哥伦比亚具有通过使用农业部门的剩余生物质生产清洁能源的巨大潜力,例如从大米生产的生命周期中获得的残留物。本文件介绍了一种混合方法方法研究,以检查稻壳的燃烧作为哥伦比亚Tolima部门可能的能源替代品。首先,对稻壳的理化特性进行了分析,对原料进行了表征。接下来,使用SystemAdvisorModel(SAM)软件对生物能源工厂进行建模以获得生物炭,生物油,和来自稻壳燃烧的沼气,并产生性能矩阵,如热效率,热速率,和容量因子。然后,使用净现值(NPV)的数学模型对该项目进行了财务可行性评估,计划期限为5年。最后,调查了当地人口的一部分,以评估对该地区项目的看法。稻壳理化分析结果如下:氮含量(0.74%),有机碳(38.04%),二氧化硅(18.39%),湿度测定(7.68%),灰分(19.4%),碳酸盐的存在(<0.01%),和pH(6.41)。这些性质对于燃烧过程是足够的。SAM模拟表明,锅炉中传递的热量为3180kW,在一年中的12个月内保持50%至52%的效率,意味着稻壳可以发电和热能。财务分析表明,内部收益率(IRR)比机会利率(OIR)高6%,证明项目的经济可行性。稻壳加工厂的设计和创建具有社会和环境可行性,并有可能为Tolima社区的经济发展做出贡献并减少温室气体。同样,这项活动有可能促进消费者的能源安全和环境可持续性,同时具有经济竞争力。
Colombia has great potential to produce clean energy through the use of residual biomass from the agricultural sector, such as residues obtained from the life cycle of rice production. This document presents a mixed approach methodology study to examine the combustion of rice husks as a possible energy alternative in the Tolima department of Colombia. First, the physicochemical characteristics of the rice husk were analyzed to characterize the raw material. Next, System Advisor Model (SAM) software was used to model a bioenergy plant to obtain biochar, bio-oil, and biogas from the combustion of rice husks and generate performance matrices, such as thermal efficiency, heat rate, and capacity factor. Then, the project was evaluated for financial feasibility using a mathematical model of net present value (NPV) with a planning horizon of 5 years. Finally, a subset of the local population was surveyed to assess perspectives on the project in the region. The results of the rice husk physicochemical analysis were the following: nitrogen content (0.74%), organic carbon (38.04%), silica (18.39%), humidity determination (7.68%), ash (19.4%), presence of carbonates (< 0.01%), and pH (6.41). These properties are adequate for the combustion process. The SAM simulation showed that the heat transferred in the boiler was 3180 kW, maintaining an efficiency between 50 and 52% throughout the 12 months of the year, meaning that the rice husk can generate electricity and thermal energy. The financial analysis showed that the internal rate of return (IRR) was 6% higher than the opportunity interest rate (OIR), demonstrating economic feasibility of the project. The design and creation of a rice husk processing plant is socially and environmentally viable and has the potential to contribute to the economic development of the Tolima community and reduce greenhouse gases. Likewise, this activity has the potential to promote energy security for consumers and environmental sustainability while at the same time being economically competitive.
