Research on Hydrodynamic Characteristics of Wall System of Efficient Ultra-supercritical П-type Boilers

对于高效参数超超临界燃煤机组,锅炉受热面的安全性对机组长周期安全性提升至关重要,以某600 MWП型锅炉包墙系统为例,建立了典型的包墙系统水动力模型,通过回路划分,分析影响包墙系统受热面安全性的因素,对后续类似项目的设计提供一定的技术支持。

For the efficient ultra-supercritical coal-fired power unit,the safety of the heating surface of boiler is crucial to the long-term safety of the unit.Takes a 660MW П-type boiler wall system as an example to establish a typical hydrodynamic model of the wall system.Through the division of circuits,the influencing factors of safety of the heating surface of the wall system are analyzed,providing certain technical support for the design of subsequent similar projects.
