【摘要】：為研究太陽(yáng)能引入對(duì)燃煤發(fā)電系統(tǒng)熱力性能的影響,從單耗分析理論出發(fā),建立太陽(yáng)能輔助燃煤發(fā)電系統(tǒng)的單耗模型,對(duì)單純?nèi)济簷C(jī)組和不同集成方式下的太陽(yáng)能輔助燃煤發(fā)電系統(tǒng)的燃料單耗及成本單耗進(jìn)行對(duì)比分析。結(jié)果表明:太陽(yáng)能替代1段抽汽的輔助發(fā)電系統(tǒng)的燃料單耗及成本單耗均最低,分別為284.27 g/k Wh和0.38$/k Wh。在此基礎(chǔ)上,以單耗性能最優(yōu)的集成方案為例,對(duì)太陽(yáng)直射輻射強(qiáng)度(DNI)、集熱面積、油水換熱溫差、煤炭?jī)r(jià)格、集熱器價(jià)格等關(guān)鍵因素對(duì)輔助發(fā)電系統(tǒng)燃料單耗及成本單耗的影響進(jìn)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.
