【摘要】：太陽能輔助燃煤發(fā)電系統(tǒng),能夠?qū)崿F(xiàn)太陽能熱能與傳統(tǒng)火力發(fā)電生產(chǎn)相互耦合,減少傳統(tǒng)火力發(fā)電過程的燃煤消耗,有利于促進(jìn)電力生產(chǎn)過程的節(jié)能減排。論文主要研究槽式太陽能輔助燃煤發(fā)電系統(tǒng)的能量分布特性和優(yōu)化潛力,主要研究內(nèi)容和成果如下： 首先針對槽式太陽能集熱場的工作運(yùn)行特點(diǎn)以及某330MW火力發(fā)電機(jī)組各個(gè)設(shè)備的運(yùn)行特點(diǎn),建立了太陽能輔助燃煤發(fā)電系統(tǒng)的基本模型,通過對模型進(jìn)行驗(yàn)證,確定該模型的準(zhǔn)確性,作為進(jìn)一步分析計(jì)算的基礎(chǔ)。 其次,論文以熱力學(xué)第二定律為基礎(chǔ),分析了太陽能輔助燃煤發(fā)電系統(tǒng)在不同運(yùn)行負(fù)荷下的(?)能特性,得到了該系統(tǒng)能量分布和利用狀況,并與傳統(tǒng)火力發(fā)電機(jī)組的(?)分布特性進(jìn)行了分析比較,確定了引入太陽能耦合后發(fā)電系統(tǒng)的(?)能利用優(yōu)點(diǎn)。 再次,論文在傳統(tǒng)的(?)分析法基礎(chǔ)上,對太陽能輔助燃煤發(fā)電系統(tǒng)采用了不可避免(?)損失分析,在已知該發(fā)電系統(tǒng)各個(gè)設(shè)備的(?)能利用狀況的前提下,結(jié)合相關(guān)設(shè)備的特點(diǎn),分析了各個(gè)設(shè)備(?)損中能夠再次開發(fā)利用的部分,為系統(tǒng)的優(yōu)化利用改造提供一定的參考。 最后,論文對太陽能輔助燃煤發(fā)電系統(tǒng)進(jìn)行可(?)經(jīng)濟(jì)性能分析,并以此為前提,結(jié)合不可避免(?)損失分析法,對該系統(tǒng)進(jìn)行了不可避免(?)損失的經(jīng)濟(jì)性能分析,確定了太陽能輔助燃煤發(fā)電系統(tǒng)中各個(gè)設(shè)備優(yōu)化改造的優(yōu)先級,作為設(shè)備運(yùn)行和投資優(yōu)化的基礎(chǔ)。
[Abstract]:Solar assisted coal-fired power generation system can realize the coupling of solar thermal energy and traditional thermal power production, reduce the coal consumption of traditional thermal power generation process, and promote the energy saving and emission reduction of power production process. This paper mainly studies the energy distribution characteristics and optimization potential of channel solar assisted coal-fired power generation system. The main research contents and results are as follows: Firstly, the basic model of the solar assisted coal-fired power generation system is established according to the working characteristics of the trough solar energy gathering field and the operation characteristics of each equipment of a certain 330MW thermal generating unit, and the model is verified. The accuracy of the model is determined as the basis for further analysis and calculation. Secondly, based on the second law of thermodynamics, the paper analyzes the solar assisted coal-fired power generation system under different operating loads. The energy distribution and utilization of the system are obtained and compared with that of the traditional thermal generator set. The distribution characteristics are analyzed and compared, and the power generation system with solar energy coupling is determined. Be able to take advantage of advantages. Thirdly, the thesis is in the traditional form. On the basis of the analysis method, the solar auxiliary coal-fired power generation system is inevitably adopted. Loss analysis, where the equipment of the power generation system is known According to the characteristics of the related equipments, this paper analyzes each equipment on the premise of its utilization. The damaged parts can be redeveloped and utilized, which provides a certain reference for the optimization and transformation of the system. Finally, the solar assisted coal-fired power generation system can be used in this paper. Economic performance analysis, and on this premise, combined with the inevitable) The loss analysis method is applied to the system. Based on the analysis of the economic performance of the loss, the priority of each equipment in the solar assisted coal-fired power generation system is determined, which is the basis of the equipment operation and investment optimization.
