reheat steam meaning in English
再热蒸汽
Examples
- Specifications for bending pipe of steam turbine main and reheat steam piping
汽轮机主器管和再热器管的弯管技术条件 - Analysis of low temperature of reheat steam of a 670t h boiler and corresponding measures
锅炉再热蒸汽温度偏低的原因分析 - In the whole system , the inner leak system is occurred to the lower pressure bypass system , this will directly cause the high quality reheated steam to reach to condenser , meanwhile increase the heat load of condenser , and the economy benefit of the unit will decreased
整个系统存在的内漏主要是低压旁路低压旁路的泄漏,直接造成了高品质的再热蒸汽短路到凝汽器,同时增加了凝汽器的热负荷,对机组经济性的影响较大。 - There are many plants that have the character of time - varying , large delay , large inertia in the process of production of modern power station such as the superheated steam temperature , the reheated steam temperature , the water treatment of boiler and the load regulation . some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control . it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control , optimal control ， decoupling control and predictive control . and these control systems have large calculation and bad character of real time in general . these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station . now the generator units are developing towards large capacity and high parameters . many new kinds of generating electricity means are coming into being . the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict . the new control means are in bad need to control them effectively
现代电站的生产过程中存在过热汽温、再热汽温、锅炉水处理、负荷调节等许多大迟延、大滞后、特性时变的对象，它们中有些还是具有强非线性特性的对象或多变量耦合系统，采用常规的pid控制手段很难取得良好的控制效果。若应用现代控制理论中的自适应控制、最优控制、解耦控制、预测控制等控制手段，则需要建立被控对象的数学模型，而且往往控制系统的计算量大、实时性差。这些缺点使其很难满足实际生产过程的需要从而极大地限制了其在现代电站中的应用。
