这项工作的重点是使用钙循环过程（CaL）在集中太阳能发电（CSP）厂的热化学能量存储（TCES）。廉价、丰富且无毒的天然碳酸盐矿物，如石灰石和白云石，可用于该应用中，通过CaCO 3的循环煅烧/碳酸化来储存能量。在最近的工作中，已经提出了一种封闭的CO2循环用于有效的CaL-CSP集成，其中来自碳酸化器的过量流出物中的CO2用于通过燃气涡轮机发电。过程模拟表明，热电效率提高碳酸化器的压力和温度，只要多晶CaO转化率不受影响。另一方面，已经建议仅使用一个反应器用于煅烧和碳酸化以降低资本成本。然而，在本工作中所示的实验结果表明，烧结是显着增强的反应器中的压力增加。是...
This work is focused on the use of the Calcium-Looping process (CaL) in Concentrated Solar Power (CSP) plants for Thermochemical Energy Storage (TCES). Cheap, abundant and nontoxic natural carbonate minerals, such as limestone and dolomite, can be employed in this application to store energy through the cyclic calcination/carbonation of CaCO3. In a recent work, a closed CO2 cycle has been proposed for an efficient CaL-CSP integration in which the CO2 in excess effluent from the carbonator is used to generate electricity by means of a gas turbine. Process simulations show that the thermoelectric efficiency is enhanced as the carbonator pressure and temperature are increased provided that the multicycle CaO conversion is not affected. On the other hand, the use of just one reactor for both calcination and carbonation has been suggested to reduce capital cost. However, the experimental results shown in the present work indicate that sintering is notably enhanced as the pressure in the reactor is increased. S...
