摘要

摘要:本文研究了混合堆肥废热发电/聚光太阳能电池板(CSP)绿色能源有机朗肯循环(ORC)的可行性。该发电厂的基准是24/7全天候运行,利用堆肥废热,并利用太阳能热能来提高白天的电力输出。本文讨论了电厂的设计,堆肥驱动换热器/锅炉的设计,堆肥堆热分析,CSP分析和模拟电厂输出分析,并对选择异丁烷作为ORC工质进行了论证。为确保该混合动力发电厂的发电成本合理且具有竞争力,进行了平准化能源成本(LCOE)分析。结果表明,混合电厂单独运行堆肥的LCOE为4美分/千瓦时,混合运行堆肥和光热太阳能的LCOE为10.7美分/千瓦时。本文提出的混合堆肥/ORC发电厂的平均能量转换效率为4.3%。将堆肥废热流连接到异丁烷ORC的热交换器的正确设计和选择是堆肥废热电厂运行的核心。本文详细介绍了这种热交换器的设计和分析,以及满足规格要求的商用现货硬件

Compost Waste Heat to Power Organic Rankine Cycle Design and Analysis
Abstract This paper presents a feasibility study of a hybrid compost waste heat to power/Concentrating Solar Panel (CSP) green energy Organic Rankine Cycle (ORC). The power plant is baselined to operate with a duty of 24/7 on compost waste heat and utilize solar thermal energy to boost power output during the day. This paper discusses the design of the power plant, the design of a compost driven heat exchanger/boiler, compost pile thermal analysis, CSP analysis, and simulated power plant output analysis The selection of isobutane as ORC working fluid is justified herein. A Levelized Cost of Energy (LCOE) analysis was performed to ensure that the energy produced by this hybrid power plant would come at a reasonable and competitive cost. The results herein show that the hybrid power plant affords an LCOE of 4 ¢/kWh for compost operation alone and an LCOE of 10.7 ¢/kWh for compost and CSP solar energy operation. The hybrid compost/ORC power plant presented herein affords an average energy conversion efficiency of 4.3%. Centric to the operation of the compost waste heat to power plant presented herein is the correct design and selection of the heat exchanger which interfaces the compost waste heat stream to the isobutane ORC. The design and analysis of this heat exchanger as well as commercially off-the-shelf hardware to meet the specifications is given in detail herein
