heavy oil or bitumen has been mobilized by conductive heating and rely on the action of gravity of condensed liquid to recovery heavy oil. Because nitrogen is noncondensible gas and its density is lower, nitrogen rise and accumulates in the top of the reservoir.

蒸汽―氮气辅助重力泄油的开采机理是以蒸汽作为热源加热油层，使高粘度的原油、沥青获得较好的流动性，利用气体和液体由于密度不同而产生的垂向分异作用，靠油的重力开采。
