본 발명은 태양열리시버에 관한 것으로서, 보다 상세하게는 집중 입사되는 태양열을 흡수하여 외부에서 유입되는 공기나 유체를 가열함으로써 발생되는 스팀 및 가열공기에 의해 터빈을 작동시키는 태양에너지플랜트용 태양열리시버에 관한 것이다.The present invention relates to a solar receiver, and more particularly, to a solar receiver for a solar energy plant that operates a turbine by steam and heating air generated by absorbing concentrated incident solar heat and heating air or fluid introduced from the outside. will be.

일반적으로, 태양에너지플랜트(Solar energy plant)는 거울로 태양광을 반사시켜 태양열 리시버(Receiver)에 태양열을 모아 공기를 가열한 후 터빈(Turbine)을 작동시켜 전기에너지를 발생되게 한다.In general, a solar energy plant reflects sunlight to a mirror, collects solar heat in a solar receiver, heats air, and then operates a turbine to generate electrical energy.

이러한, 태양에너지플랜트는 도 1a와 같이 태양광 집중 시스템(Concentrating solar system), 공기 회로(Air circuit), 발전 시스템(Electric power generating system)으로 구성된다.The solar energy plant is composed of a concentrating solar system, an air circuit, and an electric power generating system as shown in FIG. 1A.

여기서, 태양광 집중 시스템은 접시형의 일광반사거울(10), 일광반사거울(10)에서 집중 반사되는 태양열을 흡수하는 태양열리시버(Solar receiver, 20)로 구성된다.Here, the solar light concentrating system is composed of a solar receiver (Solar receiver, 20) for absorbing the solar heat intensively reflected from the plate-shaped sun reflection mirror 10, the sun reflection mirror (10).

그리고, 공기 회로는 태양열리시버(20)에 모아진 태양열에 의해 가열된 약 680℃의 공기가 순환하는 배관(40), 공기의 흐름을 개폐하는 복수개의 밸브(50), 공기의 강제순환을 유도하는 송풍기(Blower, 60), 태양열을 저장하는 열 저장소(Thermal storage, 70), 스팀을 발생시키는 스팀 발생기(Steam generator, 80)로 구성된다.In addition, the air circuit includes a pipe 40 through which air of about 680 ° C. heated by solar heat collected in the solar receiver 20 circulates, a plurality of valves 50 that open and close the flow of air, and induces forced circulation of air. Blower (Blower, 60), the heat storage (Thermal storage, 70) for storing the solar heat, and a steam generator (Steam generator, 80) for generating steam.

또한, 발전 시스템은 스팀 발생기(80)에서 발생된 약 65 bar, 460℃의 스팀에 의해 구동되면서 전기에너지를 발생시키는 터빈(Turbine, 90) 등으로 구성된다.In addition, the power generation system is composed of a turbine (Turbine, 90) and the like generated by the steam generator 80 is generated by the steam of about 65 bar, 460 ℃ steam.
