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 Π-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.
