充分利用现有资产是工业界的一个高度优先事项，特别是在需要大量资本支出来建设替代能力以满足如果这些资产停止使用的持续需求的情况下。在这种情况下，改造现有发电厂的二氧化碳（CO2）捕获，使他们能够继续在合理的未来情况下，电力部门需要显着削减CO2排放量的潜力已成为一个越来越“热门话题”。在CO2捕获改造评估中通常被忽视的改造工厂的一个潜在重要特征是，它们可能具有“内在灵活性”。例如，对于改造燃烧后捕集而不对动力循环进行任何重大改变的电厂（即在增加捕集时不进行锅炉/涡轮机改造），电厂通过暂时绕过捕集装置来避免与运行CO2捕集相关的大部分效率损失在技术上应该是可行的。低压蒸汽涡轮机、冷凝器和发电机的尺寸应确保其能够使用从CO2捕集装置分流的蒸汽进行发电，而无需任何额外支出，因为在安装捕集装置之前，该蒸汽已包含在设计流量中。本文和相关的博士论文有助于发展的燃煤电厂改造与燃烧后捕获和富溶剂的临时存储相关的潜在增强内置的灵活性的潜在价值的理解。这种分析对于为投资和政策决策提供信息非常重要，并将工程和经济评估结合在一起。因此，它能够得出强有力的结论，在确定未来的技术设计工作的优先事项和决定哪些模式的操作灵活性可能是足够有价值的，以保证在投资评估或政策制定有关改造燃烧后捕集煤粉厂进一步分析。
Making best use of existing assets is a high priority for industry, particularly when significant capital expenditure would be required to construct replacement capacity to meet continued demand if they were taken out of service. In this context, the potential to retrofit carbon dioxide (CO2) capture to existing power plants so that they can continue to operate in plausible future scenarios where significant cuts in CO2emissions are required from the electricity sector has become an increasingly ‘hot topic’. One potentially important characteristic of retrofitted plants that is typically over-looked in assessments of CO2capture retrofit is that they are likely to have ‘built-in flexibility’. For example, for plants that retrofit post-combustion capture without any significant changes to the power cycle (i.e. that do not undertake a boiler/turbine retrofit at the time as adding capture), it should be technically feasible for the plant to avoid the majority of the efficiency penalty associated with operating CO2capture by temporarily bypassing the capture unit. The low pressure steam turbine, condenser and generator will be sized so that they are able to use the steam that is diverted away from the CO2capture unit for power generation without any additional expenditure, since this steam was included in the design flow before capture was fitted. This paper and a related PhD thesis contributes to developing understanding of the potential value of built-in flexibility of coal-fired power plants retrofitted with post-combustion capture and potential enhancements associated with temporary storage of rich solvent. This analysis is important to inform investment and policy decisions and brings together engineering and economic assessment. Thus, it is able to draw robust conclusions that are relevant in determining both priorities for future technical design work and decisions about which modes of operating flexibility may be sufficiently valuable to warrant further analysis within investment appraisal or policy-making related to retrofitting post-combustion capture to pulverised coal plants.
