技术领域 FIELD

[0001] 本发明涉及一种中低温太阳热能品位间接提升的方法及据此提出的太阳能和化石能源综合互补的化学回热循环系统(SOLRGT)。 [0001] The present invention relates to a method of low-temperature solar thermal energy indirectly enhance the quality of and pursuant to the proposed comprehensive solar energy and fossil complementary chemical regenerative cycle system (SOLRGT).

背景技术 Background technique

[0002] 目前与本发明相关的技术主要包括中低温太阳能利用技术和利用化学回热循环发电技术,其各自技术的发展状况和系统特征如下: [0002] Currently in the art related to the present invention mainly comprises a low temperature solar energy utilization in use of chemical and heat recovery cycle power generation technology, development of their respective technologies and system characteristics are as follows:

[0003] 1)中低温太阳能利用技术 [0003] 1) low temperature solar energy utilization

[0004] 鉴于化石能源资源的有限性及其利用过程中产生污染的严重性,开拓新型洁净能源资源(特别是非碳能源)转换利用成为可持续发展的一个重要方面。 [0004] Given the limited contamination generated severity of the process and use of fossil energy resources, develop new clean energy resources (especially non-carbon energy) converted using an important aspect of sustainable development. 近年来,太阳能以其独具的储量无限性、存在的普遍性、开发利用的清洁性以及逐步提升的经济性等优势获得广泛关注,成为解决能源短缺、环境污染和温室效应的有效途径之一。 In recent years, solar energy get the advantage of its unique infinite reserves, ubiquitous existence, development and utilization of clean and the economy, etc. gradually increase the attention, becoming one of the effective ways to solve the energy shortage, environmental pollution and the greenhouse effect .

[0005] 当前,太阳能利用技术的主要发展方向是太阳能光电转化和光热转化,其中光热转化的太阳能热动力发电又是未来二三十年最具吸引力的太阳能技术。 [0005] Currently, the main direction of development of solar energy technology is transforming solar photovoltaic and solar thermal conversion, in which the photothermal conversion of solar thermal power generation and the next two or three decades is the most attractive solar technology. 但是诸如储能难和能量转化效率低等造成的太阳能发电技术成本居高不下,一直是困扰太阳能热动力发电系统大规模发展和工程应用的重大瓶颈。 But the cost of power generation technologies such as solar energy conversion and storage difficulties caused by low efficiency high, has been a major bottleneck in troubled solar thermal power generation system large-scale development and engineering applications. 究其原因,一方面是太阳能能量密度低、时空分布不连续;另一方面且更为重要的是太阳能集热效率与热力循环热功转换效率一直存在难以调和的矛盾。 Reason, on the one hand the solar energy density is low, temporal and spatial distribution discontinuity; on the other hand, and more importantly, the efficiency of the solar collector and the thermal power conversion efficiency of a thermodynamic cycle has been difficult to reconcile the conflict. 目前太阳能热发电技术以及新兴的热化学能量转换技术(如天然气重整的热化学能量转化系统等)研究多集中在900〜1200°C的高温太阳热能的转化和利用,且多为高温集热和热化学转换等部件性能的提高和相关新材料的研发。 CSP current and emerging thermochemical energy conversion techniques (such as natural gas reforming thermal chemical energy conversion system, etc.) using the Transformation and concentrated in 900~1200 ° C high temperature solar heat, and more for a high temperature heat collector and improve the development of new materials and related components thermochemical conversion properties. 1000°C以上的高温集热无不以设备复杂、投资成本高和光热转换效率低为代价。 A high temperature above 1000 ° C all collector devices in complex, high investment costs and the photothermal conversion efficiency is low expense. 相对而言,当前150〜350°C的中低温太阳能热利用技术以其良好的集热性能和经济简单的集热装置获得大规模商业化。 In contrast, to obtain the current large-scale commercial solar thermal low temperature 150~350 ° C by collecting its good technical performance and economy simple heat collecting apparatus. 这个温度范围的集热器大多采用低聚光比的简单聚光装置,集热性能良好,集热效率一般能达到60%以上,且有效避免了高温太阳能能量转化系统的高成本代价。 The temperature range most simple collector means collecting the lower concentration ratio, good performance collector, collector efficiency is generally more than 60%, and avoid the expense of costly high-temperature solar energy conversion systems. 然而,由工程热力学原理可知工质的温度越低,实现热转功越困难,目前中低温热量的利用尚缺乏行之有效的技术。 However, the principles can be seen from the lower working fluid temperature engineering thermodynamics, heat transfer more difficult to achieve power, the current lack of effective technology use in low-temperature heat. 与此相对,常规能源利用系统经过百余年的发展,技术和工艺已日臻完善,如先进的燃气轮机工质温度已达1400°C以上。 In contrast, conventional energy systems through a hundred years of development, has been improving technologies and processes, such as advanced gas turbine working fluid temperature has reached more than 1400 ° C. 设想太阳能等可再生能源如果得以在常规能源系统中实现能量转换和释放,不但可以替代部分化石能源消耗,减少相应的污染物排放,更将极大地提高可再生能源能量释放品位和热转功效率,同时缓解其不稳定、不连续的供给难题。 Contemplated that if renewable energy such as solar energy can be achieved in a conventional energy conversion systems and release, can not only replace part of fossil energy consumption and reduce emissions corresponding more greatly improve the quality and efficiency of power transfer thermal energy release renewable energy , while alleviating its instability, discontinuous supply problems. 中低温太阳能和化石燃料的互补梯级利用有望为同时解决太阳能能量转化效率低和实现化石燃料的清洁利用提供一条全新的途径。 Complementary rungs low temperature solar energy and fossil fuel use is expected to solve the same time providing a new way of low solar energy conversion efficiency and achieve clean use of fossil fuels.

[0006] 多能源互补系统中,中低温太阳能可以和热力系统中某些物理吸热过程相集成(热集成),如蒸发过程、回热过程;也可以和某些吸热化学反应相集成(热化学集成),如热解反应和重整反应等。 [0006] Multi complementary energy systems, low-temperature solar thermal system can be certain physical integrated endothermic (heat integration), as the evaporation process, the heat recovery process; and some may be integrated endothermic chemical reaction ( thermochemical integration), as the reforming reaction and the pyrolysis reactions. 前者如N. Lior和K. Koai提出的蒸汽朗肯循环互补系统,低温段工质水吸收约100°C太阳能热量蒸发,高温段化石燃料燃烧提供热量使蒸汽过热,形成不同热源在不同温度段的匹配利用,太阳能热输入份额高达80%,系统热效率可达18%。 The former N. Lior and K. Koai proposed complementary steam Rankine cycle system, refrigerant low temperature section of about 100 ° C water absorption of solar heat evaporation, high-temperature stage burning of fossil fuels to provide heat to superheat the steam, the formation of different heat sources at different temperature stages matching using solar heat input share up to 80%, up to 18% thermal efficiency of the system. 后者如H. Hong和H. Jin提出的一种中低温太阳能与化石燃料热化学互补的联合循环系统,利用甲醇燃料在中低温条件下的热解特性,以200〜300°C的太阳能驱动甲醇热解吸热反应,生成以H2和CO为主要成分的合成气,从而使低品位太阳能转化为高品位合成气化学能;合成气驱动燃气/蒸汽联合循环做功,实现了中低温太阳能品位的提升和其在动力系统中的高效转化。 An latter low temperature and solar H. Hong H. Jin proposed thermochemical complementary fossil fuels combined cycle system, using a methanol fuel pyrolysis characteristics under low temperature conditions, in order to drive the solar 200~300 ° C methanol endothermic pyrolysis reaction to produce synthesis gas of H2 and CO as main components, so that the low-grade to high grade solar energy into chemical energy of the synthesis gas; syngas drive the gas / steam combined cycle work, to achieve a low temperature solar grade and enhance its efficiency in a power conversion system. 其案例分析中,太阳能热输入比例为18%,太阳能发电净效率和系统佣效率分别达到35%和60. 7%,但该计算忽略了透平叶片冷却影响。 In which case the analysis, the proportion of solar heat input is 18% and the net efficiency of solar power systems Maid efficiency of 35% and 60.7%, respectively, but the calculation ignores the influence of cooling the turbine blades.

[0007] 2.利用化学回热循环发电技术 [0007] 2. by chemical regenerative cycle power generation technology

[0008] 化学回热循环在燃气透平Brayton循环的基础上引进了燃料的化学重整反应,当燃料为甲烷时,反应主要为: [0008] Chemical regenerative cycle gas turbine Brayton cycle based on the introduction of chemically reforming reaction of the fuel when the fuel is methane, the main reaction is:

[0009] CH4+H2OeCO+ 3Η2 ΔΗ = 206. IlkJ/(mol CH4) [0009] CH4 + H2OeCO + 3Η2 ΔΗ = 206. IlkJ / (mol CH4)

[0010] CO + H2OCO2+H2 ΔΗ = -41. 17kJ/(mol CO) [0010] CO + H2OCO2 + H2 ΔΗ = -41. 17kJ / (mol CO)

[0011] [0011]

CnHm + nH20 nCO + (m / 2 + n)H2 CnHm + nH20 nCO + (m / 2 + n) H2

[0012] 当燃料是甲醇时,反应主要为: [0012] When the fuel is methanol, the reaction mainly:

[0013] CH30H+H20 CO2+H2 Δ H = 49. 47kJ/ (mol CH3OH) [0013] CH30H + H20 CO2 + H2 Δ H = 49. 47kJ / (mol CH3OH)

[0014] 它们都是吸热反应,压力越小、温度越高、水碳比越高,燃料转化率越高。 [0014] They are endothermic reaction, the smaller the pressure, the higher the temperature, the higher the ratio of steam to carbon is higher, the fuel conversion. 燃料转化为合成气后,燃料的热值得以改善,相比原来余热锅炉、回热器中对烟气余热的物理回收过程,化学回热循环增添了重整器中对烟气余热的化学回收过程,从而使循环达到较高的效率。 After the fuels into synthesis gas, hot fuel worth to improve, compared to the original waste heat boiler, in the regenerator flue gas waste heat recovery process of the physical, chemical, thermal cycling back add chemical reformer flue gas waste heat recovery process, thereby to achieve a higher cycle efficiency. 甲烷是天然气的主要成分,较甲醇而言应用更广。 Methane is the major component of natural gas, in terms of wider application than methanol. 但是甲烷重整反应在镍基催化剂下一般需要800°C以上的高温,而在330°C以下基本不发生反应。 However, methane reforming reaction in the nickel-based catalyst generally require a high temperature above 800 ° C, the reaction occurs substantially at 330 ° C or less. 因此直接以中低温太阳能提供反应热来驱动甲烷重整反应是不可行的。 Therefore provided directly to the low temperature solar heat the reaction to drive the reforming reaction of methane is not feasible. 相较而言,甲醇在200〜300°C即可实现完全重整。 In contrast, methanol 200~300 ° C to achieve complete reforming. Kesser等人1994年模拟结果表明:以甲烷为燃料的基本化学回热循环(无间冷再热) 的热效率达到48. 8%,高于相同注汽率下的注蒸汽循环。 Kesser et al. 1994, simulation results show that: the basic chemical methane fuel regenerative cycle (seamless cold reheat) the thermal efficiency of 48.8%, higher than the steam injection cycles at the same rate of steam injection. 同时,由于合成气中含有大量的水蒸汽,循环的NOx排放相当低、比功大幅提高。 Meanwhile, since synthesis gas contains a large amount of steam, the NOx emission is very low circulation, a substantial increase in specific power.

[0070] 具体实施例循环平衡工况热力性能参数参看表2,表2同时在相同的假设条件下(包括透平初温1308°C、节点温差及部件性能等),对常规间冷化学回热燃气轮机(IC-CRGT)循环和SOLRGT循环进行了模拟对比,可见SOLRGT系统中,太阳热输入份额为20. 3%,化石能源节约率可达23. 3%。 [0070] Example of Thermal Ping Heng cycle performance parameters DETAILED DESCRIPTION Referring to Table 2, while Table 2 under the same assumptions (including turbine initial temperature 1308 ° C, the temperature difference between the node and component performance, etc.), on the back between the conventional cold Chemistry Gas turbine (IC-CRGT) SOLRGT cycles and cycles were simulated comparison, visible SOLRGT system, the solar heat input share of 20.3%, fossil energy conservation rate of 23.3%. 太阳热能净转功效率可达沈.5%,远高于同样温度下常规太阳能热发电系统。 Net transfer of solar thermal power efficiency of up to 0.5% sink, much higher than a conventional solar thermal power generation system at the same temperature. 单位发电量(X)2排放为342. 7g/kffh,比IC-CRGT系统中低23. 3%, CO2相对减排量和化石能源节约率相一致,这是因为(X)2排放量和化石燃料消耗量成正比。 Power generation unit (X) 2 emissions 342. 7g / kffh, 23.3% lower than the IC-CRGT system, CO2 reduction and the relative rates of fossil energy conservation consistent because (X) 2 emissions and fossil fuel consumption is proportional. 需要指出的是,上述结果是在理想情况下、也即在太阳热能温度满足220°C水蒸发要求的情况下得到的。 It should be noted that the above result that in the ideal case, i.e. meet the solar heat temperature 220 ° C to give a case where water is evaporated claims. 如果太阳热能达不到上述温度要求,需要采用补燃或降低蒸发温度(压力)、蒸发后再提升蒸汽压力至重整反应要求压力等情况下,系统效率会相应降低。 If the temperature of the solar heat can not reach the above requirements, or need afterburner reduce the evaporation temperature (pressure), and then evaporated to elevate the vapor pressure of the reforming reaction requires pressure, the system becomes less effective.

[0071] 和常规化学回热燃气轮机(CRGT)系统相比,新系统需要增设中低温太阳能集热设备,可以采用技术相对成熟、造价较低的槽式集热器。 [0071] and conventional chemical regenerative gas turbine (CRGT) system, the new system needs additional low-temperature solar collector device can be used relatively mature technology, low cost trough collector. 槽式集热器在中低温应用场合具有优良的集热性能,即使在lOOW/m2的太阳辐照强度下也可达到50%以上的集热效率。 Trough collector having superior collecting performance in low-temperature applications, can reach more than 50% even in the solar collector efficiency irradiance lOOW / m2 of. 应该指出的是,系统效率和太阳能热转功效率的提升与系统经济性改善直接相关;此外系统在CO2减排、及化学回热循环本身在NOx排放等方面的优势也是进行经济性分析时应该考虑的因素。 It should be noted that the lifting directly related to system efficiency and solar thermal power transfer efficiency and economy improvement system; in addition, the system CO2 emissions, and chemical regenerative cycle itself advantages in terms of NOx emissions should also carry out economic analysis consideration.
