广东省地热开发利用现状及未来发展探讨
Current status and future development of geothermal energy exploitation in Guangdong province
摘要
Abstract
This paper introduces an overview of geothermal resources and their development and utilization in Guangdong province.Based on the characteristics of geothermal energy in Guangdong province,a combined power generation system incorporating super-long gravity heat pipe and an organic Rankine cycle(ORC)was used to evaluate the power generation potential and economic feasibility of the Fengshun geothermal well in Meizhou and Huangshadong geothermal well in Huizhou.The impact of geothermal effluent temperature on system thermal effi-ciency,self consumption rate,and unit electricity output was analyzed.The results show that both geothermal fields offer significant economic benefits.The capital investment return rate(CIRR)of the Fengshun geothermal well can reach 6.5%(on-grid electricity price is 0.689 Yuan/(kW·h)).For the Huangshadong geothermal well to achieve the same CIRR,the corresponding on-grid electricity price would need to be 0.746 Yuan/(kW·h).Furthermore,some suggestions are proposed from the perspectives of exploration,utilization,technology,management,and industry development,with the aim of promoting the high-quality development of Guangdong's geothermal energy sector.关键词
