摘要
在这里进行的研究旨在确定使用就地发电设施与传统发电机的优势,并从环境的角度进行评估。为此,对二氧化碳产生的环境分析已应用于麦德林市(哥伦比亚)一座住宅楼的两种发电方案。第一个是位于Antioquiashire Puerto Nare市La Sierra的La Sierra热电厂,这是哥伦比亚火力发电效率最高的电厂。第二个比较方案是指微型热电联产设备的年度运行,该设备满足建筑物的热水和电能需求。利用TRNSYS v17®能源模拟软件的功能和公共领域可用的排放方程,在相同的负载下,在一个和另一个之间进行比较环境分析。假设电力传输中的损耗为10%。该分析显示,两者的排放量差异超过50%,主要原因是使用的燃料数量,两种情况下都是天然气。另一方面,本研究显示了使用原位发电机的环境优势,减少了传输损耗。
Techno-environmental assessment of a micro-cogeneration system based on natural gas for residential application
The study carried out here aims to determine the advantage of using in-situ electricity generation facilities versus conventional generators, being evaluated from the environmental point of view. For this, an environmental analysis on the production of CO2 has been applied to two scenarios of electricity generation for a residential building in Medellin city (Colombia). The first one refers to La Sierra thermo-electric plant located in La Sierra, municipality of Puerto Nare, in the Antioquiashire, which is the most efficient plant in Colombian thermal generation. The second comparison scenario refers to the annual operation of a micro-cogeneration facility, which satisfies the building’s hot water and electrical energy needs. Using the capabilities of the TRNSYS v17® energy simulation software and the emission equations available in the public domain, the comparative environmental analysis is carried out between one and the other for the same load. The losses in electric transmission are assumed to be 10%. This analysis has shown a difference of more than 50% in emissions generation, with the main cause being the amount of fuel used, which for both cases is natural gas. On the other hand, this study shows the environmental advantages in the use of in-situ generators, decreasing transmission losses.
