摘　　要：考虑到化石燃料的环境污染和成本波动等问题,发展可再生能源技术是未来可持续能源供应的必要和必然。与太阳能和风能相比,地热能在一天中的所有时间都是可利用的。这种可再生能源适用于供暖、制冷、淡水和电力的清洁供应。地热能除了作为主要能源直接用于发电外,还可以作为辅助热源用于预热,减少温室气体排放,节约燃料。在这些系统中,利用地热热源的热量进行蒸汽预热。此外,地热能可用于其他能源系统,如制氢装置,用于预热电解过程中消耗的水。针对利用地热能进行预热的优势,综述了地热能预热系统的应用研究。通过这一研究可以看出,利用地热能进行预热在节约燃料和提高性能方面具有很大的潜力。上述系统的性能取决于系统的配置、钻孔规格和地热源温度等因素。通过实施优化,可以进一步改进这些系统。Considering the issues related to the usage of fossil fuels namely the environmental pollutants and fluctuations in their cost,development of renewable energy technologies is necessary and inevitable for sustainable energy supply in future.Geothermal energy is advantageous compared with solar and wind in term of availability in all hours of a day.This renewable energy source is applicable for supplying heating,cooling,freshwater and power in a clean way.Aside from direct utilization of geothermal energy for power generation as the main energy source,it is possible to apply it as auxiliary source for preheating in order to reduce greenhouse emissions and fuel saving.In these systems,thermal content of geothermal energy source is used for steam preheating.Furthermore,geothermal energy could be used in other energy systems like hydrogen production unit for preheating electrolysis water consumed in this process.Regarding the advantages of utilization of geothermal energy for preheating purposes,this paper aims to review studies on the applications of geothermal preheating systems.According to the studies on this subject,it can be denoted that there is significant potential for fuel saving and performance improvement by means of geothermal energy for preheating purpose.The performance of the aforementioned systems depends on some factors namely the configuration of the system,specification of the boreholes and temperature of geothermal source.Further improvement of these system is achievable by implementation of optimization.
