【摘要】：为研究太阳能引入对燃煤发电系统热力性能的影响,从单耗分析理论出发,建立太阳能辅助燃煤发电系统的单耗模型,对单纯燃煤机组和不同集成方式下的太阳能辅助燃煤发电系统的燃料单耗及成本单耗进行对比分析。结果表明:太阳能替代1段抽汽的辅助发电系统的燃料单耗及成本单耗均最低,分别为284.27 g/k Wh和0.38$/k Wh。在此基础上,以单耗性能最优的集成方案为例,对太阳直射辐射强度(DNI)、集热面积、油水换热温差、煤炭价格、集热器价格等关键因素对辅助发电系统燃料单耗及成本单耗的影响进行分析。
[Abstract]:In order to study the influence of solar energy introduction on the thermal performance of coal-fired power generation system, the unit consumption model of solar assisted coal-fired power generation system is established based on the theory of unit consumption analysis.The fuel unit consumption and cost unit consumption of solar-assisted coal-fired power generation system with different integrated modes are compared and analyzed.The results show that the unit fuel consumption and cost per unit consumption of the auxiliary generation system with solar energy instead of one stage extraction are the lowest, which are 284.27 g / k Wh and 0.38% / k what, respectively.On this basis, taking the integrated scheme with the best unit consumption performance as an example, the direct solar radiation intensity, heat collecting area, oil and water heat exchange temperature difference, coal price,The effects of collector price and other key factors on fuel consumption and cost per unit consumption of auxiliary power generation system are analyzed.
