毕业设计（论文）题目地热能-干热岩发电、集中供暖专业热能与动力工程班级2015年摘要能源是人类社会赖以生存与发展的基础，人类的任何生产与生存活动都离不开能源。长期以来，石化燃料对世界经济的高速发展有着深远的影响，给人类带来前所未有的繁荣与幸福。但是，直到最近我们才开始完全认识到人类过度开采和滥用石化资源所带来的灾难和为此所付出的沉重代价，人类所面临的挑战已经很清晰。近年来，虽然政府对集中供热系统建设的投入逐年上升，但我国集中供热覆盖率仍处于较低水平，目前仅在北方各省的主要城镇建有集中供热系统，且平均覆盖率不到50%。北方主要城镇的供暖基本为市政集中供暖、天然气供暖等供热方式。集中供暖方式的热量及供暖范围已远远达不到现阶段居民取暖的需求。随着节能减排淘汰落后产能政策在全国的推广，地热及干热岩等具有节约燃料和减少环境污染特点的新型能源，在未来将成为我国主要的集中供热方式。关键词：地热能源；可再生能源；地热发电；集中供暖；干热岩AbstractEnergyisthebasisforthesurvivalanddevelopmentofhumansociety,andhuman'sproductionandlivingactivitiescannotbeseparatedfromtheenergy.Foralongtime,fossilfuelshaveaprofoundimpactontherapiddevelopmentoftheworldeconomy,whichhasbroughtunprecedentedprosperityandhappinesstomankind.But,untilrecently,wehaveonlybeguntorealizethatthehumanoverexploitationandabuseoffossilresourcesandtheheavycostofhumanresources,thechallengesfacinghumanityhasbeenveryclear.Inrecentyears,althoughthegovernmenthasincreasedtheinvestmentintheconstructionofcentralheatingsystem,butChina'scentralheatingcoverageisstillatalowlevel,onlyinthenorthofthemaincitiesandtownsarebuiltacentralheatingsystem,andtheaveragecoverageislessthan50%.Theheatingofthemaintownsinthenorthofthecityismainlyconcentratedintheheatingsystem,suchascentralheating,naturalgasheatingandsoon.Centralheatingmodeofheatandheatingrangeisfarlessthanthedemandfortheresidentsofthepresentstage.Withtheeliminationofbackwardproductioncapacitypolicyinthecountrytopromoteenergy-savingemissionreduction,geothermalandhotdryrockcansavefuelandreduceenvironmentalpollutioncharacteristicsofnewenergy,inthefuturewillbecomethemainheatingmode.Keywords:geothermalenergy;renewableenergy;geothermalpower;centralheating;hotdryrock目录TOC\o"1-3"\t""\h\z\uHYPERLINK\l_Toc125091.干热岩的介绍与发展PAGEREF_Toc125091HYPERLINK\l_Toc56191.1干热岩的介绍PAGEREF_Toc56191HYPERLINK\l_Toc75652．干热岩发电PAGEREF_Toc75651HYPERLINK\l_Toc256942.1我国干热岩资源分布PAGEREF_Toc256941HYPERLINK\l_Toc124132.2如何最佳选址开发PAGEREF_Toc124132HYPERLINK\l_Toc322842.3开发干热岩有哪些益处PAGEREF_Toc322842
