Abstract

This study focuses on designing a solar thermal system utilizing parabolic trough collectors to replace conventional heat requirements in industrial processes. The research also assesses the impact of implementing this system on reducing CO2 emissions and provides economic analysis for industrial cities from two geographically different islands in Indonesia: Java and Sulawesi. This study uses a parabolic trough collector to absorb energy from sunlight. Based on the calculation of the energy balance of the solar collector, the average heat absorbed by the collector is 545.5 kJ m−2 h−1 in Java and 606.5 kJ m−2 h−1 in Sulawesi. As a result, approximately 67.55 tonnes of CO2 per day will be mitigated by transitioning from conventional processes. The economic analysis indicates a payback period of 3.54 years, a net present value of 1.4 million USD, and an internal rate of return of 12 % based on fuel savings.

印尼太阳能热利用在工业中的应用分析

本研究的重点是利用抛物面槽式集热器设计太阳能热系统，以替代工业流程中的传统热需求。研究还评估了实施该系统对减少二氧化碳排放的影响，并为印度尼西亚两个地理位置不同的岛屿上的工业城市提供了经济分析：爪哇岛和苏拉威西岛。这项研究使用抛物面槽式集热器从太阳光中吸收能量。根据太阳能集热器的能量平衡计算，集热器吸收的平均热量在爪哇岛为 545.5 kJ m-2 h-1，在苏拉威西岛为 606.5 kJ m-2 h-1。因此，通过从传统工艺过渡，每天可减少约 67.55 吨二氧化碳。经济分析表明，投资回收期为 3.54 年，净现值为 140 万美元，根据节省的燃料计算，内部收益率为 12%。
