机组母管制给水系统分配方案的研究

Research on feed-water distribution scheme in fossil-fired power station

基于等效焓降理论,得出了包含机组完善程度的系数——纯热量品位系数:通过该系数建立火电厂机组母管制给水系统分配数学模型,并提出了机组给水系统分配判据参数,利用该参数合理地优化各机组间的给水分配方案。实际应用表明,优化后的机组给水分配方案提高了电厂经济效益。

Based on the Equivalent Heat Drop Theory, the pure heat quality grade coefficient is deduced. The mathematical model of distribution scheme of feed-water in the fossil-fired power plant with a number of boilers feeding into a range is presented and a criterion parameter is put forward. The feed-water distribution of every boiler unit is optimized reasonably and economical gains are obtained through practical application.
