摘要
在目前能源资源日趋紧张、环境压力逐渐增加的情况下,发挥可再生清洁能源的优势,发展新型发电技术尤为重要。本文介绍了太阳能燃气轮机发电系统的工作过程、项目试验以及关键技术的研究现状,对集热、储热、回热和控制策略等关键技术进行了总结。针对关键技术指出:管式和容积式吸热器可将空气加热至600~1 000℃高温,且布置在透平机入口前技术优势更为明显;显热储热材料加热后温度可升至1 000℃以上,化学储热材料储放热温度稳定且储热密度高,可达0.5~1.0 k W·h/kg;回热器以主表面式和板翅式为主,以提高能源利用效率;控制策略需要协同系统各部件,其优化方案仍需进一步研究。
With the increasing pressure of energy shortage and the environment pollution, it's important to take the advantage of the renewable clean energy for new power generation technology. This study introduces the working process, project experiments and key technologies of the solar gas turbine power generation system, and summarizes the key technologies: solar heat collection, heat storage, heat recovery and control strategy. Tubular and volumetric receiver can heat air to the high temperature(600~1 000 ℃), and is better to be arranged before the inlet of turbine. Sensible storage material can be heated to above 1 000 ℃, while chemical storage material charging/discharging temperature is stable and has high heat storage density(0.5~1.0(k W·h)/kg). Primary and plate-fin recuperators are widely used to improve energy efficiency. Different parts of system are coordinated by control strategy, which need be optimized.
