摘要:

利用低温热能的热再生过程是热再生电池(thermally regenerative battery,TRB)系统的重要组成之一,针对TRB的产电和热再生过程,研究了使用再生电解液的TRB产电性能以及温度和强化传热传质措施对热再生过程的影响。研究结果表明,产电过程中,使用再生电解液的TRB最大功率为5.7 mW,比初始电解液的TRB(最大功率为6.5 mW)低14%;热再生过程中,提高温度可以明显强化热再生过程,采用玻璃球床和搅拌措施也可以有效提高热再生过程的性能。

Abstract:

Regeneration using low-grade thermal energy is one of the most important components of the thermal regenerative battery (TRB) system. In this study, the effects of the regenerative electrolyte on the performance of TRB and the effects of temperature and mass transfer on the thermal regeneration are studied. The experimental results showed that the maximum power of TRB using regenerated electrolyte was 5.7 mW, which was 14% lower than that of TRB using initial electrolyte (6.5 mW). In the process of thermal regeneration, the increasing of temperature can obviously strengthen the process of thermal regeneration, and the performance of thermal regeneration can also be effectively improved by using glass balls bed and stirring.

Key words: thermal regenerative ammonia-based battery, electrochemistry, maximum power, mass transfer, heat transfer
