能量梯级利用理论下煤基液体燃料-动力多联产系统的集成与优化

Integration and Optimization of Coal Based Liquid fuel Power Multi Production System under the Theory of Energy Cascade Utilization

在我国能源结构中,化石燃料占据主体地位,具有"富煤、少气、贫油"的特点,此种背景下,转化及传递煤炭资源时,需综合优化物质及能量的利用情况。集成煤基化工-动力多联产系统后,实现高效、低碳利用煤炭资源,且有利于将能源短缺等一系列问题有效解决,促进社会、环境及经济的和谐发展。能量梯级利用理论是集成煤基化工-动力多联产系统的基础,其可将物质转化及能量传递中多联产系统节能潜力的关键之处及基本规律真实的反映出来。基于此,在能量梯级利用理论基础上,分析了集成与优化煤基液体燃料-动力多联产系统的思路及方法。

In our country＇ s energy structure, fossil fuels occupy the dominant position, has the characteristic of＂rich coal, gas and oil＂, under this background, transformation and transfer of coal resources, the utilization of material and energy for comprehensive optimization.After integrating the coal based chemical and power poly generation system, we can achieve efficient and low carbon utilization of coal resources, and help solve a series of problems such as energy shortage and promote the harmonious development of society, environment and economy.The theory of cascade utilization of energy is the foundation of the integrated coal based chemical power and power generation system.It can reflect the key points and basic laws of energy saving potential in the material conversion and energy transmission system.Based on this, this paper analyzes the idea and method of integrating and optimizing the coal based liquid fuel-power multi-production system on the basis of the theory of the energy cascade utilization.
