| 摘 要： | 在役火力发电厂汽轮机排汽通过冷却装置凝结后进入凝结水系统,期间存在大量冷源损失,因此火电厂冷源损失的利用越来越引起关注。针对应用于降低冷源损失的低真空改造和吸收式热泵改造两种方案,运用定性分析的设计思想进行计算,从改造的边界条件及经济效益等方面进行分析与探讨,为火电厂的余热利用改造提供参考。

| Abstract: | In the existing thermo-power plants, the exhaust of steam turbines runs through the cooling system before pumped into the condensate system, which leads to large amount of cold source loss. In consider of that, the cold source loss utiliation of thermo-puw- er plants has drawn more and more attention. This paper discusses two typical modes to reduce the cold source loss, one is the low vacuum renovation anti the other is absorption heat pump renovation. Qualitative analysis and design calculation results are used to study and discuss the boundary conditions and economic benefit of the renovation, providing reference for the the waste heat utilization of thermo-power plants. |
