摘要
「區域能源整合」係溫室氣體減量之重要策略,本研究首先針對國內具潛力之能源供應端與需求端進行調查,並搜研國外成功經驗,期能落實溫室氣體實質減量。由於建立技術及經濟可行之區域能源整合系統,其關鍵因子包括:渦輪機、管線、輸送網絡、及熱儲能系統等,因此管線設置與選擇係進行區域能源整合之重點工作,管線材質選擇須依據使用途徑不同,而承受不同程度之壓力與溫度,將蒸氣或熱水透過管線輸送至需求端;此外,建造區域供熱系統之支出成本,主要係用於安裝配送管網。其中管線材料成本佔55%,因此管線材料與管徑選擇,會最直接影響到整個區域供熱系統建設之總成本。據此,本文針對建置區域能源整合系統之管線成本進行分析;同時,研析建置區域能源系統之蒸汽管材、管徑、管線配置等關鍵因素之評估原則,提出管線成本推估之方法,以將蒸氣能量損失最小化,最佳化整體成本效益。

Implementation of district energy supply (DES) system is considered to be one of the key strategies for mitigating the anthropogenic greenhouse gas (GHG) emissions. This article is to collect the state-of-the-art information regarding DES from countries outside Taiwan and to investigate the feasibility to apply the DES within Taiwan. The details including the qualification of suitable site and determinations of the supply and demand of DES system were proposed. In addition, the cost-benefit analysis of construction of turbine, pipe lines, distribution network and thermal energy storage for the district heating and cooling supply system were evaluated. Various types of pipe lines can be designed and utilized to transfer energy at different transfer conditions of pressure and temperature; for instance, the steam or hot water should be transported to the demand sides by proper designed pipe lines. Because the costs of pipe lines were found to be more than 55% of the total engineering costs, the types of piping material and the diameter of pipe line should optimally selected and determined, respectively. Therefore, the evaluation criteria for constructions of pipe lines and distribution networks were proposed in this article to maximize the overall economic benefit and minimize the energy loss during the steam transportation.
