新型储换热系统在热电联产电厂灵活性改造中的应用

Application of New-type Heat Storage and Exchange System in Flexibility Retrofit of Combined Heat and Power Plant

为提升热电联产机组调峰能力,同时提供稳定参数蒸汽,满足对外供热需求,提出一种全新的混凝土储热换热系统,介绍了典型应用案例的系统参数设计方法,通过系统模块的实际工程应用,证明该系统可以实现机组的"热电解耦",提高机组的运行灵活性,为电厂带来"增加调峰补贴"与"工业供汽"的双重收益。

To promote the peak-shaving ability of combined heat and power plants, meanwhile provide stable steam to satisfy the steam supply demand, brand new concrete heat storage and exchange system has been designed.The system parameter design method of a typical application case is introduced.The system modules all have practical engineering applications.Thus proved the application of this system can realize the thermoelectric decoupling and enhance the operation flexibility of the unit. Thus can increase the income of peak-shaving subsidies and industrial steam sell for the power station.
