Abstract

Steam power plants have a considerable potential to meet the growing energy demand, but its dependence on conventional fossil fuels has hampered its viability. One of the ways to minimize fuel consumption and upgrade the performance of a Rankine cycle is by incorporating closed feedwater heaters(FWHs). The datasets contained in this paper are thermodynamic performance analysis carried out on reheat - regenerative steam power plant with FWHs using CyclePad V2.0 software. The thermodynamic performance indices assessed are thermal efficiency, network output, heat rate, fuel consumption, boiler efficiency and specific steam consumption. Result obtained show that an increase in the number of FWHs decreases the fuel consumption, heat rate, heat rejected in condenser and heat input to the cycle. This effect invariably can lead to a reduction in operating cost and environmental impacts.

摘要

蒸汽发电厂在满足不断增长的能源需求方面具有相当大的潜力，但其对传统化石燃料的依赖阻碍了其可行性。减少燃料消耗并提升朗肯循环性能的方法之一是采用闭式给水加热器（FWH）。本文包含的数据集是使用CyclePad V2.0软件对带有FWH的再热回热蒸汽发电厂进行的热力性能分析。评估的热力性能指标包括热效率、净输出、热耗率、燃料消耗、锅炉效率和单位蒸汽消耗量。所得结果表明，FWH数量的增加会降低燃料消耗、热耗率、凝汽器中的排热以及循环的热输入。这种效果必然会导致运营成本和环境影响的降低。
