摘要
针对某350MW超临界机组通流改造热力设计问题,从系统配置、通流选型等方面进行了分析和论述,给出目前最合理的改造方案。结果表明,通流改造后的机组热耗较改造之前可降低386.2kJ/(kW·h),收益明显。
In view of the thermal design problem of a 350MW supercritical unit,this paper analyzes and discusses the system configuration and flow selection,and puts forward the optimal transformation scheme.The results show that the heat consumption of the unit can be reduced by 386.2kJ/(kW·h)after the transformation,and the benefit is obvious.
